Alignment discussion:
- ODATA is an older model (developed by Microsoft, published OASIS standard) for business related data.
  Are there any reuse/adopt opportunities or does it not apply? See also web site.

Monday 2021-10-25

We suggested to rework the overview picture into one part showing how components are stored in repository, and another for deployment
LiveSim is not connected at both ends. The diagram suggests there is a deployment where data is fed from livesim but also fed back into livesim, which doesn't make sense. You either collect real data (from some kind of VSS Feeder writing into in-vehicle state storage) or you feed the system from the livesim. It is true that Livesim consumes a OVDS database format, but it does not
Can we start using some kind of online editing tool or common format in the future? (anything that allows other people to change)
- YEd?
- Fallback is always PPTX file (works in MS Office and LibreOffice)

Monday 2021-08-23

Geotab data format to VSS conversion is possible. About 50 signal translations have been defined.
- Data sets can then be provided (in OVDS format)
- Position information likely coming (pending consent).
- examples: position, speed, ignition, oil temp, turning indicators, seat belt
- 5-10 vehicles, that type of range.
- How can/shall we use this data?
Stephen reminds about VSS-formated dataset that Access has defined before (available with a demo in GitHub).
CCS demos have before focused on Vehicle→OEM cloud parts. Development in the usage of data, cloud based applications, and deployment/automation as previously discussed.
Curve logging implementation in VISS is new compared to last AMM. It can be demonstrated.
Android app - reads from VHAL sends signal to cloud. Opportunity to use VSS and/or VISS?

ISO ExVe

following the discussion on ISO ExVe in the CVII workshop, Philippe reports the Renault representative in this WG contacted him and confirmed he will organize a presentation of CVII to the vehicle data subgroup of the French PFA (French equivalent of German VDA) in September
Gunnar and Philippe provide a short debrief to Florian on the outcome of the call with ISO WG6 participants on 23 June (ISO WG6 convenor, Stellantis representative, Audi representative, Gunnar, Ted, Philippe). Call went out well. A presentation of CVII to ISO WG6 is likely to be scheduled at the next meeting of ISO WG6 in late August / early September
summary of discussion with ISO people is below
- convenor: in ISO we are starting to work towards enabling third parties to get data and functions embedded in the car within the ExVe architecture, we realized it is difficult to get a similar set of signals from the different OEMs, this is why we decided to move only to an harmonization of the data description among the vehicle OEMs
- Gunnar exposes the GENIVI/W3C vision
- Stellantis : we do not want to harmonize the vehicle EE architecture among the OEMs, we do not want to have the same characteristics for the data we get
  - there is no direct access between the neutral server and the vehicle
  - the neutral server knocks at the door of each OEM cloud interface
- Audi: there is no definition of accessible data, we do not define which data are provided, we are looking for a generic way to describe data
- Gunnar: ISTM the ExVe interest is with the meta-model
- convenor: we are discussing more about API catalog than data catalog; it will be something like a function catalog
- Audi: in our specifications, we are describing the way and how the functions can be accessed (with security) and not the resources themselves
- convenor: asks where we consider putting the layers implementing the CVII translation / conversion
- Stellantis: you should talk to Bosch BSH, they have a similar block diagram for the home automation
- convenor: shows one slide of the presentation he made to UNECE in Geneva a couple of months ago, the slide shows the different ways to access the vehicle data

tech brief

Iyyaz said via email that he will send the draft document on Wed/Thu this week

OPIN

in the minutes of last Friday"s OPIN meeting, Steve and Philippe got an action item to provide a OEM oriented use case (Steve suggested a driver distraction use case) and a (truck) fleet management use case. Philippe suggested in the same call the use case related to the refrigeration of the cargo bay (monitoring of the cargo temperature)
Gunnar: concerning trucks and their cargo, we have a signal in VSS indicated whether the trailer is hatched / not hatched
Gunnar: concerning the OEM use case, we have in VSS signals that could be relevant for detecting the driver's behavior
Gunnar: IMHO the technical architecture is in place and we should not be contemplating architectural changes due these additional use cases
Philippe: asks whether Ted could find some help within Geotab to provide a truck fleet management scenario to share with OPIN
Philippe: proposes to reach out to Kevin and ask whether High Mobility could provide a OEM use case (e.g. driver distraction)
discussion follows on the coordination between Catena-x and VSS and OPIN and the structuring of vss signals

quick roundtable to welcome Florian

discussion on the CCS work breakdown structure

Gunnar : current CCS project focus is on the implementation of the CCS end-to-end architecture
Gunnar explains the status of the implementation (using the diagram in CCS Reference Architecture - Work Breakdown Structure
Florian welcomes favorably the CCS approach to promote the use of open source and off-the-shelf components for the implementation
Gunnar focuses today's discussion on the identity and access management
Iyyaz: Hydra/Okta challenging to set up. Okta seeems popular. Hydra is the implementation. See https://oauth.net/code/
.....AWS, MS/Azure, etc. have their own offered services.
...Need ideas / definition of task to progress this within CCS PoC implementation.
Gunnar: Self-hosted solutions?
Iyyaz: They are all hosted services. Some configurability regarding which servers to use.
Signing up as a developer to Okta gives access to a limited account with a certain number of users (quite many,~7000)
Identity and access management is a moving target, important to track security updates, etc. which speaks to partnering with expert companies.

May 10

Scope CCS project work (in relation to other CVII projects)
Kevin: Worth building the implementation fully. Cannot contribute (more) code at this time.
Gunnar: Let's scope CCS for the "cloud" part of the architecture. Strictly in-vehicle discussion perhaps a different CVII sub-project.
Gunnar: Current CCS project scope is quite wide, and describes something similar to the first steps of CVII. Let's try to narrow/clarify scope now.
Philippe: Might need revising the ticket backlog to match.

Workplan for the next 6 months (preparation of Friday 7 May CCS workshop)

Kevin: what could be important for an OEM ?
Ulf: important to show an end2end connection from the vehicle to the cloud, obd in the vehicle, we would need a better dataset from the obd, Geotab could be asked to provide a more comprehensive dataset, but to be really demonstrative, we would need someone working on the cloud side
Gunnar: @Ted: what about the grapher project ?
Ted: https://www.w3.org/auto/wg/wiki/Vss_data expose real-time data on to grapher (MIT, SRI, U.Memphis, Geotab are involved in a R&D project and asked for a grant)

CCS-202 - Getting issue details... STATUS created, please add your topics there

GAIA-X

Benjamin: this was a very high level presentation, a bit disappointing, the only use case I found relevant for automotive relates to the supplier chain
Gunnar: we need to be proactive and reach out to them and tell the story that CVII will produce one of the items they need
Philippe: the French "hub" of GAIA-X will gather on 7 May morning (CET); will joint it
Philippe: we need also to continue reaching out to ISO ExVE

demo for AMM

Ulf: http-based demo done
Ulf: MQTT-over-viss client is now implemented (separate executable), It is in the https://GENIVI/ccs-client repository
Ulf: Old implementation verified that requests are found in the tree.
- ...Now the paths are different.
- ...I need for the demo some new populated OVDS, at least one database.
- ...It is a bit tricky to keep the correct VSS version.
Gunnar: Could we make this less tricky ? It is often good to be able to catch errors on different levels of the stack.
Ulf: Another argument: OVDS server should be able to store data from different models etc.
- ... anyway OVDS server has now removed this check so it accepts ANY path for the moment.
Ulf: I need a new populated OVDS from Geotab, working on it.
Ulf: The demonstration - I could run the demo natively but running on docker should be much better, who can fill up the docker structure with the new components
- If container setup in CCS-arch-demo is not updated I will do the demo manually. But in that case I will do pre-recording of the demo.
- Gunnar: Sometimes it's good to have a recording anyway, as a backup.
Initial plan: 3 laptops in network.

AMM content

deployment on google cloud talk still to be confirmed by Geotab
TODO Ulf Bjorkengren please check with Glenn the outcome of the internal meeting about this talk
Iyyaz: Mostly working on terraform now. Potential demo. Slides were previewed on last CVII Tech Stack meeting.
- ... discussion on technical level of presentation/discussion at workshops at AMM.
- Conclusion: It's good to assume people are not experts in, say, terraform, but that they will pick it up quickly if there is a quick intro before moving into the details.
Gunnar: we have the possibility to reuse the timeslot for google cloud and assign it to Iyyaz's talk and demo

Kevin: yes, we will join and present the use cases we have implemented

end2end demo at AMM

Ulf explains the demo architecture, look at the picture https://at.projects.genivi.org/jira/secure/attachment/11702/mqtt_vissv2_arch.jpg
- picture attached to CCS-196 - Getting issue details... STATUS
Philippe: it would be good to have a complementary demo on the cloud side on the top of the (CCS) communiucation framework architecture and that we go one step further from what we demoed before
Gunnar: I was thinking of possible extensions towards many (hundreds) of clients to look into the scaling
discussion follows on bringing together Ulf's and Iyyaz's demos either on the paper or at implementation level
Iyyaz: my intent is to show the use of terraform and how the deploymentcan be done on various cloud infrastructures, another possible approach for the deployment is to use containers
TODO Iyyaz to provide a short slide deck (i.e. early overview) on how the deployment could be done
- CCS-199 - Getting issue details... STATUS created
then we will discuss on what we might end up with for the implementation in the AMM demo
discussion on terms and definition of "edge"
- Iyyaz: in the context of our discussion in CCS, my understanding is that vehicle = edge and we are talking of "edge-to-cloud"
- Iyyaz: edge = everything that have a small compute capability, the edge needs to tell the cloud about the (vehicle) presence
- TODO Iyyaz to provide our definition of "edge" as compared to what Bosch uses as a definition on "edge" in their recent code drop
  - CCS-200 - Getting issue details... STATUS created

alignment of Sensoris and VSS data model

CCS-195 - Getting issue details... STATUS Benjamin reported about the review he made prior to the call
- Benjamin reviewed the slide deck shown at the CVII workshop (slide deck is here)
- Some feedback on the slide deck shared:
  The overlap of signal categories is clear, Sensoris has both internal and external signals where VSS only has internal ones. What could complete this is that:
  - VSS only defines signals as things that your car senses/controls, not necessarily abstract information. For instance, the signal WindCondition does not exist in VSS but something equivalent could exist.
  - VSS orders signals by vehicle branch (part, component), while Sensoris has an approach based on use cases
  I believe these are the "notable differences" mentioned in slide 5.
  The proposals for collaboration are pretty clear and extensive. I would also include the possibility of organizing a workshop with developers of both community trying a set of use cases with a combination of both specs to find out where practical overlap/conflicts would happen. Another possibility is to have a spec importing the other (e.g. Sensoris using the VSS signal list like a catalog, translated into protobuf and Sensoris messages).
- TODO Gunnar to forward Benjamin's inputs to Stefan Werder who at Bosch is working on the alignment of Sensoris and VSS data models, ticket rassigned to Gunnar

review of tickets related to the deployment of CCS communication framework on cloud infrastructure

CCS-101 - Getting issue details... STATUS
- Kevin: presents the analysis made by High Mobility on using terraform (please look at the comprehensive comment added to the ticket)
- Gunnar/Philippe: this sounds like a plan
- Gunnar: what would happen if we change the database (like to a pure sql database) ? some parts of the demo use REST interface, however some part of OBDII interface should be changed, Ulf agrees
CCS-189 - Getting issue details... STATUS
- Iyyaz: at Cobrasphere, we tried to build CCS and we have not succeeded yet
- Iyyaz: it seems that ubuntu 10.x does not support some features
- Gunnar: that kind of things happen when you are not using ubuntu long term support
- Iyyaz: would it be ok to use Alpine Linux ?
- Gunnar: yes it is possible
- Ulf: I know that Magnus Gunnarsson at Melco (who works in W3C) uses the Alpine distro
- Iyyaz: we will try to rebuild then
- Gunnar: modifications should be made as pull requests
CCS-192 - Getting issue details... STATUS
- Glenn: the challenge is to show the interopErability of the Geotab analytics tools with CCS
- Ulf: explains the update made in the vehicle client component, we have a solution for transporting VISS onto MQTT
- Ulf: we use moskito server for this purpose
- Stephen L: please note big picture is out of date in the wiki

sprint review and update

CCS-108 - Getting issue details... STATUS cancelled, won't fix, no need to go for a production-grade component
CCS-111 - Getting issue details... STATUS commented
- Gunnar: The principles for automatic/table-based translation can be seen in AASIG-122. The spreadsheet shows mapping between Android properties and VSS signals - and in one column you can see the intention is to define the type of conversion that is needed for each conversion (full equality, type conversions, or scaling through a linear transformation formula, or a more complex situation). Many input sources, such as CAN, would work similarly.
CCS-156 - Getting issue details... STATUS commented
- Repository is now up. Draft tech brief is being developed currently. Official name will be: Curve Logging. Will soon be sent to Gunnar for review.
CCS-59 - Getting issue details... STATUS commented
- Michael came back to ask to sync up FusionProject with the CCS and CVII work. Meeting pending probably to be booked this week.
CCS-102 - Getting issue details... STATUS commented
- Discussion today about new potential parts:
  - AWS/cloud provider implementation ideas -> see CCS-101
  - New features in VISS communication could be part of next demo (subscription now also exists in client, VISS-over-MQTT). Also access control which was not demoed before.
  - Multi-client demo (using different transports)
CCS-83 - Getting issue details... STATUS commented
- Gunnar: Some more description of VSS-layers in GitHub pull request, but further discussions ongoing. The usage of VSS layers to define access control is still there (not further improved however).
CCS-123 - Getting issue details... STATUS commented
- One related idea proposed in CCS-101 was to use AWS RDS service,
- but also continue looking into a time-series database

rescoping of CCS project

Kevin: CVII call of last week was positive, Q. can we embed our CCS poc in the bigger CVII picture ?
quick look at CCS Reference Architecture - Work Breakdown Structure
Gunnar: there are 2 areas where it is still worth completing the implementation
- the graphql implementaion
- the access management
Iyyaz: concenring access management, are you looking for an implementation on the cloud side ?
@kevin: is it for the neutral server to authenticate or for 3rd parties ?
Kevin: this is for both
Gunnar: it does not replace the authentication on the pipe to the vehicle, VISS protocol does have a definition of access control
Gunnar: shows the vss-graphql repository
Christian H: why don't we collaborate with kuksa project on this, since they have implemented it
- https://github.com/eclipse/kuksa.val
Gunnar: is it aligned with OAuth ?
Christian H: this is to be checked with Sebastian Schidlt
discussion on the various approaches of authentication
Gunnar / Ulf: we use the same authentication mechanism but not the same authentication token on the cloud side and the vehicle side
Iyyaz: what are the actions resulting from this discussion ?
Gunnar: IMHO there is a need to review the kuksa code to check what can be reused
Gunnar: there is a need to cross-check whether kuksa project supports OAuth with Sebastian until next call
Gunnar: IMHO a deep knowledge of the OAuth2 specfication is necessary
Gunnar: we might be willing to explore which implementation exist in the open source
Iyyaz: I have been using the okta implementation of OAuth2, it is actually a service, but provides some code examples of how the service can be used
- https://developer.okta.com/docs/guides/
- okta supports jwt
- okta claims you do not have to bother about the updates of the various software components used
Christian H: the authenticator should be the code we are looking for
Iyyaz: points to https://medium.com/decentralized-identity/the-universal-resolver-infrastructure-395281d2b540
Christian H: points to https://dev.uniresolver.io/
TODO look into the kuksa code
- Christian: on Bosch side the developer is "wenwenchen", we should open a ticket in github to get in touch with the developer
- Christian: I will check with wenwen which material is available for explaining the authentication approach in kuksa
- CCS-193 - Getting issue details... STATUS created and assigned to Christian H
TODO Iyyaz to explain the rationale for using an external authentication service (like okta)
- CCS-194 - Getting issue details... STATUS created and assigned to Iyyaz
Philippe: I recommend that we use the mailing list for this because it gives more visibilty than comments in a Jira ticket
CCS-127 - Getting issue details... STATUS thrown into the current sprint

Vehicle data model

CCS-141 - Getting issue details... STATUS
- Gunnar: presents the results of the review of autopilot project docs he made
- Gunnar: data files containing values measured in test trials, however we do not have a lot to learn for the development of VSS
- Philippe: a short comment, it might be worth checking whether those data files might used as inputs for testing in CCS poc
CCS-53 - Getting issue details... STATUS
- Gunnar: IMHO we should ask Benjamin K to look further into it
- Philippe: IMHO we should go through Bosch to reactivate the liaison with Sensoris, Jira ticket commented

Nate: kafka seems to be more mature, nifi is on our watch list though
Gunnar: do you use other cloud technos ?
Nate: yes, we are trying out snowflake https://www.snowflake.com/
discussion between Mike and Rex on the data processing
Rex: are those technos only cloud based ?
Mike: yes, Rex will follow up with Mike
Gunnar: I can see overlap and complementarity of this work withthe CCS analysis on cloud technologies
Mike: we updated the table already filled in for AWS, IBM Cloud and CCS, updated table is there

discussion on CI infrastructure, discussion on containarization pros ans cons

CVII follow up

MS: Gunnar and Philippe and Ted (W3C) had a good call with MS MCVP team members last week, MS is very supportive of the CVII work, and wants to make sure the information about CVII is distributed in the MS organization, MS preferred language for describing data and data relationships is JSON-LD - JSON for Linking Data (which a W3C specification), url: json-ld.org, MS DTDL is based on JSON-LD
MS: Gunnar shows the slides about DTDL and various translation approaches he shared during the call with MS
Hyundai: Hyundai is working on a vehicle data model, but whether they want to help building a standard is still TBD
Sensoris: Gunnar has reached them out again in order to set up a coordination, this is work-in-progress on Sensoris side

Fosdem

TODO Ulf and Kevin with Gunnar's support will prepare an abstract for Wednesday 16 December
CCS-188 - Getting issue details... STATUS commented

GAIA-X & EATA

Philippe browses through the GAIA-X project web site: https://www.data-infrastructure.eu/GAIAX/Navigation/EN/Home/home.html
in the technical concept section - How GAIA-X project works ? it is stated that one focus area will be an "easy access to the available providers, nodes and services. Data will be provided through federated catalogues"
in the BMW/AWS press release, it is also stated that "The BMW Group will contribute its expertise from these use cases to the recently announced Automotive Alliance, which will be based on GAIA-X standards. As founding member (BMW Group) and “Day 1 Member” (AWS) of GAIA-X, the two companies are striving to further develop the Cloud Data Hub towards the GAIA-X standards for sovereign, secure and innovative data spaces"
although the data spaces referred to there might be rather relevant to parts and manufacturing, it would be good to determine whether this work complements or supersedes CVII work
then Philippe browses through the EATA alliance web site: https://eata.be/, both BMW and Hyundai are members together with Toyota and Mazda (and also Iveco and MAN truck manufacturers), does EATA complements, overlaps or supersedes CVI work ?

gap analysis between AWS and CCS framework

CCS-101 - Getting issue details... STATUS
Kevin: shows the analysis he made on AWS, this makes sense today because of the joint press release by BMW and AWS - look at https://telematicsnews.info/2020/12/08/aws-and-bmw-group-team-up-to-accelerate-data-driven-innovation/?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+telematicsnews+%28Telematics+News%29
Kevin: I initiated a gap analysis, i.e. an assessment of the mapping of AWS components on the CSS framework components, the initial results are captured in the Jira ticket
- for instance AWS greengrass would "override" Gen2 protocol implementation
- the name of Amazon timestream is mentioned : is this a time series database ?
Gunnar: do we identify some of these and try them out and integrate them ?
Kevin: 3rd party APIs to the data is not different for automotive than for other domains and might be reused, VSS2 might be a better fit because it was designed for automotive use only
Gunnar: CVII - do we convert from VSS to firehose or greengrass to use them ? for instance MS said they need everything to be translated to MS DTDL
Kevin: we do not know whether AWS have their own data model
Gunnar: Ted is in the process of organizing a meeting with Patrick Bleicher who is now with AWS
Stephen L: On the device side Greengrass Core, which has local AWS Lambda functions, msg broker etc, can be integrated into higher performance silicon components. There is also Greengrass for FreeRTOS focused on lower power MCU. It has things functionality like Greengrass discovery and MGTT agent.
Stephen L: AWS team maintains a Yocto layer to ease integration of Greengrass into Linux distributions in github https://github.com/aws/meta-aws
Stephen L: look also at https://github.com/aws-samples/meta-aws-demos. There was an integration of AWS into the AGL demo a couple of years ago, more to look at in this repo
Philippe: would like to put the topic of AWS in the agenda of next Monday's call, Unknown User (kevinval) would this be ok ?
Kevin : agreed

Fosdem

Philippe: presents the Fosdem CfP and the rationale for submitting and delivering a talk there, the CfP is there

- Philippe: why don't we ask for a presentation in early 2021 ?
CCS-111 - Getting issue details... STATUS
- Philippe;: why about adding Geotab GoDevice as a possible source of vehicle data ?
- Ulf: Geotab works currently on a new tool that converts the Geotab "address space" to the VSS "address space".
- Gunnar: could it be open source code ?
- Ulf: yes, it might be open sourced, but it is intended for cloud use not for embedded use
- Gunnar: will add this comment to the ticket - Geotab signal input device collection to VSS translation is under development. This code might be more cloud than embedded-focused, but keeping a lookout for it as potentially reuse as a kind of vss-feeder.
CCS-156 - Getting issue details... STATUS
- Gunnar: the Geotab code is coming out
- Glenn: engineering has completed the preparation of code and doc, code will reside on geotab github and genivi github will point to it, the code will be published under MPL2.0

review of tickets assigned to Benjamin & Sebastian & Gerald
CCS-109 - Getting issue details... STATUS
- Sebastien: there is no vehicle state storage in kuksa, it is a digital twin within the car taking info from CAN and talking VSS to the cloud, the online use case with data streaming is implemented using MQTT (actually a subset of MQTT)
- Sebastien: we are now working on the data collection use case using the web socket interface for collecting a batch of data and upload it to Amazon
- Gunnar: reminds Sebastien about the mqtt paper produced by the CCS project a while ago, Sebastian Schildt please have a look at CCS-143 - Getting issue details... STATUS , paper is attached to this ticket
- Sebastian: the code of the demo by Bosch at the GENIVI AMM is available at https://github.com/eclipse/kuksa.val <-- Reuse THIS
- Philippe: it might be worth looking at what could be reused in the Bosch demonstrator for the next version of the demo, ticket CCS-184 - Getting issue details... STATUS created
CCS-171 - Getting issue details... STATUS , CCS-173 - Getting issue details... STATUS

CCS-138 - Getting issue details... STATUS
- Philippe: we need to sync with Bosch on the Digital Twin Description
- Sebastian: I fully agree with the fact we need to sync on digital twins
- Gunnar: IMHO the question is where do I search from the current correct values of the vehicle data (even if there is a disconnect iwth the car)
- Sebastian: there might a twin in the cloud and a twin in the car
- Sebastian: I can reach out people from Bosch involved in Ditto project and put them in contact with whoever in CCS team is willing to look at Ditto
- Philippe: CCS-138 to be closed because Bosch delivered a presentation on digital twins at the AMM, look at Bosch slide deck

sprint review

Augment Vehicle Data Model
CCS-170 - Getting issue details... STATUS Benjamin presents his findings
- vehicle motion interface specs mostly describe ADAS systems, a lot of stuff we are not interesred in (physical laws), describe some sensors and actuators, raw signals and intermediate signals, some systems are pretty simple, please look at Benjamin's comment in Jira
CCS-173 - Getting issue details... STATUS Benjmain presents his findings
- this work is much closer to what W3C is doing (REST interface, json payload on http), it is a top down hierarchy, with metadata, containers and subcontainers, there are some common elements with VSS sections, e.g. start time, end time, etc, iso description of map section ids
- the message structure is pretty interesting, some links to ISO standards for time and location and good practices, this looks similar to we need in VSS to contextualize the vehicle data we define
- please look at Benjamin's comment in Jira
Benjamin: it would be good to get an example of a json payload defined by Jaspar
- Philippe: there are two more documents to review, assigned to Unknown User (benjamin_klotz) tentatively, please confirm you can have a quick look at them
  - CCS-172 - Getting issue details... STATUS
  - CCS-171 - Getting issue details... STATUS
Philippe: IMHO it would good to add a topic on gap analysis between Jaspar and VSS in the CCS working session, the rationale is that Toyota said they will identify someone for the CVII session at the upcoming AMM, we should also invite this person to the CCS working session
Gunnar: this is a good proposal, we have work to do to identify overlap and gap both for VSS vs. Sensoris and VSS vs. Jaspar, I will update the working session content accordingly

tech summit preparation - abstract for the working session

the proposed abstract text is below
it is expected that the agenda for the CCS working session will be derived from the text below and augmented with whatever topic needs to be addressed
"The current GENIVI work on data-driven connected vehicle software architecture is an important step towards achieving the seamless coupling of the in-vehicle and back-end architectures and delivering an end-to-end vehicle computing platform. This end-to-end platform leverages existing standards and solutions, but some gaps exist and overall interoperability is still far from achieved. We are convinced the GENIVI work will help the automotive industry take a big step toward the future when the in-vehicle software, E/E architecture and the back-end architecture will be moving closer together.
The Cloud & Connected Services (CCS) project team has undertaken during Q2, 2020 the implementation of an end-to-end vehicle-to-cloud communication framework proof-of-concept demonstrator. This framework incorporates technology components identified by various collaborative projects such as W3C Gen 2 protocol built on VSS2, GraphQL, ISO Extended Vehicle Neutral Server. It clarifies connections to in-car technologies such as AUTOSAR-defined SOME/IP and several others.
The CCS project team will present a status report of the CCS proof-of-concept implementation and explain the design choices made. The following topics will be also comprehensively debated:
- how to augment the vehicle data model, collaboration with the Sensoris project (www.sensoris.org)
- discussion on which APIs and components on the proposed architecture are candidates for standardization, the objective is to enable an open market for the software components of the communication framework (components are either in-vehicle or in the cloud)
- discussion on how the CCS project will contrbute to the newly laucnhed work on a Common Vehicle Interface (CVII)."

Wednesday 2020-09-02

Recap of implementation plan and status.

The plan/status table in CCS Reference Architecture - Work Breakdown Structure is a bit outdated (wrong(?) responsibles, wrong plan).
It still needs a bit of an update. For now taking the notes here.

In Vehicle Server : still W3C_VehicleSignalInterfaceImpl

State Storage : Implemented by statestorage dir in ccs-w3c-client
Connection vehiclesever to statestorage is in ovds client / server in same repo

Demo Goal

Vehicle/OEM cloudside

- Data collection into state storage by driving the simulator around
- Gen2 server support get/set and subscription
- (Subscription using timer should work, but is not change triggered yet)
- OEM Cloud: Vehicle client can be set to send requests on a timer. Using a file to list signals.
- Stores data with timestamps into database
- Aim for signals that can be graphed
- How to visualize? Grafana. First approach integrate with sqlite according to current schema.

Neutral-Cloud-side
- Swift app with GraphQL client (mostly exists)
- Fetches data from GraphQL server in OEM cloud (server not yet started)
- Shown in a iOS application
- Easiest to go directly to OEM cloud for this demo

Remaining work:

Integration OpenDS to statestorage (Gunnar)
- Define the signals that we expect to have (from OpenDS) --> Swift App can use
!! GraphQL to OEM database integration (?)
Grafana investigation and integration (Gunnar?)
+ "Fake" data feeder for Electrical Vehicle related signals
- list of signals need to match OpenDS is delivering
packaging/testing, preparation
(Optional) Subscription hook on new value / change - make server aware

Side tracks:

Consider using influxdb instead in cloud (database optimized for time series data)

sprint & backlog review (on data modeling related tickets)

CCS-53 - Getting issue details... STATUS
- Possible follow-up with companies who are active in Sensoris, or more official Sensoris-representative to confirm our conclusions, and progress the data-catalog question.
- Gunnar: I'm considering extending https://at.projects.genivi.org/wiki/display/DIRO/Value+measurement+formats with the idea of values tied to a GPS position, similarly to timestamp.
- The data items that are transferred, this still ties to the question of merging data catalogs into a single one (into VSS tree format) – still open question of sorts.
- The definition of their Envelope, Message format, is useful for the particular position-oriented model and hard to reuse generally.
CCS-156 - Getting issue details... STATUS
- Glenn gives an update on discussions on licenses. Detailed paperwork coming so that we can review.
CCS-125 - Getting issue details... STATUS
- Glenn answers during meeting:
  - Standard APIs - primarily VSS would help, but also the programming interface (Geotab SDK provided to companies/users of the platform) would likely benefit from being a more standard interface to achieve better interoperability in the industry.
  - Comparing architectures, would like to review it a bit further internally first.
  - In-vehicle to cloud, efficiency is key (cellular costs). Transformation to shared formats can be done in the cloud, once the data has reached that point.

Gunnar: makes a recap on CVIM discussion, Gunnar Andersson please update the slide you showed, thanks
Keith: who is the OEM active in W3C ?
Ted: JLR
Keith: what is the service catalog about ? VSS is about the data acquisition
Ted: JLR is proposing something to GENIVI & W3C for the command side (service catalog)
Ted: please have a look at https://www.w3.org/2020/03/26-auto-minutes.html#item05
Keith: I heard quite a few OEMs would not get on-board a command API, their concerns is that if you have an API, here are also the parameters on the command, and it gives your IP away from this knowledge, I have been pushed back
Keith: OEMs even described which functions they do not want to be visible
discussion on proprietary vs. non-proprietary model items
Keith: Autosar define their own internal stanfards (for application component APIs) but the architects of the vehicle projects did not use them because they consider it is too much effort
Keith: OEMs love standards for off-the-shelf ECUs and sensors but not for internal work
Gunnar: there is an ability to have private branches in VSS, they could be positioned as VSS Extensions
Gunnar: currently we name everything as VSS, it might be worth thinking about differentiating the naming of the data model and the tooling and the spec langage
Kevin V: IMHO it is a little bit tricky to make a common service API
Gunnar: shows an example of a service catalog from the github repo, we use same words and features as Franca
discussion with Kevin on the service API, for instance the function turnonheater
Kevin V: approach has changed in order to make no assumption on how an OEM intends to implement the control of a function, a signal group is used then for this purpose

  This has been done as a best practice and to follow the Extended Vehicle architecture. However for the PoC it makes to simpify. What is needed is an API component that exposes the GraphQL server externally to Neutral Servers and 3rd parties. This component has to take care of querying the requested data from the OEM cloud database as well."

Vehicle data simulation

Stefan W and Gunnar had a sync meeting on the vehicle data simulation earlier today, this simulation approach could be used jointly bu the CCS and AASIG projects
Stefan's raw notes
- "Learning from Ulf input: VSS to DB Adapter is “flattening” the vss tree structure to be easly stored in the database. The code is available https://github.com/GENIVI/ccs-w3c-client
- For usecase: querying min, max, avg value of the property – not in scope for graphql queries for Data Server Historical values not needed that is why we do not need to have complex database, unlike CCS more relies on data storage.
- Topic to discuss for tomorrow AASIG call ?: Do we consider relying not only on cached/stored/updated values in database updated periodically by vss feeder or foresee the need of “on demand” requesting the fresh data.
- This 3 ways of accesses are not considered as vss leaves def, but might be specified using VSS Layers. Then VSS feeder/Data Server (discuss on the role) can act accordingly (use cached or request for fresh value).
- To reuse VSS Feeder across CCS and AASIG PoC demos agreed the following: Temporarily descope “on demand request of the fresh data from sensor/ecu): Use sqlite as database for storing vehicle properties, then all three parties could write/read from it in common way (w3cgen2 + Apollo grapqhl + vss-feeder).
- Flat the structure of VSS tree to a unique key in the database (like using a string containing full tree path to leaf as a key).
- Tasks to be added to the backlog: Rework current vss-feeder and Apollo grapqhl resolver to use sqllite to retrieve/store data
- Ulf Bjorkengren I guess similar task needs to be performed on w3cgen2 side as well"

GraphQL generation

Below comments are extracted from CCS-96 - Getting issue details... STATUS updated by Kevin
- Client with example queries have been created in Swift: https://github.com/highmobility/vss-graphql-client-swift. Based on this we should see if the VSS GraphQL schema should be modified to simplify 3rd party usage.
- High-Mobility is now waiting for VSS pull request related to Electric Vehicle signals to be reviewed and merged. Then the GraphQL schema can be generated and used for the EV use-case 3rd party service.
Gunnar : it is good to have anoter component to be added to the set of components

NiFi

Sanjeev will look at other ways to transmit data from the cars to the OEM cloud, we have no idea whether it impacts the architecture we have yet

MQTT

Gunnar: MQTT handles only the way you describe the topics and the subscription to those topics , but the payload content is not defined, it is not a major work to do in my opinion
Gunnar: MQTT is popular, should on the list of TODOs for the future
Gunnar: I will write a mapping doc from VSS to MQTT, please add this to the backlog

proof-of-concept implementation status

Ulf: Gen2 crash is solved, it is possible to run the entire VSS tree into Gen2 server and populate the datalake

virtual tech summit - topics for the CCS workshop

each topic will be introduced with a short slidedeck to fuel the discussion
topic #1 - Generation of vehicle data
- Ulf: in the demo, we transport data from the gen2 server to the data lake, but we transport only dummy values, how to integrate something underneath : vehicle simulator or real vehicle data
- Gunnar: one possiiblity is to download a vehicle simulator and "drive a car around" to generate data, how to get people signing for this ?
- intro slide deck owner: Philippe
topic #2 - Technology options for bringing vehicle data into the system
- Gunnar: IMHO we need to investigate other technologies than Gen 2 for bringing vehicle data into the system
- Gunnar: we should think about some use cases and produce some criteria for future decisions
- Gunnar: we will need to scale up the system and measuring its performance, example of options: Web style protocols, coding optimization
- intro slide deck owner: Gunnar
topic #3 - Interface between the datalake and the neutral server and the third parties app
- Ulf: one could discuss what needs to be done above the datalake from "the datalake to the upper left side" of the high-level diagram
- Philippe: we need to realize that this interface is perhaps the easiest to start with analyze for a possible standardization, because the righ side of the high-level diagram (from the vehicle to the OEM cloud) is currently largely based on proprietary solutions
- intro slide deck owner: Kevin V ?
topic #4 - privacy expectations
- Ulf: got some feedback on the terminology like data lake, in a privacy context, data lake has a negative vibe
- Gunnar/Philippe: agreed in particular because we claim we are ISO Extended Vehicle compliant meaning we have "privacy-by-design"
- intro slide deck owner: Gunnar
topic #5: data exchange formats
- Gunnar: since we will likely have attendees that do not follow the day2day work, it is important to disseminate some of the results of our work
- one key opic is the data exchange formats
- slide deck owner: Gunnar

weekly sync with Sanjeev on the client implementation

Participants

Sanjeev, Benjamin, Gerald, Gunnar, Philippe
apologies: Ulf

Minutes

Sanjeev: client was committed on github, I have one issue with the Gen2 server that crashes when (too) many requests are sent
Sanjeev: I have other thoughts about the technologies (e.g. NiFi) we could use for implementing the clients, when should I start looking into these ?
Gunnar: we need to get the current implementation you made running first
Gunnar: I do not have root access to the Gen2 server, so I cannot help for the debugging, I would be good to package this component according to the approach used in CCS-arch-demo repository
Sanjeev: I agree it makes sense, I will package everything in a docker container once the crash issue is solved
Sanjeev: explains what he can show as a demo for the upcoming Virtual Tech Summit

proof-of-concept implementation status

Ulf: I helped Sanjeev to install the go build system today
Gunnar: I also had some trouble with the go building
Ulf: next week I should be able to run the client and do a demo
Gunnar: will there be a command line client ?
Ulf: no the client will go through the complete VSS tree and check for changes, it will work as an infinite loop asking for more data from the data lake
Gunnar: IMHO it might be useful to have a command line interface as well
Gunnar: I tried to build the data server and has some issues with the dependencies
discussion with Ulf on how to set up the datalake and populate the database content
we need to double check the MIT licence since we are modifying code for implementing the ccs-w3c-client DONE MIT license is fine

Minutes

AW webinar slide deck review

Kevin V shares the draft slide deck for the webinar
in-vehicle OS slide (look at the block diagram on top of this page)
- discussion on in-vehicle protocols
- Keith: DDS is also a protocol adopted by AUTOSAR, DDS is an ARA::COM binding as well as SomeIP is, to be added
- ROS is build on top of DDS, ROS and DDS have "topics" and "fields" inside topics
  - look for instance at https://istkb.adlinktech.com/article/overview-dds/
  - other link: https://index.ros.org/doc/ros2/Tutorials/Topics/Understanding-ROS2-Topics/
- discussion on ROS2 (look at https://index.ros.org/doc/ros2/) and open source project autoware (https://www.autoware.org/)
  - autoware is based on ROS
  - look also at https://gitlab.com/autowarefoundation/autoware.ai
  - there is no ROS2 integration in AUTOSAR
  - Apex.ai has joined AUTOSAR as an associate member
    - look at https://www.apex.ai/apex-os
    - apex-os is a rewrite of ROS2 in particular to comply with ISO-26262
utilization of VSS for vehicle data modeling
- Keith: IMHO VSS is a "target" format
- Keith: autoware has its own message definition
  - look at https://gitlab.com/autowarefoundation/autoware.ai/messages/-/tree/master/autoware_msgs/msg
- Keith: since you are promoting VSS as the data modeling language, you have to be prepared to answer a question like how VSS compares to or builds on autoware messages or whatever
slide deck review will continue in an ad-hoc call on Wednesday 29 morning

Kevin V, Ted, Ulf, Keith, Gunnar, Philippe

Minutes

graphql schema example

Gunnar: Alex (BMW) is still waiting for a colleague to review his example before publishing it
Kevin: shows the tool chain Gunnar and he proposed to go from VSS2 to graphql schema, look at the model transformation workflow attached to CCS-96 - Getting issue details... STATUS
- grey boxes corresponds to the open source implementation of the neutral server components that High-Mobility will provide
Kevin: explains the workflow and also a possible alternate workflow from VSS2 to 3rd party client (i.e. w/o going through the neutral server)
Kevin: for the demonstrator we will focus on the EV charging datapoints in order to show attractive use cases
discussion on the data packages and distance w.r.t. the data structures used by CVIM and Sensoris
- CCS data packages (look at the high-level architecture diagram here) should be generic enough so that they can be mapped to any specific project data structures
Ulf: this format does not fit very well with Gen2, IMHO this is not seen in the Gen2 protocol transfer, but rather in the OEM cloud
Gunnar: The picture does not show it used for the transmission to the cloud but in the vehicle only. The format might be used in the car, or not... but I think it is OK to indicate the idea of this would be there (to support historical values). The format is not fixed yet, it needs to be refined further
Gunnar: the in-vehicle state storage could use SQL but might also not need it (it is a simple key-value if not multiple time stamps are stored).
Kevin: I will document which format to put for which version of the proof-of-concept in the wiki
/TODO/ Kevin V to document which format to put for which version of the proof-of-concept in the wiki

PoC design & implementation

Gunnar: shows the code repo structure in github, CCS-arch-demo repository
- repo names correspond to the actual implementation used
- please look at the various readme files
Philippe: jira will be structured according to a list of generic components corresponding to the HL diagram
Gunnar: explains how docker could be used to package each part (SW components) for development help, or maybe for production, e.g. CCS-arch-demo/tree/master/docker/sqlite repository
- shows the OEM-database implementation using SQLite
- shows the test files
- will continue to package the components according to they become available
Gunnar: the next step is to program the create table command for the datalake from Ulf
Ulf: I started implementing the datalake using SQLite
Ulf: I talked to Sanjeev and I will implement a framework around the datalake and expose an API that the client will use to interface with Gen2
Gunnar: what will be the type of API between the vehicle client and the datalake
Ulf: I am actually working on a server that both the client component and the resource management component can use for accessing the datalake, it it written in REST
Gunnar: I am wondering what we will get from having REST APIs between those components, I am wondering whether there could be something simpler
Ulf: IMHO this is simple enough
Gunnar: both Sanjeev and you are working in Go, aren't you ? If one part was done in a typical web language like node.js I could see how a REST interface might be easier to consume. But especially with the same language other communication methods likely exist.
discussion on how to make interfacing simpler
Ulf: we might reconsider this later
Gunnar: it seems to me as some extra work, but we will see it soon then if it is almost done now anyway.

Webinar & virtual summit workshop content: gathering of topics

Kevin: I will present how we came to the high-level diagram for the poc, @Gunnar : will you introduce VSS Gen 2 ?
Gunnar: agreed
Gunnar will be useful to give the full roadmap
Philippe: proof-of-concept roadmap is as follows
- milestone 1 - Spring virtual technical summit (12-14 May)
- milestone 2 - internal milestone (early Q3 - July ?)
- milestone 3 - Fall All Member Meeting, Leipzig, Germany (last week of October)
- milestone 4 - CES 2021, Las Vegas, USA (early January 2021)
Kevin: will show also an overview of the gap analysis
Kevin: draft slide deck for the Webinar will be shared with Gunnar and Philippe to-morrow DONE

projectization in Jira

Philippe: Jira database will be structured with generic components corresponding to big boxes of the high level communication framework diagram

Monday, April 20 - Vehicle Data

Agenda:

Data Categories, VSS tree update with EV signals
Value measurement formats
Sprint & backlog review
AOB

Participants

Kevin V, Ted, Ulf, Gerald, Guru, Benjamin, Keith, Gunnar, Philippe

Minutes

Data Categories, VSS tree update with EV signals

Gunnar: I did some polishing of the page Data Categories
Philippe: what is the status of CCS-89 - Getting issue details... STATUS ?
Ulf: I pushed a PR on VSS github repo at vehicle_signal_specification/pull/154 repository, that contains EV signals coming from Geotab doc on EV data access requirements, then this on the maintainer's side now (Daniel Wilms, BMW)
Philippe: fine with this, we can close the ticket in CCS backlog

Value measurement formats

Gunnar: goes through the latest modifications he made and through Ulf's comment at the end of the page
- CCS-91 - Getting issue details... STATUS
Gerald: it is a side topic maybe, can we discuss in the future the anonymization of the vehicle ID ? in C2C they provide temporary IDs and change it every 5mn
Gunnar: update the "vehicle identity" definition in the wiki page online
Philippe: what is the status of CCS-93 - Getting issue details... STATUS ?
Gunnar: in the value measurement formats we have similar concepts as in CVIM and Sensoris, we need to check what maps to what
Ted: Sensoris is part of the Geospace consortium (OGC.3c work), AFAIK Sensoris is not technically aligned (tbc)
Gunnar: Unknown User (benjamin_klotz) can you help us do the mapping between the value measurement formats and the Sensoris spec ? ideally we should share the same names and perhaps the same content
Benjamin: I can do that both for Sensoris and CVIM as well
CCS-93 commented and changed to in-progress
discussion on Gen 2
Gunnar: I am not sure Gen2 needs to integrate the value measurement formats
Ulf: IMHO most of these should be outside of gen2
Gunnar: shows the "Protocol does not (yet) cover all variations of data exchange" bullet point of the section "Relationship to Protocols" of the wiki page
Ulf: however some data structures shown in the value measurement formats should be added to a gen2 client if the client needs historical data (Ulf Bjorkengren please review here and below)
Ulf: my proposal was that if a node supports historical data you can have metadata in the tree
Ulf: we need to discuss this in the Gen2 group
Ted: how does an application register and sign up to use data (this is related in my opinion to the best practice work in W3C ) ?

Sprint & backlog review

CCS-88 - Getting issue details... STATUS reminder for Keith
CCS-82 - Getting issue details... STATUS
- Gerald: no need to analyze this use case further, sub-task converted to issue and sent back to the backlog
CCS-73 - Getting issue details... STATUS
- Philippe: browses through the wiki page 5GAA related papers for cloud & connected services
- Gunnar: the ones at the top are more relevant that than ones at the bottom, who is interested to read the article of V2X ?
- Philippe: will these papers influence our work to some extent ?
- Gunnar: it might be interested to look there for the use cases for the demonstrator, so far we have not been so clear on what we want to demonstrate
- sub-task converted to issue and sent back to the backlog
CCS-62 - Getting issue details... STATUS done
CCS-5 - Getting issue details... STATUS
- look at Gunnar's comment above on the use cases for the demonstrator
- CCS-70 - Getting issue details... STATUS

PoC design & implementation
Webinar & virtual summit workshop content: gathering of topics
AOB

Participants

Kevin V, Ted, Ulf, Gunnar, Philippe

Minutes

graphql schema example

Kevin: my colleague is working on a graphql example
Gunnar: shows the content of Alexander's graphql file, althought this has not been uploaded by Alex on github yet
Gunnar: not sure of certain statements in Alex's code, I need to check with him
Ulf: the representation in the example seems a little bit redundant with the VSS tree represenetation
Gunnar: the question is that this representation might be useful when used with graphql tooling
Kevin: will the tooling be shared ?
Gunnar: I assume so
Kevin: it is nice to have this example available anyway
Gunnar: FYI Alex is working independently from Daniel, we might have two complementary visions eventually
Gunnar: then shows the very basic graphql example used by Stefan in AASIG VHAL

PoC design & implementation - please refer to C CS Proof-Of-Concept - Work Breakdown Structure

Gunnar: suggests Ulf translates the slides he presented last week into a set of SQL instructions
Philippe: IMHO we need to change to a implement and build mindset now
Philippe: we need to think about the minimal demo we will show in one-month time at the virtual tech summit mid-May
Ulf: it would be good to connect the data lake, the vehicle client and the data server (look at the proof-of-concept block diagram)
Philippe: invites Ulf to join the Monday call with Sanjeev
Gunnar: shows the vehicle client implementation VehicleSignalInterfaceImpl he tried out
discussion on the feature set for the mid-May demo
Gunnar: timestamp is enough (please refer to the wiki page Data serialization / value formats)
Kevin: do the language or platform we use for the PoC implementation matter ?
Gunnar: my proposal at this stage is that this does not matter, it is easier to do that way

Webinar content preparation

Gunnar: AW Webinar is a Webex based, the speaker has a special view

Wednesday, April 8 - Communication Framework

Agenda:

value measurement formats - review
PoC design
- formatting layer
- authentication
graphql schema example
AOB

Participants

Kevin V, Keith, Ted, Ulf, Gunnar, Philippe

Minutes

value measurement formats - review

Kevin V : explains the comments he made to the wiki page (look at the bottom of the page)
Kevin V: we need such a protocol to be defined, the content of the wiki page is very advanced
Kevin V: sensitivity level - an example of such an attribute is driver's fatigue (high) vs. engine oil level (low)
Gunnar: thanks for your very good feedback
Gunnar: the container is some kind of top level messaging format
Gunnar: I tried to work out a type hierarchy with subtypes
Gunnar: we should think that the content of the wiki page comes down to a generic protocol definition that could be instantiated into several actual protocol specifications
Gunnar: the W3C Gen 2 protocol might not take over all the facets of the generic procotol as it is defined there, but if we can align on some definitions and naming with W3C it would be good
CCS-81 - Getting issue details... STATUS done
Philippe: did you have a look at the description of formats ?
Ulf: not yet, however since I am very Gen2 centric, I would say the formatting layer lies on top of Gen 2, using Gen 2 as the transport mechanism
discussion continues of the position of the formatting layer in the CCS PoC
quick check on the sprint & backlog
- Philippe: the cross-checking w.r.t. CVIM and Sensoris is to be performed next
- CCS-4 - Getting issue details... STATUS , subtask CCS-93 - Getting issue details... STATUS unanimous consent to reassign this ticket to Benjamin because of his former work on CVIM and Sensoris

formatting layer in the proof-of-concept

Ulf: the formatting layer is not visible in the vehicle, if the Gen 2 client sits in the cloud, this will sit on top of the client
Ulf: Gen 2 is agnostic w.r.t. where the client is deployed, the client could be in the vehicle or the cloud, in the CCS PoC the client is in the cloud
Ulf: I ambition this formatting layer to sit in the cloud in the CCS PoC
Ulf: concerning jobs, there could be specific jobs where you have some particular logic to implement (TBC likely not captured accurately, Ulf Bjorkengren please check)
Ted: I also see a gen2 client app residing on vehicle and *pushing* data samples to the cloud, I see more of push than a pull, this is an equally viable architecture
Ulf: agreed, design choice might depend on the data (transmission) cost (TBC likely not captured accurately, Ulf Bjorkengren please check)
Gunnar: for the push scenario, will that be using the set function ?
Ted: I would rahter use the subscribe function (TBC likely not captured accurately, Gunnar Andersson please check)
discussion on how to use Gen2
Gunnar: I try to determine if we can solve the use case with the current Gen2 or with an extension of it, set might not be appropriate today
- @Ulf: you are driving the strategy for feature growth in Gen2, would you propose the support of time series in Gen2 ?
- Ulf: yes, I would, it is relevant but perhaps not as an integrated part of Gen2, my view is that it should be outside Gen2
Ted: for the push scenario, look at https://www.w3.org/XML/EXI/, this technique can work for both XML and JSON, this technique is used for the management of large data distribution (e.g. for a fleet of vehicles)

authentication in the proof-of-concept

Keith: I have a question about the authentication, we did not discussed this yet
Keith: we need to discuss how to update the authentication info, I have in mind the use case of the service garage
Gunnar: we need to check whether the proposed architecture should be enhanced to take into account the service garage use case
Gunnar: this has to do actually with the role-based protocol discussed in W3C; in W3C it is assumed currently that the access to data is granted based on a role
Gunnar: in W3C work, by transport protocol we think at something like TLS, you have a certificate checked in TLS to certify you are accessing a certified OEM cloud
Keith: it might be worth documenting the assumptions
~~/TODO/ Gunnar to update~~ CCS-22 - Getting issue details... STATUS accordingly, DONE

graphql schema example

Kevin V: we are working on it
Philippe: AASIG VHAL team is about to publish an example of a graphql schema

WATCH OUT: next Monday call (12 April) is CANCELLED due to Easter break

Monday, April 6 - Client Implementation, Vehicle Data

First call - Asia friendly time 11:30am CET

Agenda

weekly sync with Sanjeev on the client implementation

Participants

Sanjeev, Gunnar, Philippe

Minutes

proof-of-concept design

Gunnar; presents the refinement made on the component interface last week, in CCS Reference Architecture - Work Breakdown Structure
Gunnar: we are now collecting proposals for graphql schemas
discussion on impact on Sanjeev's workitems
Sanjeev: in my opinion, we might need someting like an object store for the data lake
Gunnar: Ulf is likely to propose a relational data base
Philippe: Ulf will make a presentation on the data lake in this afternoon CCS call
Sanjeev: is there any reason to use a relational database ? I saw the data coming as a continuous data stream, unless there is a need of classification of data, I am wondering why we should use a database
Gunnar: understood, in the long run, the name data lake means there could be very diverse data and it could make more sense to look into an object oriented database for instance
Sanjeev: I stumbled in similar problems in the IoT domain
Gunnar: we might go to Hadoop in a later version of the proof-of-concept

client implementation

Sanjeev: last week worked with Ulf on fixing the Gen 2 server, we have a permanent node for the server provided by MIT, this took all the time I could spend on the project
Sanjeev: do I have permission to create a repo in GENIVI github ?
Gunnar: do we create a separate repo for the client ?
Sanjeev: in my opinion, the W3C server module will be become a submodule of the CCS client I will be working on
Gunnar: goes to github/genivi/ccs-w3c-client repo created, Sanjeev set up as admin of the repo

Second call - US friendly time 16:00 CET

- AW webinar

Participants

Ulf, Keith, Kevin Valdek, Ted, Michael Ger (Cloudera), Stephen Lawrence, Gunnar, Philippe

Minutes

Data Lake proposal

Ulf: shows the following slide deck
slide #2 - VSS data lake = VSS tree with data over time and VINs
- Michael: will this be done dynamically ?
- Ulf: let answer your question later
slide #4 - VSS DB table structure
- VIN table is the main entry key
- how many tables will be generated ? actually quite a few table
- at least more than 500 TV-nodes : 500 000 tables might cause a performance issue
- this is why I changed the design to an alternative DB structure
slide #5 - alternative DB structure
- # of tables is proportional to the # VINs
- might be a better design, need to get the opinion of a database expert
- Michael: might get this reviewed by a DB expert
- Keith: with one VIN table, performance wise it should be ok, storage wise of course this is different
slide #6 - database definition
- Ulf: we should not put the VSS path in the database, because if we change the VSS tree, we will have to spread the change in the DB
- Ulf: a simplification of the tables is possible
- discussion on the matches and data retrievals (not captured)
slide #7 - workflow to retrieve data
- Ted: I am wondering whether people wull use a traditional relational database, IMHO we need to get the opinion of Adnan and Benjamin on the database technology selection (i.e. in relationship with the graph server)
- Gunnar; we are very early in the implementation, we are not at the point to reach any conclusion on the database technology to use
- Philippe: mentions Sanjeev's comment on using object oriented data base
slide #8 - deployment in CCS proof-of-concept
- Ulf: I have already developed 95% of the VSStoDB adapter
slide #9 - how to develop / publish this
- Ulf: my intent is to small modifications in the VSS repo for storing the VSStoDB adapter code
/TODO/ Ulf to ask opinion of Adnan and Benjamin on the VSS data lake design proposed in the presentation

Value measurement formats

Kevin: review is still on my todo list, will provide feedback on Wednesday
Ulf: same

Kevin V, Kevin de Sousa, Keith, Ulf, Gunnar, Philippe

Minutes

Communication Framework PoC - moving into implementation start

vehicle client
- Philippe reports on the call with Sanjeev (Samsung) (on Monday this week)
- Ulf: talked to Sanjeev, the two of them will team to work on the vehicle client
in-vehicle OS
- Philippe reports on the call with Bosch (on Tuesday this week) about the possible reuse of components from the Kuksa project
- Sebastian Schildt: Kuksa focused more on the in-vehicle stuff
- Gunnar: this was our expectation
- Sebastian cannot commit to deliver software to GENIVI with any deadline constraint, however he could offer
  - a Kuksa target board (1 or 2 samples) which is based on Rasperry Pi and can be plugged to the OBD
  - this OBD feeder could provide some sort of VSS feeder or a lower part of the VSS feeder that could be accessed through Web sockets
- Tom said he is working on an infrastructure similar to CCS for the eBike project demo, there might be a cool alignment with CCS to look at. He will get back to us.
detailed design
- Gunnar: shows the UML diagrams he added to the CCS PoC wiki page, these diagrams represent the relationships between some of the components of the OEM cloud and Vehicle OS subsystems
- Ulf: it is a good start, it makes things possible
- Ulf: I am ready to talk about the SignalStore and specially with the Bosch people if they are ready to talk about it
- Ulf: I thought about the data lake today, I will come with a proposal on next Monday likely, with a presentation, based on the use of a relational database like SQLite
- Kevin V: the UML diagrams shown are for the vehicle interface, how do we describe things on the neutral server side ?
- Gunnar: in my opinion the UML diagrams could be almost the same for the neutral server to OEM cloud interface,
- Kevin V: the dependency would be the API definition of the OEM cloud (relates to the graphql schema)
- discussion follows on the grapql schema content, how the VSS tree is represented with it ?
- the team agree they need to develop their own understanding of a graphql schema
  - /TODO/ Kevin to take sample yaml code of VSS and transform it into a graphql schema
  - ~~/TODO/ Philippe to ask Alex whether he can share the graphql he is using with Gunnar~~ DONE
next step
- Philippe: expects the team to move now to the actual implementation of the first version of the PoC to be shown mid-May at the virtual technical summit

Data categories

Kevin V: added a couple of comments to the wiki page Data Categories, comments are reviewed
discussion on the container entity proposed by ISO ExVe standard
Kevin V: will paraphrase it the container description to stay on the right side of IP
Kevin V: the container is for the car owner a way to understand for which set of data an OEM ask the car owner for his/her consent
discussion on the naming of entities, some scoping necessary
/TODO/ Gunnar to update the Data Categories wiki page according to Kevin V comments

How to instantiate the big picture on different vehicle EE / Cloud architectures

Philippe: this topic has been in the backlog for a while
- on the vehicle EE side, we need to determine whether we intend to connect to an actual vehicle bus (e.g. using a OBD device or through Ethernet and an Adaptive Autosar ECU, etc.)
- on the cloud side, we need to think about the deployment of the communication framework on an infrastructure like AWS using for instance AWS lambda to expose the graphql APIs (https://aws.amazon.com/lambda/)
- we need to determine in which versions (i.e. milestones) we want to show the deployment on an actual automotive embedded platform and a cloud-based service infrastructure
- Philippe: will add this into the Jira backlog

Dissemination - Automotive World Webinar

Philippe: GENIVI has an opportunity to deliver a new Webinar in the Automotive World Webinars series
short discussion on whether to deliver it before or after the upcoming virtual tech summit
(added offline): Mike N (marketing manager) already blocked a timeslot on the 4th of May
Kevin V is interested in helping for the preparation and delivery of the webinar

- Asia friendly call

Participants

Keith, Kevin V, Ulf, Benjamin, Gunnar, Philippe
apologies: Guru,Gerald, Glenn

Minutes

review of the Geotab document on EV data access requirements

Benjamin: shows a document comparing the content of the Geotab document and the content of the Data Categories wiki page
discussion on use cases vs requirements
Ulf: the Geotab proposal does not propose the current charging power, but only the accumulated power, Geotab is more interesting in the energy than the power (one is the integral of the other overtime anyway)
Kevin: the biggest difference between the Geotab doc and what is is in the wiki is that Geotab is interested more in aggregated data resulting from some data analysis than in the raw data, IMHO we need to update the data categories with Geotab inputs
/TODO/ Benjamin to update data categories with Geotab inputs, CCS-24 - Getting issue details... STATUS commented and assigned to Benjamin
short discussion on the updating of VSS tree with EV signals, based on the comparison made by Benjamin
/TODO/ Benjamin to identify a few VSS signals that could be added to the VSS tree, CCS-89 - Getting issue details... STATUS created and assigned to Benjamin

value measurement formats

Gunnar: shows the modifications of Data serialization / value formats wiki page he made since last Monday call
Keith: remark on VIN number vs MAC address
Gunnar: I use here the VSS defined VIN
Gunnar: details the record types and subtypes
Ulf: do you envision this to be on top of Gen2 ?
Gunnar: this should be on top of every single protocol we want to use
Ulf: agreed, Gen2 is one protocol (the only one for the time being)
Ulf: IMHO this translates partially into subscribe requests on Gen2
Gunnar: yes, the subscribe request is close to what I explained here
Gunnar: my expectation is that all participants this wiki page and check whether the naming of the various items described is appropriate
Ulf: I will look into this, CCS-91 - Getting issue details... STATUS created
Kevin: likes it a lot, it is a very comprehensive set of definitions, are these definitions independent of the data models ?
Gunnar: yes
Kevin: CVIM & Sensoris touched this a little bit, job and streams are a litthe bit independent from the other definitions
Ulf: Kevin pointed out a very crucial thing, how do we structure the storage in the cloud VSS tree, we need to complement the values with time dimension & VIN dimension ?
Ulf: it is quite complicated to come up with the best solution
Gunnar: agreed, this is not trivial
Kevin: it is good to define various layers like time series, etc.
Gunnar: we need to analyse how this work can influence the definition of the database schema
Gunnar: any volunteer for the review of this ?
Kevin: I will look at it, CCS-92 - Getting issue details... STATUS created
Gunnar: I will look into Sensoris and CVIM afterwards
CCS-90 - Getting issue details... STATUS created for tracking the update of Data serialization / value formats wiki page

communication framework

Philippe: Gunnar and I had a discussion with Sanjeev (Samsung) about the vehicle client implementation, Sanjeev was informed of the roadmap until CES 2021
Sanjeev: will start on the vehicle client implementation in Go and should be able to show something for the GENIVI Virtual Meeting in May
Philippe: objective is to start the implementation work this week

Kevin V, Kevin de Sousa, Keith, Gunnar, Philippe

Minutes

W3C virtual meeting - CCS presentation

Gunnar presented the CCS projet in the W3C virtual meeting which is happening this week
OEM attendees provided a very positive feedback on the CCS PoC block-diagram: "this CCS work is right in the middle of what the industry needs"
we might get additional support for developing the PoC and make it a reference implementation
recommendation is to decouple all boxes of the block-diagram as much as possible so that there is no vendor-locking for OEM customers, all parties should be enabled to pick up their own boxes and implement them according to the standardized APIs

Communication Framework PoC - WBS update

continuation of the review of CCS Reference Architecture - Work Breakdown Structure, wiki page updated online
component #1 - in-vehicle storage
- the selection of database is perhaps to be shared with AASIG VHAL project
component #2 - in-vehicle VSS2 translation (a.k.a. VSS feeder)
- we need to set up a call asap with Bosch to determine what could be reused from Kuksa project and to discuss the model transformation tools (VSS-to-Franca and Franca-to-ARXML)
- /TODO/ Philippe to contact Bosch (Sebastian and Christian) for setting up the call asap
discussion on the simulator that might be used to feed simulated data in the poc
- Keith: presents shortly the LGE simulator
  - the simulator is based on unify and can be run using ROS and be interfaced with AutoWare (https://www.autoware.org/) and Apollo (https://github.com/ApolloAuto/apollo)
  - the simulator provides driving itineraries corresponding to big chunks of San Francisco
  - the simulator needs to run on a very powerful desktop, it might be appropriate for a CES kind of demo
- Philippe: the LGE simulator could be an option for the milestone #4 of the CCS PoC (demo at CES 2021)
- Gunnar: what do you mean by interfacing Apollo ?
- Keith: you can run Autoware or Apollo to enable the execution of open source ADAS stacks
component #4 - OEM cloud - vehicle client
- there are several options for this implementation
- curl scripts proposed by Gunnar are only a plan C or higher for the implementation, other options are to be analyzed first
short discussion on open source licence
- Keith: would prefer Apache 2.0, MPL 2.0 copyleft is much too strong for the automotive industry (e.g. vsomeip used by Adaptive Autosar demonstrator)
- Gunnar: currently, we are doing our shopping list for the poc based on existing components
- Gunnar: it is only if new components are developed and hosted by GENIVI that the question of the open source licence needs to be analyzed, anyway GENIVI has a list of "green" licences and is not limited to MPL 2.0 if necessary
component #8 - OEM Cloud (Resource Management =) Data server API
- Gunnar emailed Adnan (BMW) and Daniel (BMW) to get some clarity on their GraphQL work
- Philippe: Alex (BMW) showed the work on GraphQL he did for the AASIG EDS PoC yesterday, his work might also help with this

Next steps

Philippe: we need to start thinking about the identification of APIs that could be standardized
Gunnar: we are at a very early stage, i.e. first iteration of the PoC, the identification of APIs will take time and several PoC iterations
Gunnar: I would propose to start a design justification wiki page for the poc where we can capture the rationale for selecting the components (currently the number one criterion is that the component exists)
Philippe: reminds about the following wiki pages Big Picture & Design concerns that might contain some useful inputs
Gunnar: there is this wiki page Vehicle data exchange protocols
Gunnar: I have also created the following wiki page Data serialization / value formats, the content was reviewed with Unknown User (benjamin_klotz) during Monday's vehicle data call and then augmented, it would be good you read it
/TODO/ CCS participants to review the wiki page Data serialization / value formats
Philippe: next week we need to go through Jira and do a sprint review and we need to kick-start the implementation work

Monday, March 23 - Vehicle Data

Agenda:

review of TODOs
- /TODO/ all CCS participants to review the Geotab document on EV data access requirements
- /TODO/ TBD (Benjamin ?) to compare Geotab doc on EV data requirements and the content of the data bundles wiki page
- /TODO/ Rex to review the Adaptive Autosar signal-to-service specifications

Participants

15:00 CET call: Benjamin (W3C), Gunnar, Philippe
16:00 CET call: Keith, Kevin V, Guru, Philippe

Minutes

First call

discussion starts on the EV data access requirements
- /TODO/ TBD (Benjamin ?) to compare Geotab doc on EV data requirements and the content of the data bundles wiki page
- Philippe: brings clarification on his expectation concerning data categories vs EV data requirements sent by Geotab
discussion continues on the definition of data bundles as described in the wiki page previously named Data Bundles
- Both Gunnar and Benjamin agree to rename the page as Data Categories
Gunnar: in his opinion, it is now important to start looking into the format for message values
Gunnar shows the wiki page Data serialization / value formats he drafted
- review of the definition section of this proposal
- Benjamin: agrees with the definition of a signal
- Benjamin: for the record item, he would rather use observation or measurement
- discussion of examples for a record, with timestamp attached and possible additional information
- there is the special use case of streaming where you have a continuous connection: look at the stream item
discussion continues on data format requirements for the different types of signals
wiki page updated online by Gunnar, look at Data serialization / value formats

Second call

/TODO/ all CCS participants to review the Geotab document on EV data access requirements
- Philippe reminds this TODO to participants, Kevin will look at Geotab document this week
/TODO/ Rex to review the Adaptive Autosar signal-to-service specifications
- Philippe asks Keith (who knows well the Adaptive Autosar stack) whether he could provide an overview of the signal-to-service specifications to the CCS team
- Keith: will do, CCS-88 - Getting issue details... STATUS Jira ticket created for tracking
sync on the communication framework
- Keith was able to join today after a long period of overlapping between CCS call and other calls that prevented him from joining
- Kevin: for the sake of synchronizing Keith with the CCS current status of work, Kevin presents the CCS PoC as described in CCS Reference Architecture - Work Breakdown Structure
- Keith: asks how we can get the gps position of a fleet of cars using the communication infrastructure proposed in the poc
- Kevin V / Philippe: we might have different variants of the poc depending on whether we simulate the vehicle data or we use existing devices like the Geotab Go device if we want to connect to actual cars
- Philippe: for the vehicle simulation, two options have been discussed in the GENIVI AASIG project which is also working on a poc : either using the vehicle simulator published by JLR on GENIVI gitub (genivi-vehicle-simulator repository) or using opends
- Keith: indicates that LGE Labs in the Silicon Valley have also a vehicle simulator
- Philippe: although we will start with laptops as execution targets for the poc, we might switch to automotive boards for the in-vehicle segment of the poc in the future, FYI Renesas has set up a lava-based test farm (with R-Car boards) to build and run the GENIVI CI process, we could use the test farm to simulate the vehicle segment
- Keith: FYI Adaptive Autosar has decommissionned their test farm and runs the CI process on qemu only
- Philippe: invites Keith to the second call of the week which is dedicated to the communication infrastructure

Communication Framework PoC staffing & WBS update

Philippe: reminds that it is now time for the team need to pick up some of work items for the CCS PoC implementation,
- link: CCS Reference Architecture - Work Breakdown Structure
- wiki page updated online by Gunnar. Thanks !
Ulf: I can take over the data server, and its connection to the state storage in the in-vehicle OS box, I am also interested in the data lake
Kevin: we can provide sample applications for the 3rd party service and neutral server marketplace boxes, i.e. entities that will consume graphql apis
Philippe: what about the OEM cloud box ?
Gunnar: we need to determine the signals and the use cases we want to show
Kevin V: we should show different data categories including big data chunks
Kevin V: showing anonymized data is not really possible because this requires a lot of data, it would be better to show different categories
short discussion on the demo use cases
Philippe: explains the use cases selected by the AASIG for the PoC demo (EV data, speed & tyre monitoring and air conditioning
need to add the use cases definition work item
Gerald: I might be able to pull in someone in the in-vehicle OS box , I will ask Sebastian and Christian whether they could recycle something from the kuksa project for the state storage
Gunnar: we need to agree on the format for storing values, e.g. time stamps and values of different types
Gunnar: I would like to get an example of a query for getting multiple snapshots of vehicle data in order to make graphql shine a little bit
Kevin V: if you look at the state of the vehicle, you have a benefit of using a graphql query (get multiple data in one query)
Kevin V: it should also possible to push data with graphql
discussion on the protocols between boxes
Gunnar: I am still waiting for an actual schema for using graphql from someone
Philippe: what about Geotab / Canada ?
Kevin S: I am still chasing what GENIVI is doing, I see myself in a support role rather
review and update of the owner column in the WBS table
Ulf: someone else has to take over the vehicle simulation
Philippe: execution targets will be laptops for the initial implementation
Vehicle client
- vehicle client: Sanjeev's work does not seem to be directly reusable
- Ulf: the client would be repsonsible for stoting the data into the data lake
Data lake
- Gunnar: concenring the data lake, do we have a database person in the call ?
- KevinV not on my side
- Ulf: this is where we should try to get BMW in, it won't be a good idea to invent our own database structure
- Ted: their solution is based on VSS/VSSo too, trying to get Adnan to present what he showed at last W3C F2F
- Gunnar: I talked to Adnan yesterda
OEM cloud
- Gunnar: what the resource management is all about in this box ?
- Kevin V: resource management comes from the extended vehicle ISO standard
- Gunnar: can we replace this naming by "data server apis" in the OEM cloud
- Kevin V: agreed
Neutral Server market
- Kevin V: it is important that we consume data coming the OEM cloud (server) api
Miscellaneous
- Gunnar: I could likely take over the vehicle client and the graphql and data base
Test farm
- Stephen: I checked the use of lava farm for running the CCS poc, do you want to use a RTOS in the in-vehicle OS box or linux ?
- Gunnar: we can plan for this at a later time, The PoC will be linux-based including the in-vehicle OS box
- Philippe: however Renesas could an Adaptive Autosar demonstrator stack in the in-vehicle OS box, this would be good for the demo, it will still be linux-based because the Adaptive Autosar demonstrator is based in RT Linuw

Gunnar: is looking at the splitting the Jira ticket CCS-24 - Getting issue details... STATUS as expected

Bosch Vehicle Abstraction Layer - relevance for CCS

Gunnar: summarizes the discussion with Bosch that happened last Wednesday
Philippe: reminds the rationale for having a discussion with Bosch (which is organizing a workshop on vehicle abstraction at the AMM)
Gunnar: there is a need to unify the industry around a so-called vehicle common interface model, I do not know whether we need to mix the data driven like VSS and the vehicle API
ULf : VSS is good for data decription, service description needs to be added to it, there is also a need to analyze how to map the VSS signals (using the VSS terminology) to whathever is below, ie the different automotive buses
Ulf: I know thar BMW and Volvo have thoughts about this
Gunnar: would be happy to get the correct contacts at Volvo (VCC) to pursue this discussion with them
Ulf: someip to VSS is exactly what VCC has done, Peter Winzell is the one to talk to, he might convince VCC to share some of the work they did

communication framework

Gunnar: shows the CCS PoC WBS
Gunnar: aks Sanjeev for clarification on the work he is doing on the so-called clients
Sanjeev: I limited the scope of my work to the W3C demo shceduled un a couple of weeks time
Sanjeev: I implemented http and websocket connections for the Tizen watch, we have now the vehicle dashboard on the watch, the java scripts used in this implementation are quite straitghforward but need to be rewritten for better clarity
Sanjeev the watch code is in the app store, but I intenf to publish the code as well, the web interface is avauable is the daemon folder, the watch interface is pretty much a html interface
Ted: Magnus from Melco set up the Gen2 server instance on MIT cloud host, the app could point to that
Ted: has set up a Gen2 server instance for demo purposes
Ulf: this data server is up and running, it is available but the link to it has not been released yet
Ted: link is https://www.w3.org/auto/wg/wiki/Vss_data
Sanjeev: back to the clients I am developing, I want to separate the library interfaces from the UX
Gunnar: we need to figure out an idea of the demo we want to do, we need to major progress on this actually
Kevin V: there is a lot of different use cases, that could be used to demonstrate the PoC
Gunnar: we can work with simple queries, but it owuld be good to have simple queries moving a lot of data in odrer to learn abour possible bottlenecks in our communication framework proposal
Benjamin: we could reuse what we have introduced in the data bundles
Rex: do you have at Geotab a document listing all the telematics data ?
Glenn: I am not aware of it
/TODO/ TBD (Benjamin ?) to compare Geotab doc on EV data requirements and the content of the data bundles wiki page
Ulf: asks whether Gunnar can present the CCS PoC block diagram in next week's W3C virtual meeting
Gunnar: will do

graphql

Gunnar: I need help from anyone who is familier with it
Gunnar: we have a limited set of metadata in VSS, VSS is not following a graph and I ask people who proposed graphql what their vision is all about
Benjamin; graphql in theory works with graphs, it does not perfom as well with trees and taxonomies
Benjmain: in the case of VSS, you have VSS tree and you look at signals that are spread over the VSS tree, you define schemas for this purpose
Benjamin: if you want a more complex relationship between signals, the computation you need will be much higher
Benjamin: please have a look at https://graphql.org/learn/schema/, for querying and pushing data regularly graphql is appropritate
Gunnar: Example ?
discussioon on how to represent the vehicle data structure
Kevin V: do you mean nested relationships ?
Gunnar: yes for instance
Gunnar: I would appreciate some hints about graphql
Ted: Adnan could present some stuff on graphql related to vsso and the graph project, to be followed by Gunnar

Vehicle data model enhancement

CCS-77 - Getting issue details... STATUS
- Glenn: Geotab EV division drafted a paper containing the EV signals, e.g. charging information, discharge of the battery, etc. when combined with gps and timestamp this data set can solve all the use cases like range vs destination, upcoming load for the charging station, etc., should be published within some days
CCS-79 - Getting issue details... STATUS
- call with Bosch happened on 11 March, debrief is at the agenda of Monday 16 March call

data contracts & data categories

CCS-24 - Getting issue details... STATUS
- Gunnar: data categories and data contracts is rather a tool than a result, relates to access control, this topic is also being discussed in W3C
- Ulf: we are talking about data categorization and VSS layers but I cannot see the link between both
- Gunnar: there are 2 ways of representing the categories in the layer concept, VSS layer is a format to represent the data categories
- Ulf: discussion data catzgorization is different from representing the categories for instance using the VSS layer data format
- Gunnar: access control group is one example of data category (TBC)
- Gunnar: data contract is something different
- Ulf: it is a fuzzy concept for me
- Gunnar: I can see the connection, I need to check the Geotab's presentation in W3C team about it
  - the presentation is available there
- Gunnar: we need to have common terms on contracts, technical and commercial parameters
- Rex: when you talk about QoS, do you have in mind protocols like DDS and Some/IP (signal-to-service), ARA::COM, some of the building blocks may be there
- Philippe: asks Rex to review the signal-to-service requirements in ARA:COM
  - CCS-87 - Getting issue details... STATUS created
- ~~/TODO/ Philippe send to Rex the Adaptive Autosar signal-to-service specification~~ DONE
  - look for the following requirements: RS_CM_00004 in RS, and 7.5.2 in SWS (the SWS section is the significant reading)
  - https://www.autosar.org/fileadmin/user_upload/standards/adaptive/19-11/AUTOSAR_RS_CommunicationManagement.pdf
  - https://www.autosar.org/fileadmin/user_upload/standards/adaptive/19-11/AUTOSAR_SWS_CommunicationManagement.pdf
- Ulf: who are the two parties in such a contract discussion ?
- Gunnar: could be the OEMs and the neutral server companies
- Kevin: data providers = OEMs, there is a contract between the neutral server and the third parties (data consumers), the neutral server does not change much the content
- Gunnar: we need a framework / template to write those contracts
- Gunnar: we need to set up a framework for access control
- Kevin: applying data categories to data contracts is the real pain
- Gunnar let separate those two wordings and check whether the industry wants to progress on both topics
  - /TODO/ Gunnar structure better the Jira ticket in order to distinguish the work on data contracts from the work on data categories CCS-24 - Getting issue details... STATUS
- Glenn: data contracts in Geotab document mentioned above might not fully be appropriate for the discussion we have here
- discussion on what a contract is all about

Communication Framework PoC - WBS

Kevin presents the wiki page containing the WBS
/TODO/ all participants to review the WBS and identify which work item could be taken over
Gunnar shows CCS-11 - Getting issue details... STATUS where he added the list of technogolies that could be used for the PoC
Ulf: regarding the client implementation Sanjeev is doing, Sanjeev will present his work as part of the remote F2F W3C will have at the end of the month, Sanjeev is working on different platforms including an Android app
OEM cloud: Kevin is fine with Hadoop
Glenn: we need to remap the data from different OEMs to a common standard, go back to the data guys and talk to them about the pinpoints
/TODO/ Glenn provide feedback on a possible common standard for next week
/TODO/ Philippe set up a call with Sanjeev and invite him to follow / join the CCS project
Rex: IMHO we could set an Adaptive Autosar stack in the cloud
Philippe: possibly but in my opinion this is for the future, the architecture of the current PoC adresses a mid-term vehicle EE architecture (like the one depicted on slide #4 and marked as "today" of the VAP presentation by Bosch), having an Autosar stack in the cloud corresponfs rather to a future vehicle EE architecture like the one depicted on slide #4 and marked as "smart infrastructure" of the VAP presentation by Bosch

PoC implementation

Ulf: would like to advertize the prototype Gen2 server implementation we do for the W3C group
Kevin: supports the proposal
Ulf: it is not production level but there is a considerable number of functionalities available
Ulf: error handling is not so resilient yet
Gunnar: agreed, we need to put this into the blue boxes of the big picture diagram, blue boxes named data server could be implemented using the Gen2 prototype
Gunnar: graphql is another option that could be demonstrated in a parallel thread
Philippe: VHAL team is looking at graphql implementation
Gunnar: this is an argumen tor CCS to look into Gen2
Gunnar: what about the clients ?
Ulf: we have small clients available for testing the data servers, Sanjeev (former Samsung) is working on clients
/TODO/ Philippe contact Sanjeev
Ulf: would be good to collaborate with the W3C project implementing the data lake
Phil: would be good to augment the big picture diagram (look at diagram V2 in Vehicle data exchange protocols) with the list of work items and technos used and create a table listing the wok items and the assignees like we did
to contributors
/TODO/ Kevin to add link to possible technologies on the diagram
Ulf: we can use for instance https://github.com/MEAE-GOT/W3C_VehicleSignalInterfaceImpl
/TODO/ Gunnar do the same
- CCS-11 - Getting issue details... STATUS updated
- Kevin: we need to determine what we use on the OEM cloud part
discussion on the use of Gen2
Gunnar: let determine who will provide the graphql implementation , maybe BMW maybe myself (I have to put some work into it)
discussion on how to align the CCS PoC project and the W3C Gen2 implementation
Gunnar: we all agree to align projects, what we need are resources
Rex: I have a common terminology question, which translation / transformation are you talking about ?
Ulf: BMW has a large number of cars connected today, they do not use VSS format, they use different proprietary data formats
Ulf: BMW took the decision that once these data are in the cloud, BMW will create the data lake using VSS1 or VSS2 and use graphql to do queries
Rex: wonders whether BMW is using the ASAM standard for describing signals
Rex: how is the topic of data compression approach ?
Gunnar: it could typically be done at the transport protocol level
Gunnar: what do you, Rex, mean by analyzing compressed data ? we have not touched this yet
Gunnar: do we need to start looking into OpenID ?
/TODO/ Kevin initiate the WBS table for the CCS PoC from the example provided here by the VHAL project
- CCS-86 - Getting issue details... STATUS created as a sub-task of CCS-8 - Getting issue details... STATUS

AMM preparation

GENIVI is currently actively doing the AMM content planning, Steve Crumb (Executive Director) is watching closely the virus situation and a decision to keep the AMM physical vs virtual will happen soon

a use case presented by Gerald

Gerald shows this slide (Gerald Spreitz please upload the slide), is the CCS use case APP presented here still what we are discussing in the project ?
Gunnar: what do you mean by: is CCS still supporting this use case ?
Gunnar: at signals level, we can think of signal groups you can get access to
Ulf: W3C Gen2 could be a potential candidate for a large part of this use case, Gen2 supports both on-board agents and cloud-based agents
Gerald: can you clarify what you mean by the grouping of signals ?
Gunnar: tthis is work-in-progress, my view is that there will be many groups because having a fine granularity is key
Gerald: can the granularity be down to one signal only ?
Gunnar: I wrote an example related to vehicle identification for the VSS layer presentation that gives an idea of what I think is an appropriate grouping
Gunnar: we could look a little bit deeper in the design of this APP use case you presented using Gen2

Gerald: thinks about the monetization of this use case, if you do not provide vehicle data you have to pay for the app
Gerald: we should not forget about the commercial aspects in our work

Data set for EV management

Gunnar: remember that data set must rather be called naming of signals
Glenn: this is work-in-progress, expects to have an answer in a week or the rationale for not having an answer and not being able to share the data Geotab use with power utilities
Glenn: what is important is the rationale of the power utilities for using the signals
- CCS-77 - Getting issue details... STATUS commented

data contracts & data categories

Gunnar: shows the data bundles wiki page, reminds about the privacy aspects
Gunnar: the need has to drive the work, we need to work out a complete access control group first before reworking data contracts and data categories
Gunnar: do other think we need to work in parallel ?
Gunnar: elaborates on the EV data the OEMs would like to control the accessibility of (e.g. battery durability relales to warranty cost, etc.), I am sure we will have the mechanisms to handle this
- the data related to this might even not be transmitted because providing those data is not in the business contract
- delivering that data can be done under a contract to specific third parties
Gunnar: we expect to have the mechanism to control the access technically and businesswise
- CCS-83 - Getting issue details... STATUS created, unassigned

communication framework

look at Vehicle Data Exchange Prococols wiki page
Gunnar: presented the wiki page, are the protocols we discuss enough for what we want to do ? he explains his vision of the work to do as described in the wiki
Kevin: explains the differences between the latest "big picture" diagram and the initial one
Kevin: explains he removed the container processing because we use Gen2 now
Gunnar: here are in my the pieces of the puzzle
1. understanding of the big picture
2. protocols between compoments
3. dig into components

Sprint & backlog review

the Jira tracker was renamed as CCS (instead of VCS) and updated, look at CCS backlog
/TODO/ Gunnar to check that the Jira notification scheme is active for the CCS project
/TODO/ All to check the backlog and current sprint content
current sprint is until the end of March
Philippe's expectation is that we will be able to start some PoC activities soon in order to show something at the upcoming Spring AMM (12-14 May)

AOB Privacy

Glenn: the following topic might be of interest to the team _ Privacy and EU
Do you know if the organization (or any of the OEMs) are planning to weigh-in on the following ==> The European Data Protection Board (EDPB) releases DRAFT guidelines for processing of Personal Data in the context of Connected Vehicles - and is open for comment --> Guidelines 1/2020 (Comments Due on March 20th)

Friday, February 28 - Communication Framework

Agenda:

continuation of discussion started in Monday 24 February call (W3C)
how to instantiate the big picture on different vehicle EE / Cloud architectures

Participants

Gerald, Ulf, Kevin de Sousa (partially joined), Kevin Valdek, Gunnar, Philippe

Minutes

Communication Framework - W3C

Kevin checked Gen2
how Gen2 fits in the big picture: both rest and web sockets
explanation of what the CVIM container processing is all about (some kind of buffering), what happens if the connection is lost
Ulf: this is a good point, there is no buffering in the standard W3C work
Ulf: this requiement has not been put on the table in the W3C team, maybe we should raise the point in W3C, what do you think about it, Gunnar ?
Gunnar: I an more on the solution mode than the standardization side, the container holds the measured values, there are a couple of design options
- you can build a function in the protocol itself and request the sequence of data points for the last hour for instance
- you can also reuse VSS to represent a sequence of signals
- you can also consider a pre-processing of the signals like an histogram in the car, i.e. on the edge, there is some metadata to be transfered to achieve this
Gunnar: we need to identify the boundaries of the W3C protocols and how we can complement / augment this work
Kevin: in today's implementation, the signals are lost (no memory of the sequence of signals), if we assume there is a value storage in the vehicle, we could perhaps send a request for giving the rpm for the last 3 hours
discussion on the data update process, ask for instance for the min/max data for the last couple of hours
Ulf: there is a possibility to use the query we have introduced in Gen2 for such a purpose
Ulf: go the filtering section (gencore.hmtl), you can search more than one node, you can also add metadata, in this context, it is possible to add some functionalities like the one we discussed before (with a time dimension)
Gunnar: it is possible for an OEM to override the metadata of a signal

Next step

Gunnar: we have some work to do to design the functions that we want: min/max, histograms, etc. and look how we can implement these, either in the query language or in the metadata
Gunnar: we need to gather the requirements ar the feature level
Ulf: Geotab has a pattern / method we use for "friends" to minimize the data we keep, the computation draws straight lines between points, we use this method for all data we send from the embedded devices we use
Gunnar: it sounds that we need a new wiki page describing the data processing features needed
~~/TODO/~~ ~~Gunnar to initiate the wiki page~~ DONE: Vehicle data exchange protocols
/TODO/ Kevin to add an update version of the big picture diagram and the description of some components

Minutes

Data set for EV management

KevinV: the data set is not complete and some parties do not want to share all details
Gunnar: You mean the OEM not wanting to share some of the detailed EV data
Gunnar: Note that we discussed separating the standardization from the obligation to deliver the data.
- The standards _enable_ data sharing between partners.
- Agreeing on actually delivering the data is more of a business contract.
- We can work on a business framework to enable this
Gerald: Are there any standards for the agreement on which data is delivered ?
Kevin: Yes some consent discussions exist but standards are not quite there yet, implementation of connected EVs is not widespread
Gerald: But do proposals exist ?
Kevin: Only what is mentioned in Extended Vehicle, to my knowledge (not a lot of details)
Gerald: So is this an open point to study, for CCS project?
Gunnar: Yes it could be but for me some of those places where this might apply will naturally "fall out" of further work on the architecture (meaning let's progress the technical architecture a bit
more and maybe later the opportunity to fill those gaps come up)
Kevin: (A more important) missing thing is consensus on what type of data is required for (thid party) features, what actually needs to be shared, to enable a particular service.
Gunnar: So it ties into data categories and also access control groups might give some of that picture.
Kevin: Agreed.
Glenn: (So it's about) data requirements per use case. EV is a good one to start with because for other vehicles connectivity is a nice to have. For EVs it is critical, i.e. know where charging exists, and how/where vehicles exist and where charging is expected to happen (demand for capacity)
Glenn: Therefore keep progressing the minimal set of data for EVs first.
Next (added offline by Philippe): there is a need to complement / rework the description of the work items on data contracts and data categories in Jira
- look at CCS-24 - Getting issue details... STATUS

Discussion on vehicle abstraction layer.

Several people missed this presentation last week.
Gunnar: I at least need another round with Sebastian to fully grasp what we really mean here.
Gunnar: In my opinion we should emphasize commonality, not differences.
- Work towards that common interfaces and technology should be used throughout the industry, rather than emphasize that common interfaces are needed / because / common technology / standards are NOT used throughout
- I might be missing details but I'm not really comfortable with the "abstraction" idea proposed by Sebastian
Next (added offline by Philippe): there is a need to complement / rework the description of the related work items in Jira
- look at CCS-78 - Getting issue details... STATUS

Communication framework

the high-level block diagram proposed by KevinV is shown
KevinS: brings a clarification on what Geotab is doing today, Geotab runs a sort of container on their embedded device today
KevinS: for an OEM, it might consist in running a GENIVI VSS as a so-called container
KevinS: what Geotab is doing is generalizing the in-vehicle processing with the OEM cloud
KevinS: the communication between the Geotab device and the cloud is proprierary
KevinS: the Geotab communication framework architecture currently is very closed to what is shown on the block diagram, the data processing would be very different on the Getoab side
Ulf: the diagram is quite interesting, but where are the W3C standards mentioned? We see W3C Gen 2 to be also used between cloud and the vehicle
Ulf: since Gunnar is active in W3C and we are trying to standardize the cloud to vehicle interaction, it would be worth showing this to W3C and discussing the transport protocol and the container processing
Philippe: explains the approach taken by KevinS to build to this diagram
Ulf: VISS is the first assumption for the implementaIion, we are now working with the so-called Gen2 in W3C
Gunnar: Let's see if for every place where it says "REST", we can clarify that we mean "W3C Gen 2 REST", (sync with Kevin V to see if this is the case)
/TODO/ Kevin V to look at Gen2
~~/TODO/ Ulf to send the links to Gen2~~ DONE below are some links to the W3C automotive working group.

Keith: what is VSS 2.0 about ?
Gunnar: it only just means "next release". It is not a new concept. For now consider the master branch as the content. Sure, there have been some advancement of the syntax, semantics, tooling and vss-layers, but the "2" is not there to indicate a whole new concept.
Gunnar: clarification brought on how to bring the latest values, VSS define only the isgnals, we need data feeders
Gunnar: querying the data and ask for their values is something that W3C is not looking into yet, the CCS project is going beyond what W3C is doing
KevinV: graphQL is another Web technology; BMW has an interest in it in addition to what Google is doing, explains the thinking behind bringing grahQL in the picture
Ulf: I agree that (the powerful query language of) graphQL is very powerful, it is a perfect technology to work with at the data lake level, however I have some doubt about that approach if you put it in the vehicle,
Ulf: The interpretation and execution of the queries in the vehicle will put equally a powerful load on the vehicle to answer those
Philippe: explains the short term to long term of the vehicle EE (look at slide #4 of the EE architecture evolution, in the long-term, we might afford grapQL on in-vehicle HPC nodes (Hogh Power Compute).
Philippe: The powerful computing nodes in the vehicle might be able to handle it.
discussion on how to instantiate the CCS block-diagram on vehicle EE architectures. Geotab approach with an embedded device might be appropriate for the short to mid term. However CCS architecture draft proposal for the CCS block-diagram should rather be mapped on an architecture like the one of slide #4 above
discussion on communication framework architecture will continue on Wednesday call at 5pm CET.

Minutes

Data set for EV management

Ulf joins today's call following a request made by Glenn, Ulf is in CET timezone, Ulf checked the VSS tree for data related to EVs
Ulf works rather with the structure of the tree and not on the content
- the tree contains many branches, I did a grep on EV data and found only one file called battery management containing data like temperature, charge status, there is also an charging inlet which is an enum that contains values like AC, DC
- in the drivetrain branch , there is an electric motor branch but with no data in it
Philippe: who is in the position to complement the VSS tree ?
Gunnar: complementing the tree is not a W3C process question , we need to spot the identify domain expert to fill the blanks
Ulf: I agree with Gunnar, we need domain experts from OEMs to get the EV branch populated, I asked Volvo (VCC) before (when I was working with them), and got very small success
Gunnar: this needs to get into the tree in order to get things move on with EVs
Gunnar: we will follow up with Sarah (see minutes of CCS call of 10 February) , we can use whatever is available through Geotab devices (connected to OBD port today), since we do not know what is available from the OEMs yet
Gunnar: a key question with the battery data is that OEMs might not be willing to share the data (e.g. battery capacity) that would be related to battery degradation
Gunnar: it would be good to check which diagnostic data on battery we could get
Philippe: what about W3C ?
Gunnar: Ted is willing to get inputs on EV, but our interest is to get this done faster
Ulf: if OEMs are reluctant to bring inputs, we might initiate this gathering by asking Geotab for the data they are used to
Philippe: I will follow-up with Sarah

Kuksa project update / Vehicle Abstraction Layer

Sebastian presents one slide giving the main timeline of the Kuksa projet and the follow-up project called VAL
- Appstacle project is over
- VAPP is an internal Bosch project, we are allowed to share on it, VAL stands for Vehicle Abstraction Layer
- Eclipse KUKSA.val project contains the Kuksa VISS server that was spinned off as a separate component
Then Sebastian shows a slide deck presenting the Vehicle Asbtraction Layer concept Bosch is now digging into
- the slide deck contains the well known Bosch slide on vehicle EE architecture evolution (slide #3) and the next step which is the EE architecture extension to cloud connectivity (slide #4)
- the end2end vehicle application architecture (from back end / cloud services) to domain and zone controller is shown (slide #7)
- a so-called Vehicle Application Plugin Platform is identified that would support the execution of Vehicle Services plugins that run on HPC (High Power Computer) nodes and not and deeply embedded microcontrollers
- one example of a Vehicle Service is for instance the the trunk opening (for putting packages in the trunk), the actual implementation is very different among OEMS, having a trunk opening service abstract description would help (look at slides #8-9-10)
Gunnar: is VSS on the slides ?
Sebastian: VSS was not there because these slides were a teaser about the VAL project (before kick-off)
Ulf: will this work suitable for future VSS work ?
Sebastian: not only one technology is suitable for data abstraction, VSS is one (look at slide #11)
Philippe: do we need more abstraction beyond the trunk lock and trunk electric drive ?
Gunnar: the trunk opening abstraction is something like a programming API
Sebastian: the RPC is an easy question, w.r.t. abstraction, the trunk might be different for a car, a bus or a truck (this last one being very different)
Sebastian: we can play with the Kuksa implementation of VSS, it is good for playing with the abstraction concepts
Sebastian: however we do not intend to push the work we did in ISO (TBC)
Gunnar: I agree that the current state of VSS is not enough to describe a vehicle, the goal in my opinion is that at the end of the road the signals in VSS are actually this
vehicle abstraction layer
Gunnar: the part / model / layer about the trunk opening is a (parallel) project different from VSS in my opinion
Sebastian: agreed, the VAPP stuff is different from VSS
Gunnar: I have no problem with the Bosch big picture and having more programming APIs
Philippe: do you intend to describe the vehicle hardware elements as well ?
Sebastian: we have signals and RPCs but we do not intend to describe the vehicle hw
Gunnar: AFAIK Philippe refers to the vehicle configuration, e.g. in infotainment how many speakers do we have ?
Gunnar: this configuration might be something to add to the VAPP description, what do you think ?
Sebastian: my opinion is that the hw description is given by some sort of tooling whose role is to describe the "ugly part of the system", the VSS fits well for describing the abstraction
we need
Ulf: I agree that the stuff below should be abstracted, IMHO the tree structure used by VSS is also suitable for describing the "ugly stuff below", a few OEMs are using
the VSS tree to link things together, there is the layer mechanism we are using in W3C to organize/abstract the data that helps this work, but it is OEM specific work that can be
added to the framework
Gunnar: this is the proprietary data base that could be added using the same framework
Gunnar: it is very unlikely that OEMs will redefine their CAN signals because of VSS, we will need a translation for those signals, however when we move to Ethernet, we could use VSS to describe the data (PDUs) on the Ethernet networks
Sebastian: so called feeders will push the available data to the live tree representing the car wherever they come from (OBD, CAN, Ethernet, etc.)
Gunnar: IMHO the live tree you mentioned is the data storage used by the vehicle data server
Gunnar: today's discussion is helpful, we are synchronizing our vision of the vehicle abstraction

Communication Framework

Kevin Valdek presents this slide that presents the big picture of the Cloud2Vehicle Communication Framework
this slide was inspired by the work of AASIG project and last week's Geotab presentation
VSS2 is used for the description of the data content
it is proposed to re-use the container concept proposed by CVIM to encapsulate the data (the sample code in the box comes from CVIM)
both MQTT (currently used by various OEMs) and new options (like GraphQL, look at GENIVI AASIG work on the external data server) are used for the communication between the in-vehicle part and the OEM cloud
both REST and WebSocket protocols are used for the communication between the OEM cloud, neutral server and 3rd party service
Kevin de Sousa, Gunnar, Philippe: agree with the architectural design concept for the communication framework preseted
KevinS: the architecture presented is similar to the Geotab vision and platform. We will review it and provide feedback in the next call.
/TODO/ KevinS to review the Cloud2Vehicle Communication Framework big picture and provide feedback for next call
- CCS-62 - Getting issue details... STATUS

Next steps

Philippe: IMHO we need now to derive the scope of proof-of-concept work for the communication framework, we might consider organizing a F2F workshop (or a longer telco) for defining the work breakdown structure for this work
KevinV: my company could possibly provide a contribution on the top left part of the framework ("neutral server marketplace" on the diagram)
KevinV: IMHO Geotab could possibly provide inputs/code for the bottom right part of the framework ("container processing" on the diagram)

EV data use cases : presentation by Geotab & discussion

Sarah is senior customer projects manager in EV fleet management at Geotab and works on smart charging
Geotab has a B2B & B2C smart charging management platform offering
Sarah delivers this presentation
The rationale for enabling smart charging through the monitoring of EV data is that the grid is not originally designed for EV charging and commercial EV fleet operators and power utilities expect to improve the charging operations according to different criteria (hence the different use cases presented)
the consumer use case scenarii (i.e. for passenger EVs) are not distant from the commercial fleet, however there is less maturity in consumer EVs than commercial EVs
DERMS means Distributed Energy Resource Management System, Demand-Side Management is a subset of DERMS
Gunnar: we need to define the vehicle data we need for EV management in the VSS database we use in GENIVI for the vehicle data modeling
Sarah: currently this is no standard wean use and it is a lot of work to do (i.e. to adapt to the commercial EVs our customer use), we are very much interested in standards
Gunnar: you use the OBD-II port, it is a subset of all electrical data available in the car, in VSS the vehicle data set is much larger, the branch for EV data is very minimal
Philippe: do you support OCPP (Open Charge Alliance) ?
Sarah: we support OCPP in our smart charging platform, OCCP is not using a lot of vehicle data, we look at the state of charge in the vehicle only
Philippe: explains GENIVI objective which is to enhance the VSS database w.r.t. EVs in order to be future proof (because ICE part will decrease in the future)
Gunnar: this is why we need domain expertise to identify which data need to be added in VSS for EVs
Sarah: it is not a considerable data set, OEMs have a different level of data than the one we use, fleet managers need less data, the so-called last mile delivery use case is interested in other set of
data, power utilities need only the 15mn average power consumption
Glenn: it is worth noting that with commercial fleet management, the decision making / policy making are focused in the same hands
Glenn: in the consumer domain instead, the decision making is much more distributed, the policies are much more diverse, deploying DERMS is more difficult (or less mature for the time being)
Next step
- Gunnar: we need to look at the current content of VSS and see how it matches with Geotab undertanding of the use cases and required data set
- Kevin: the datasets for EV are very limited because the OEMs do not want to share the information about their battery management (and degradation for instance)
- Glenn: we are in a process of mapping the vehicle data we use at Geotab artefacts to the VSS data but the project is not completed yet
- Gunnar: we need to improve the VSS database if necessary, e.g. to allow third parties to have access to some specific dataset extensions
- TODO Glenn review the current EV branch of the VSS database and check whether the data described there are relevant and sufficient for enabling EV charging management / DERMS

Minutes

Goal setting for the call

Gunnar: which protocols are relevant ? Web protocols (REST), MQTT, NiFi, etc.
Gunnar: what is the rate for transferring the data ? The framework deal with things like when a piece of data needs to be requested in order to meet the caching freshness goals and when the data flow needs to slow down because a certain part in the flow is getting its buffers filled, caching data when the dataflow goes down (management of the back pressure on the protocols) ?
KevinV: this is a good starting point
KevinV: high frequency data cannot likely be supported by REST, because of required refreshing rate, this should be considered in the design of the architecture
Gunnar: we need to mention edge computing because for some data it is necessary to transform the high volume of data, the data can be pre-processed on the edge (vehicle)
KevinV: it is even the most complicated part, how are the data captured and processed ? can we influence this ?
KevinS: everything sounds good, I am comfortable with the discussion so far and can bring experience with other oems in Northern America, there are pros and cons of the different approaches, will a standardized approach be based on edge computing ?
Glenn: Gunnar brought the idea of having a buffer in the vehicle containing some data that can bring to the cloud some time later, going through dark spots of connectivity
KevinS: this is the way Geotab devices are working today, we do memory buffers for the different data we are sampling
Gunnar: AFAIK some data compression can be done by matching data to particular curves (splines)
Glenn: the techno used by Geotab is presented in a 10mn video available on YouTube, I could certainly investigate whether we could push this to W3C
/TODO/ Glenn to provide the link to the YouTube video
KevinS: yes, it is appropriate
KevinV: in the GENIVI CCS project we want to define a framework and if the inputs you just mentioned are relevant, we want the CCS framework to meet this kind of requirements, we should use VSS as well, we would request Geotab to tell the CCS project whether the features identified for the framework are valid

Deliverables

KevinV: what could be the project deliverables ?
Philippe: I agree this is important
Gunnar: we need to describe a technical architecture and the software components in this architecture
Gunnar: it is unknown whether we will get a consensus on the architecture among the industry
Gunnar: we should list all the different users of data and the categories for those data and look at how combining them with the vehicle data
Gunnar: as far as a deliverable is concerned, we could write a white paper, we need to determine how complete we can make such a paper
KevinV: for categories, we have some materials, it would be good to have some technical architecture in place for supporting those categories

Backlog building

KevinV: I can do a rough sketch of the end-to-end architecture and provide a big picture in 2-week time
/TODO/ KevinV draw a rough sketch of of the end-to-end architecture and provide a big picture of the Vehicle2Cloud Communication Framework
Glenn: I like the idea of a whitepaper, Geotab could draft a section of in-vehicle data capturing and processing
Gleen: KevinS could provide some high-level slides on this as well
Gunnar: we need to identify and list the different categories of data users and the rationale for using these data
Gunnar: which data (like environment data) could be merged with vehicle data ?
Glenn: we should take into account the DSRC-based data at intersections, the objective with these data is identify the risk associated with intersections
Gunnar. We need to identify which data are foreseen in V2V/V2X exchanges, I have in mind a paper written by the 5GAA consortium
/TODO/ Gunnar to provide the link to the 5GAA paper describing the data foreseen in V2V/V2X data exchanges, there are several papers on https://5gaa.org
- E.g. 5GAA Releases White Paper on C-V2X Use Cases: Methodology, Examples and Service Level Requirementshttps://5gaa.org/wp-content/uploads/2019/07/5GAA_191906_WP_CV2X_UCs_v1.pdf
Glenn: NHTSA in the US has projects related to this, they have not decided whether the industry will be going be DSRC or 5G
/TODO/ Glenn to provide the links to NHTSA paper on V2V/V2X data exchanges

Next call

It will be likely scheduled on Wed 12 February at 5pm CET provided neither Gunnar and Philippe have an agenda collision in the same timeslot. This will be confirmed

EV charging

Kevin: IMHO EV charging when the vehicle is connected to the charging station is totally in the scope of use cases and specifications defined by a consortium like the Open Charging Alliance. However there is a need to know the status of the EV battery charge when the vehicle is not connected
Glenn: AKAIK the utilities request the status of EV battery charge for load balancing, I could bring an expert in the call to explain the EV/Power Utility communication use case for commercial vehicles as means possible inclusion by GENIVI in defining 'scope' for EV/Electrical Utility communication requirements - leading to the development of open specifications for broaded use of same.
/TODO/ Geotab to provide an expert in this area to describe current use cases at Monday GENIVI call. (5:30 CET)
Benjamin: in W3C VSS, there is a branch on battery capacity but it is empty up to now
- https://github.com/GENIVI/vehicle_signal_specification/blob/master/spec/Drivetrain/BatteryManagement.vspec
Gunnar: agreed, there is a need to complement VSS on this
Gunnar: I agree that when the EV is connected to the charging station, this is not a use case for GENIVI, however when the vehicle is OTA, this is in scope of our CCS project
Kevin: last week we at High Mobility open sourced all of our SDK with a unified set of APIs (based on data we got from BMW/Mercedes/... on the production projects), it might be good to look at data examples available at
- charging data: https://github.com/highmobility/auto-api/blob/master/charging.yml
Gunnar: IMHO we should rename this topic to EV management (i.e. something different than EV charging) since we do not overlap with the work on EV charging
Guru: we need also to clarify how this topic fits with the EV battery management system
EV charging docs (reminder) - useful links
- OCCP: https://www.openchargealliance.org/downloads/
- EV charging ecosystem overview: Electric_Vehicle_Charging_-_Definitions_and_Explanation_-_january_2019.pdf

Communication infrastructure - Platform candidates for the CCS PoC

Philippe: reminds us it would be good to look at Amazon Auto and MS Azure and Veniam (https://veniam.com/products/) as possible target platforms for the CCS project demonstrator
Kevin: does not know Veniam, will check
Gunnar: we need to undestand what role Amazon would like to play: do Amazon want to compete with companies like Geotab and others or do they simply want to sell infrastructure
Gunnar: IMHO it is time to make a generalization of the infrastructure we have in mind
Gunnar: I would like to know whether the car OEMs are already communicating their data through vehicle neutral servers ?
Kevin: we should organize a call to brainstorm on the communication with others
Gunnar: AFAIK W3C process is a little bit slow, we should organize to make faster progress, we need to put building blocks in place
decision schedule a call for brainstorming on communication infrastructure with Kevin/Gunnar on Thu 30 Jan 11:30am CET (ad-hoc call), Philippe will send a calendar invite DONE
(added offline): Geotab proposed to provide an overview of commercial vehicle to cloud services use case as an example that GENIVI may choose to include in TBD scope for vehicle/'cloud services' (e.g. Amazon, Microsoft Azure), and development of applicable open specifications to satisfy such use cases. Geotab will join the ad-hoc call to present this.

Data categories

Gunnar: in order to keep things concrete, it would be good to give an example of data categories for VSS signals
Glenn asks for clarification
Glenn will send a note to Geotab/Ulf and asks him to sync with Gunnar on this
Gunnar: the scope of the work proposed is not the same as what Geotab is doing for the W3C VSS PoC but we could reuse the same set of data
/TODO/ Gunnar follow with Ulf/Geotab on providing examples of data categories for VSS
Keith: aks a question on VISS (not captured, apologies)
Gunnar: will provide a clarification

CES debrief

GENIVI showcase: 1400 people attended it, Gunnar & Philippe stood up in front of the GENIVI projects table, slide decks presenting the deliverables recently published were shown on large TV monitors (automotive virtualization platform specifications, vehicle data models overview, FARACON tool). We had discussion with Microsoft, GM and Ford. Very good feedback from the participants
SAE/GENIVI Connect2Car track: several panels were organized, discussion with Exelon Corp (a US power utility) about creating a WG in GENIVI on vehicle electrification
- first step would be for Exelon to attend the CCS call to discuss the need for vehicle data modeling for EV charging
Transportation Technology track: Philippe attended a session called IoT and AI Revolutionizing Transportation, participants were Veniam CEO (https://veniam.com), VW Automony CEO (VW subsidiary dedicated to Autonomous Vehicle technology), Dell Technologies and a lawyer from the UK&Wales transportation commission (lawyer was specialized on AV deployment). Veniam CEO presented the 5G-based IOT platform they market to support the vehicle connectivity
Automotive Exhibition Hall: among many other companies, Amazon Auto had a big booth there and showed many demos, Amazon Auto booth was crowded

EV charging

docs to look at are the following
- OCCP: https://www.openchargealliance.org/downloads/
- EV charging ecosystem overview: Electric_Vehicle_Charging_-_Definitions_and_Explanation_-_january_2019.pdf
Glenn: power utilities use history of EVs battery charge for balancing the power to supply EVs
Philippe: IMHO it would be good to look at the public specifications for EV charging protocols and data contents and check for their relevance for the work on vehicle data modeling we have done
to be further discussed next week

Platform candidates for the CCS PoC

Philippe: IMHO it would be good to look at Amazon Auto and MS Azur and Veniam (https://veniam.com/products/) as possible target platforms for the CCS project demonstrator
links pointing to Amazon Auto work
- https://aws.amazon.com/solutions/aws-connected-vehicle-solution/?did=sl_card&trk=sl_card
- https://aws.amazon.com/automotive/customer-engagement/
  - Amazon FreeRTOS = OSS
  - FreeRTOS kernel + 'enablers'. Think relationship between Linux kernel and GNU.
  - AWS Greengrass is other end point: https://aws.amazon.com/fr/greengrass/
GENIVI participant from Renesas said Renesas have done various integration projects with Amazon Auto and MS Azur.
Gunnar: Iin my opinion, it is worth looking at these platforms
to be further discussed next week

Communication framework design

Gerald asks about the status of this thread
Philippe: we need to build on the materials presented by Kevin in the related session of the tech summit, look here
Philippe: IMHO our objective should be to refine the end-to-end architecture coined by Gerald at the beginning of the project and determine whether we have variants of the architecture depending on the use cases, we need also to detail further how the access to vehicle data is handled depending on various access policies
Gunnar explains that categorizing the vehicle data is an important preliminary step for the design work
/TODO/ Philippe & Gunnar organize a call with Benjamin on data categorization (on top of VSS) DONE
the call with Benjamin was based on the following slide deck
data categorization will be at the agenda of next week's call

Review of the deliverable:

document updated online
need to add a table comparing the data models per criterion similar to the tables shown by Benjamin at the tech summit on the presentation on data models
/TODO/ Benjamin add the table(s) comparing the data models to the Google docs document
Glenn: what is the meaning of gap ? is the gap between protocols or between the data and the use cases
Gunnar: the gap we have been looking into are more on the gap between protocols (Gunnar Andersson to be confirmed)
Glenn: I will review the document and possibly add the standpoint of commercial fleet management

Data Categories

Kevin I created a wiki page to gather information on data categories, link: https://at.projects.genivi.org/wiki/display/DIRO/Data+bundles
this page is oriented towards the gathering of data categories (called "bundles") and the related use case
/TODO/ all participants add your inputs on data categories in the data bundles wiki page

Minutes

Debriefing of Cloud & Connected Services sessions at the tech summit

Project Charter

Keith: revisiting the project charter would be helpful, in particular identifying the deliverables
/TODO/ Philippe revise the project charter

Data Models

Philippe: in my opinion, it turns out that we can proceed with VSS as the baseline data model
Glenn: VSS is very helpful, there is a need to have a better awareness about having a data model, there is a need to present if in next year's conferences
Glenn: we need to develop the data required by different use cases
Gunnar: we would like to put most of the BMW data model into the VSS work
Glenn: will be bring Ulf who is working with W3C in the conversation
Philippe: could the identification of use cases be done using the ones identified in Kevin's presentation of the communication infrastructure ?
Kevin: yes, use cases are also related to the data categories

Data categories

Gunnar: we need to make categories of data w.r.t. sensitivity of data, privacy, different laws and juridiction
Kevin: I propose to create a wiki page on data categories
Benjamin: agreed it does make sense
/TODO/ Kevin create a wiki page on data categories (for next week's call)

Data aggregation

then Gunnar presents his notes from the workshop
Gunnar: VSM we should look over this project , this is about combining the signals into other set of signals
Glenn: data aggregation is one of the most important use case from our commercial fleet management business
Gunnar: this relates to vehicle-side algorithms to aggregate data

Miscellaneous

Gunnar: there is a need for exchanging (short) video in a commercial vehicle context
Gunnar: it might be wortk looking at the use cases identifed in the 5G whitepaper (several whitepapers listed here, need to find relevant one(s))
Gunnar: when it comes down to controlling a vehicle, specific remote APIs are likely better than data exchange
Gunnar: there is a need to look at DDS
Philippe: this is rather for the GPRO project backlog
/TODO/ Gunnar & Kevin add notes from the tech summit sessions to the page of wiki minutes

System design

Kevin: in this session, we discussed actually more fundamentals questions than the design itself like privacy, authorization, etc.
Philippe: I would recommend we start using the term "policies" when we want to describe the constraints / attrributes attached to a category of data

Data models gap analysis

Philippe: the participants need to review the google doc containing the gap analysis deliverables
discussion on how to bring the doc to completenss
/TODO/ Benjamin write an intro + a conclusion to the doc based on the list of bullet points
/TODO/ Gunnar write the section on Vehile HAL, i.e. on how to connect the Vehicle HAL to the vehicle data capturing infrastructure

- FCA: Philippe will do the follow-up with them
- Ford: Steve will do the follow-up with Ford

Tuesday, November 12 - Tech Summit - Towards a common data model

Partial capturing of the Q&A
slide deck
Geotab - Glenn: gives the example of the lidar sensor that can spot available parking spots, can it be part of the VSS ?
Benjamin: yes, we can model it as an extension
Gerald: from the lidar, you get only a low-level information which is the distance-to-obstacle and if you look at the map, parking spots are not identified, much more processing is required, IMHO it is a very complex example
Glenn: the purpose was to propose a use case outside the transportation itself
Gunnar: reminds the audience about the dynamic agents concept that was pushed by JLR (capabilities to execute some highly-constrained code that can be uploaded on the vehicle)
Keith: question on sensor description, how to push the VSS to an official standard like SAE/ISO or IEEE, how do we get broader adoption for VSS ?
Glenn: we need to do dissemination among more OEMs
FCA: we are looking into this, we are exploring it
consultant: OEMs are afraid to lose their "secret" data, to get better value for the car, we should look at what other in telecoms did, in my opinion, there is a no secret data
Gunnar: we need to understand how to write a contract for a data
Keith: no data is secret, OEMs want to own the data and sell them
X (consultant): telecom industry tried to keep the data proprietary but failed
Keith: reminds the safety critical aspects of data
Keith: why do google move to autonomous driving ? because of the data, Google wants to be in the revenue stream
Y: VSS is a human readable description, OEMs are currently concerned by the telephone bills, is VSS the right modeling approah ?
FCA: data means also taking commands from the cloud to the vehicle
discussion on engineering units
what are the data actually representing the driver's action on the accelerator pedal ? pedal position or pressure on the pedal ?
Benjamin: should we include in VSS the AD(Autonomous Driving) vehicle sensors and the brand new IVI features ?
Alex: I disagree with the way the VSS tree is currently described, I would prefer everything to be described in the vehicle data tree, no proprietrary extensions
X (consultant): we need to push something useful and comprehensive enough to get accepted

Connected Services planning of tech summit

Session One: towards a common data model

Introductory slides and more slides to guide a workshop:
Define overall goal (* of workshop)
- find a common data model
- include questions to trigger discussion
the goal of the project itself should be in the earlier overview presentation, but can be repeated
/TODO/ Keith review the CCS project charter
Outline from before:
- starting from the data in the vehicle
- VSS intro, AA Vehicle HAL intro
- Report on the gap analysis (Sensoris, etc.)
- Need for consolidating the models: Ask OEMs & participants about it
Anticipate and think about answers to questions/concerns that come up: (Many new people, some might start from scratch with this standardization idea)
- Hard to standardize on CAN signals
  - (find useful subset (already exists in diagnostics),
  - => discuss the need for standards on the developer "API" level anyway.
  - VSS can be used on CAN/network level but also on the higher levels.
  - => Discuss the need to minimize (but maybe not eliminate) data translation across network -> local apps -> cloud → data/statistics users
- Someone might ask: Does the work cover remote Unlock car, start engine, and similar functions?
  - =>There is definite resistance to this. Discuss reasons why? Is it security concerns?
  - => Do open specifications have a (negative) relationship to cyber-security ? Prepare answer on this.
- Keith: IMHO we need to explain we do not look at the downloading of data from the cloud to the vehicle, just upload of vehicle data, it might help breaking some resistance to the standardization of an upload link
- Concerns about that standards may be linked to OEMs being forced to give away data
  - -> A controlled (standard) approach will allow handling this likely better than a "wild west"
- CCS can focus, if participants prefer, not on not only technical standards but also anticipate a framework for the commercial contract setups that control the actual live data that is exchanged at any time. In other words: Technical standards are not equal to the data exchange itself
How to define data items is not the same as the actual data (sensor measurements, user data)
How is access managed?
- => Fine-grained access control for applications and users of data
- Prepare presentation of access control approaches (technical means)
  - => Access control in a Neutral-Server environment (probably input from Kevin)
Before 10:45am-12:15pm (towards a common data model session) there is the project introduction session. Make sure to address some of the concerns there.
- Data on the internal vehicle level is not the same as outside the car. Both have potential for some standardization but can be done on only one of them too.
- How the choice of technical specification can affect the end result (performance, feasibility of ...)
- Policies for future-proofing (new versions of protocol specifications, and of the VSS itself).
- Discussion: What parts of the VSS-based ecosystem is based on a standard database of named signal, and how large parts are proprietary extensions?
  - Example: Oil consumption unit depends on location.
  - Units - VSS has losely specified an approach for this as follows:
    - Prefer international (SI) units.
    - But in some cases non-SI unit is the defacto standard in automotive.
    - And in some cases there are no agreed standards.
- Question: Are there some signals that should allow for more than one unit to be fair to all OEMs ? E.g. km/h and miles/h. Some that have a preference extremely strong in some markets? Notable, drivers are in different countries so on the user HMI level, car manufacturers already do a lot of conversion to local preferences. So the problem would remain only on standardization on in-car networks
/TODO/ Benjamin, prepare material with input from the above, and we can do a final review next week
- Present Gap Analysis results is also a part of this

Abstract of Session One (for reference)
The GENIVI Cloud and Connected Services project intends to define an end-to-end reference architecture between vehicle sensors and the back-end cloud. Essential to this architecture is agreeing to a common method of representing in-vehicle data. This session will provide overviews of the Vehicle Signal Specification (VSS), used in the definition of the W3C automotive working group. It will look at gaps existing with other data models and in the in-vehicle portion of the architecture, explore data in an Android Automotive context and consider ways of consolidating vehicle data modeling approaches

Session Two: The Value of Vehicle Data to Enterprises., Moderated by Keith (LGE)

FIRST: Keith -- create short intro. (needs input on what the speakers will include, i.e. needs their slides)
Connection to AUTOSAR? Keith is our liaison
Session plan:
- Blueprint for Vehicle-Oriented, Data Strategy (Kevin Valdek, CTO, High Mobility) 30 min?
- Unlocking the Value in Vehicular Data Using Analytics (Amir Sayegh, Geotab) 30 min?
- Can we have a coffee break here? Yes (possibly local to this track) Coffee break - plan for 30 minutes
- Industry Standards for Advanced Vehicle Data (John Schmotzer, Emerging Analytics Connected Vehicle Manager, Ford) 30 min?
- Q&A: 30 minutes,
- Coffee break - plan for 30 minutes
- Total time : 150 minutes
  = total 30 minutes remains for additional discussion time.
- Should be adequate, if we can have the coffee break as planned _before_ the last talk.

Session Three: Capturing Vehicle Data and Communication Framework Design (Moderated by Kevin Valdek, High Mobility)

Kevin is preparing his inputs following call with Gunnar and Philippe scheduled on Thursday last week

Gap analysis deliverable readiness check

wiki page is in good shape, some additional inputs or reviews needed
/TODO/ participants review Benjamin's text on CVIM
Gerald reported that it seems HERE entered also the field of vehicle data and include also the neutral server concept.
- link: https://developer.here.com/blog/open-location-platform-2.8-release
- Access to vehicle sensor data - the Marketplace can now act as a secure, neutral, GDPR-compliant hub for data consumers to gain access to vehicle data from participating Automotive manufacturers
- Consent management - ensures privacy for owners and drivers of vehicles, by allowing them to grant and revoke consent for specific third-parties to access data generated by their vehicles
- ISO 20078 <https://www.iso.org/standard/66978.html> "ExVe" compliant interface - simplifies platform integration for data providers and consumer
- /TODO/ Guru review Here open location platform content and determine whether this is relevant for CCS and has an impact on our work, identify also a list of questions to be asked to the Sensoris project lead during the 2nd call we are considering have with him

GENIVI technical summit - content planning, additional information
- registration link is at https://www.eventleaf.com/TechSummit19ent
- content will be finalized this week, 3 tracks are planned: Connected Services, Android Automotive, Cybersecurity
- quick poll on who will attend
https://grpc.io/: is this relevant for CCS ?
- g stands for Google
- Gunnar: we look at Google rpc in the GPRO project when we did the survey on communication protocols, look at the list of technologies we looked at and the GPRO white paper
- grprc is built on http2 which never took off, people are rather working on http3, gprc is likely well suited on web technologies, it is one of many choices that are out there
- from my perspective, it is relevant but not more relevant than anything else, when it comes to protocols that are not REST oriented protocols, MQTT has more relevance
SAREF Automotive - https://www.w3.org/2019/09/trans-data-ws/SAREF.pdf
- Benjamin reviewed the paper presented at the W3C workshop on data models for transportation, his findings on SAREF automotive are here
- use cases identified in the paper are
  - Platooning
  - Automated Valet Parking (AVP)
  - Cooperative Perception Service (CPS)
  - Vulnerable Road Users (VRUs)
- Philippe: these use cases fit well into the the future, i.e. much beyond a 5-year horizon
- Philippe: IMHO currently in the CCS project, short term is represented by the current High Mobility offering on the market, and the on-going work is rather looking at the mid-term,
- Kevin: it would be good to ask OEMs what use cases are more tangible to implement
Gap analysis deliverable - review feedback of draft sections on VSS, Sensoris, etc.
- Philippe: I reshuffled the pages a little bit and the draft deliverable appears now in the main CCS page table of content, look at Vehicle Data Models - Overview & Gap Analysis deliverable
- Philippe: Guru and Benjamin have provided their inputs, Guru added his inputs in the wiki, I added the link the CVIM doc prepared by Benjamin to the wiki page
- Kevin: I reviewed the draft document on VSS prepared by Gunnar, the intro is not specific to VSS but fairly general
- Gunnar: agreed, we need to ask again for the review work the VSS doc
- /TODO/ Daniel/Benjamin/Guru/etc please review the VSS doc
- Gunnar: I will review the Sensoris section written by Guru
- Kevin: I will review the CVIM doc prepared by Benjamin
- Gunnar: Steve pointed us to two other data exchange standards from the Open Group
- I found them to be mostly similar or related to what OCF might be doing. I also found them to be fairly thin specs in particular O-DM but the messaging standard might have something useful
  - Open Data Format (O-DF) https://publications.opengroup.org/c14a
  - Open Messaging Interface (O-MI) https://publications.opengroup.org/c14b
- We are wondering what OCF think about it:
  - Is it used by OCF or not ?
  - Is it out of scope and covering other unrelated things ?
  - or is it overlapping, but OCF have created other standards to cover this instead ? (It might of course boil down to a simple XML vs JSON preference...)
  - Unknown User (don.dulchinos) Do you have any feeling on how well these standards are adopted?
- /TODO/ Don review these data exchange standards from the Open Group
- Gunnar: we should consider adding some info on SAREF and the Open Group work in the gap analysis deliverable
Big Picture & Design concerns wiki page - more feedback
- link added to the CCS main wiki page
- Gunnar: the topics / issues in the design concerns page should be transformed soon in a set of work items described in jira, Kevin has provided his comments already, other comments are welcome until next week call
- I will also review the existing tickets in Jira that might be relevant to the topics described in the design concerns wiki page
- Philippe: I will projectize this in Jira starting next week
Sprint & backlog review (end of Sprint 4)
- VCS-48 - Getting issue details... STATUS target date for producing the gap analysis deliverable is 8 November, we will present it at the tech summit
- VCS-59 - Getting issue details... STATUS /TODO/ Gunnar ping Michael Ger to get a Cloudera architect into CCS project
- VCS-35 - Getting issue details... STATUS Daniel said he is "back" and should start working on it this week
- VCS-60 - Getting issue details... STATUS /TODO/ Gerald please do
- VCS-6 - Getting issue details... STATUS see above design concerns, projectization will be developed further starting next week
- VCS-61 - Getting issue details... STATUS done, see above
- VCS-39 - Getting issue details... STATUS no news from Sebastian, Gerald Spreitz can you help ?
Enterprise data value: new topic to be added to the project scope ?
- Steve: when I met with Ford last week, one of their concerns was how to make value out of the vehicle data
- this is a gap in the CCS project charter according to Ford and GM perspective
- Steve: it seems to me that these organisations do not fuly understand yet what means a shared platform for capturing and distributing vehicle data
- Gunnar: one of the criticisms we had with the European OEMs concept of neutral server is that the OEMs will control all the vehicle data, we do not understand what the enterprise data value means for for the US OEMs yet,
- Steve: theUS OEMs seem to be looking for which strategic partnerships they need to build for the vehicle data
- Kevin: what kind of uses cases are foreseen , what kind of data rates are considered ?
- Philippe: I would suggest to ask high mobility (Kevin) to deliver a company presentation at the tech summit because HM business in my opinion exemplifies what the enterprise data value is about

Minutes

OCF (Open Connectivity Forum) Cloud Services WG introduction
- Ondrej works for Kitsler, a sensor manufacturing company https://www.kistler.com
- Ondrej shows a slide deck on OCF Cloud WG, Device API for Cloud Services, Cloud API for Cloud Services
- Philippe: IMHO the OCF cloud services are to be added as a possible cloud-based framework for poc development & end-to-end integration in the later stages of CCS project
- Gerald: can we possibly clarify about the mapping of the OCF cloud services to the automotive use cases ? with vendor A = BMW and vendor = GM for instance
- Ondrej : my car is one of the devices, when I sit in my car, I can see my local (home) data
- Guru: is there a limitation on the number of vehicles connected ?
- Ondrej: the implementation is fully scalable
- Ondrej will share the slide deck and the API specifications with GENIVI (how to share these materials with the CCS participants is being checked)
GENIVI technical summit
- Philippe: announces the date and location for the tech summit - Tuesday 12 and Wednesday 13 November, in Troy, Michigan, USA and outlines the tech summit content that will focus on Android Automotive SIG, Cloud&Connected Services and Cybersecurity for the Vehicle
- Steve: has spent last couple of weeks reaching with Ford, GM and FCA, metwith Ford alrealy and will meet with GM on Friday this week and later with FCA
- Steve: the CCS project charter is close to what Ford thinks about where the market is going
- Steve: our objective is to engage those OEMs (and their suppliers) in working sessions about the CCS project
- Philippe: please all of you put a note in your calendar and check your travel plan ! thanks
Design concerns
- Kevin provided his inputs as comments to the wiki page, look at Big Picture & Design concerns, comments are reviewed online
- Kevin: the wiki page is a very good thread opener
- discussion on Kevin's first comment on the protocols, actually rather on the different ways of performing the data capturing from the vehicle to the servers
- Gunnar: on the protocol for Vehicle => 3rd Party Servers, we need to go out and survey who are the players in the industry and which models of data capturing are acceptable
- Kevin: : it's a bit of a different case, it could be brought out separately from the in-vehicle infotainment system to third-party servers, because that's the route the data would take.
- Gunnar: presumably, yes, it is like an app getting a direct connection and maybe we leave that out the scope and say that's not part of our infrastructure. But at the same time in order to cover all cases, we should consider these points, see what they mean for us and see if we can relate to them in some way in our specifications because otherwise companies tend to work around it anyway, and they end up doing ad hoc things that we might be able to avoid if we actually cover it in our discussions
- Kevin: actually vehicle to third-party servers connection comes down to connecting to devices or devices in general like a smartphone, this is the obvious example of having a direct access from my mobile device or an application in a mobile device to the onboard systems, that's more of the typical MirrorLink type of solutions, but it is true there is a lack of data protocols there and if this is VSS that the Vehicle Gateway is using and if these are VSS data that are being uploaded to the cloud, then of course if there is a direct connection with Wi-Fi or Bluetooth from smartphone and the vehicle, it makes sense that the VSS model or a certain data model is used there as well.
- Kevin: One more comment in the OEM server to neutral server part, we should add a connection from OEM server to third-party servers or developers as in general the OEMs will provide an API both for neutral servers who serve as intermediaries and directly to third parties, that's already starting to become a common practice and should be considered.
- Kevin: I have another comment that relates to the question Gerald mentioned with big data earlier, in my opinion there are certain (or maybe even larger) design impacts of the system considering personalized data, which are more like small data chunks with high frequency and high velocity rather than big data type of sharing between two different services. Probably the system block-diagrams are to look quite different at some components level.
- Kevin: in my second set of comments, I added some thoughts about the third-party expectations. This is nothing groundbreaking but more practical things. The callback feature is one thing that third parties expect. Third parties rely a lot on quite up-to-date data. That means that sometimes even one minute old data is not that good because of a business case where you need to act fast on certain data or because of the user experience for instance in electric car charging where you want to get an event as soon as charging is complete.
- Kevin: with the VSS and the W3C, I've seen websocket protocols are considered, and the system design should have (when we have a Rest API or an SDK) a callback system with web hooks, this was mentioned also in the OCF presentation. Today a lot of these OEM systems that do provide data don't provide callback systems in general and it is a bit of a headache for third parties. Typically there are different request limits that can be hard to meet at the same time, if there are no webhooks, it creates a problem because third parties want to get the latest data at the same time and the OEMs might limit them with their request limits because otherwise they get too much traffic to the servers. This kind of problem needs to be solved with technology and should be part of the system design we are considering
- Kevin: in the last two steps of my second set of comments, I added a few things about the fleets. In general with data sharing, there is a general consent from the owners of the car, this is more for personal vehicles, when it comes to fleets, there are different considerations. If a fleet owner has 1,000 vehicles for instance, the third party application and the fleet owner are the same entity, in that case how that is handled and how the data querying is handled probably should be also part of the overall system design.
- Gunnar: I agree with your views, IMHO we should have a list of typical applications / use cases, i.e. something to drive where we need to do different solutions. As you said, the solutions might be different for fleet management applications and user oriented applications. Also what you said about the Big Data statistics being a different one from user-centric data.
- Kevin: agreed, I could add a list of use cases in the wiki page trying to cover some different verticals.
- Philippe: we need to ask again Cloudera about their inputs of the system design for gathering vehicle big data
- /TODO/ Gunnar set up a call with Cloudera to get their inputs of the system design for gathering vehicle big data

Gap analysis
- Gunnar: shares the draft sections on VSS available at this document and asks participants to review it
- Guru: wonders whether building a huge wiki page containing all the sections of the gap analysis is the right approach
- Gunnar: for the time being, in my opinion, the sections for each project should be structured according to the wiki page table of content
- Guru: will finalize the draft sections on Sensoris accordingly in the document he initiated and will call for a review in one day or so

  - https://www.w3.org/2019/09/trans-data-ws/ITS_Data_Model-W3C-2019-09.pptx
  - Gunnar: introduces the slide deck, we should review with the comprehensive web site, the work seems to be fairly USA centric and ITS-related and related to fleet operation, we might be willing to take this into account in our work
  - Steve (who attended the workshop): it was an interesting presentation, consolidation of info from various specs, navigable on-line site with connection through various data models
  - slide 10: shows all data models in scope of this work
  - /TODO/ Bosch review the slide deck and possibly report on findings for next week
  - jira ticket created
  - Towards a SAREF extension for Automotive Michelle Wetterwald, Netellany
  - https://www.w3.org/2019/09/trans-data-ws/SAREF.pdf
  - this work was pointed out by one of the AutoMat project participants interviewed by Philippe late July
  - Philippe: it refers to the work on data ontologies pushed by EU whose motivation is to define and promote an European standard
  - /TODO/ Benjamin review the slide deck on SAREF (TBC), Philippe will ask him about it
  - jira ticket created
  - Don: was VSS discussed there ?
  - Steve not in the workshop because VSS was discussed in a W3C auto WG scheduled the days before
  - Don: what about VSSo work ?
  - Gunnar: VSSowork is led by Benjamin and Daniel Wilms (BMW)
OCF Automotive update
- Don: the OCF SC is still considering doing a demo at CES, there is an OCF interop event planned later this year, theme of the possible CES demo will be ratherabout electrification / charging status in the home
Gap analysis deliverable - review of drafts
- Philippe: Benjamin said it will start working on it on Wednesday
  - Gunnar: before I can start writing my contribution, I feld the need to put down my thoughts on the framework design
  - these can be found at Big Picture & Design concerns that shows the different ways we can think about for the framework design
  - Philippe: I would recommend that you review the architecture and building blocks for the neutral server approach with High Mobility because this is their business and the same for the big data approach with Cloudera because this is also their business
  - Philippe (added offline). Kevin said last week he could add to the initial list questions coming from their experience with 3rd parties at High Mobility
  - Gunnar: we need to spot a technical contact at Cloudera (I will ask Michael Ger)
  - Gunnar: we should also dig a little bit into vehicle fleet data management and impact on the "design concerns" content
  - Gerald: this is what Sensoris has looked into
Sprint & backlog review
- CCS-59 to be checked with cloudera and engineers there
- CCS-35 Philippe will ping daniel wilms
- CCS-6 we should start populating it with work items related to Gunnar's thoughts on software designs, Gunnar: will do that, a link to Big Picture & Design concerns pzge added to the Jira ticket
- CCS-38 /TODO/ @Kevin can you close it ?
- CCS-39 Philippe will ping Sebastien about the status of the Kuksa project

Agenda

Roundtable
W3C workshop on data models for transportation - Debrief (Steve) (skipped because Steve could not attend the weekly call)
Sync opportunity with Autosar (Keith, Steve)
Gap analysis deliverable
AOB
- system design
- OCF cloud WG

Minutes

roundtable
- Keith: LGE has an automotive component division, not quite like Hitachi or Yamaha though
- Keith is the only person working on Autosar at LGE, US, Keith's role is to be fully active in Autosar
- 2-3 months ago Keith started raising the awareness around Autosar in the Silicon Valley
Sync opportunity with Autosar
- during this week's meeting with Steve Crumb, the slides he showed sounded very familiar to me because they were close to what I presented the Cloud Services WG to Autosar sometime ago
- the logical next step is to come with a single standard, in my opinion there is potentially a lot of synergy on the topic of cloud services between the two consortia
- LGE has a particular interest in cloud services
- the possible working mode Steve and I identified would be that Autosar endorse whatever will come out from the GENIVI work

Gap analysis deliverable
- Kevin will make his contribution by Thursday
- Guru shows the (Word) document he is working on for the Sensoris part, he will import it into Confluence soon
- Philippe recommends Guru to maintain a list of questions to Sensoris, we will have an opportunity to pass them over to Sensoris project lead during the second call scheduled in almost 2-week time
- Philippe changed the status of the Jira tickets related to the gap analysis work
  - Gunnar shares the content outline for the VSS part of the document
  - Don asks about the status of VSS work and would like to sync with Ted Guild on W3C work
  - Gunnar suggests to set up a call with Ted
System Design
- Gunnar introduces the proof-of-concept for performing the translation from VSS to Franca to Some/IP, bottom-up works better for me
- Philippe: please look at the minutes of the AASIG Vehicle Data API project
- Gunnar; the question is whether we make direct conversions from data specs (like VSS) to protocol like REST or do we go through Franca ?
- Philippe: in my opinion, we should have a list of open questions
- Gunnar Andersson: /TODO/ Gunnar initiate a list of open questions related to system design
- Kevin: I can add to the initial list questions coming from our experience with 3rd parties at High Mobility

Call with Sensoris
- very good and friendly atmosphere in the call
- Prokop seems to be quite open for a coordination discussion
- He gave a rough overview od Sensoris including business cases and system architecture, business cases are OEM-related and do not intend to provide an open access to the vehicle
- Sensoris objective is to describe what the car is sensing for the world surrounding it, e.g. number of lanes, road works, traffic signals, outside temperatue (as part of a data set called climate, temperature and weather)
- Gunnar: VSS (was described by Prokop as...) focusing more on the in-vehicle data and SensorIS more on modeling the outside world that the car drives through. We have not been through to compare the data models during the call but there seems to be is some overlap in some areas but not in other like map-related data and data with a location-based focus
- Gunnar: License - Sensoris do not permit derivatives (Using CC-BY-ND). It could be interpreted as they are only body that can launch Sensoris specs, but also means that flexible reuse is difficult. They propose openess to anyone who wants to change the SensorIS spec.
- Unknown: "This is the way they work with Japanese projects"
  - look at the CCS minutes of July 22, link to Japanese projects: http://en.sip-adus.go.jp/sip/
- Gunnar: Sensoris welcome any proposal that would make their data model more complete, but this proposal would become part of the Sensoris data model because of their licensing approach
- Prokop shows an architecture picture (that includes GENIVI and AGL as a kind of "technology choices" inside of vehicle. Explanation was made about GENIVI Alliance actual scope and current projects.)
- Sensoris main purpose is to make sure that OEMs are not delivering different data, they should deliver the same data
- Prokop said it is out of scope of Sensoris to describe the system and software architecture, however they care about the "how" (e.g. protocols) to some extent
- Gerald: motivation for having a common data model in Sensoris is for instance the wipers model (e.g. 3 bits on the CAN bus)
- Gunnar: Gerald had a quite long discussion with Prokop about how OEMs provide the data, Sensoris does not care about the software architecture OEMs will use, more that the data that comes out is according to some shared standard (so that 3rd party developers can engage with more than one OEM).
- Gunnar: it seems they would reuse whatever architecture is defined by GENIVI
- Philippe: IMHO we should not fight for having an aligment of the data models, we could likely live with some duplicated representation for the data that overlap between Sensoris and VSS
- Benjamin: agreed
- discussion follows on GENVIVI scope vs Sensoris scope, VSS could be considered upstream w.r.t. Sensoris for the data defined in both projects
- another meeting will be scheduled in 4-week time, we need to do our gap analysis between Sensoris and VSS first
  - VCS-35 - Getting issue details... STATUS will be added to the new sprint
- Scrum review
  - VCS-42 - Getting issue details... STATUS done
  - VCS-47 - Getting issue details... STATUS done
  - VCS-31 - Getting issue details... STATUS kept in the backlog, can be activated whenever Don provides us with an update on the OCF Automotive group work
  - VCS-42 - Getting issue details... STATUS done,
  - VCS-52 - Getting issue details... STATUS created, we might be interested in knowing more about the OCF cloud services framework in the future when we start looking at the available technologies for the framework
  - VCS-40 - Getting issue details... STATUS done
  - VCS-50 - Getting issue details... STATUS done, Gerald provided an updated version of the CCS block-diagram highlighting GENIVI components rather than Autosar framework
  - VCS-33 - Getting issue details... STATUS done
  - VCS-35 - Getting issue details... STATUS added to the sprint, new Jira ticket created VCS-53 - Getting issue details... STATUS with blocking link added
  - VCS-38 - Getting issue details... STATUS updated
    - Gerald: IMHO ISO ExVe is not too exciting, performing a gap analysis between ExVe is to be further discussed with Kevin,
    - ticket is reassigned to Kevin to determine whether it is worth GENIVI buys the access to the specs from ANSI/ISO,
    - Gunnar: then we should likely check the architecture proposed by ISO ExVe can be filled by some components we have identified in the GENIVI communication framework
- Review of remaining items related to Analysis epic in the backlog
  - VCS-3 - Getting issue details... STATUS actually done with the various surveys completed
  - tickets to be added to the next Sprint starting on 10 September:
    - VCS-4 - Getting issue details... STATUS
    - VCS-5 - Getting issue details... STATUS
    - VCS-6 - Getting issue details... STATUS
    - VCS-7 - Getting issue details... STATUS
    - VCS-24 - Getting issue details... STATUS inputs for this work item will be given by the various gap analysis we have identified

Kevin Valdek opened the meeting and welcomed participants.
Discussing the organization of the gap analysis document...
Kevin has produced an outline proposal in CCS-48.
Gunnar has put some ideas into a wiki page
How do we slice the document. One chapter per compared (data model) covering all characteristics, or one chapter per characteristics/topic covering all data models.
- some discussion, no obvious conclusion - but let's write an outline for clearer proposal we can decide on.
SC: I would like to see a motivation chapter (for the GENIVI deliverable itself) to clarify document purpose and organization to the reader.
Gunnar: Seems like we need to rework this a bit with the given input.
Kevin: I volunteer to propose a (new, detailed) outline of the document
Kevin will rework the Wiki page that Gunnar started on (because it is now kind of obsolete).
Gerald: I can report on my action (CCS-28). Yes, overall we think CCC digital key is not much in scope. About car data, they are apparently not planning to create a data model / data taxonomy.
Gunnar: OK so their main deliverable is requirements, or a design and a programming API? If a programming API, there can be some similarity between an API and a data exchange model, so I would at least take some look (for overlap) if it is an API.
Gerald: ... yes it seems mostly requirements, use-cases, ... maybe more. I can check a bit more.
Kevin/Gunnar: We should include them (any organization that falls a bit out of scope) in the report nonetheless, just to document that we have analyzed them and drawn a conclusion.
Gunnar: Let's go through the JIRA tickets so we don't miss anything
Kevin: I can do that, I will display...
VCS 25 - Gerald: I sent a mail to Sensoris chairman about a joint meeting. No answer, need to retry this.
CCS-50 - (W3C workshop) Steve Crumb: Yes it is confirmed that GENIVI will present the project on the W3C workshop
CCS-2 This is Philippe's ticket and looks like a kind of overview tracking ticket (An Epic, sort of)
CCS-33 - (SENSORIS vs VSS) Still open only because the presentation has not been published in the Wiki (Benjamin was reminded)
CCS-25, Guru working on it. Keep it open.
CCS-34 - Sensoris vs CVIM. We think we can close the ticket. Overlaps other analysis.
CCS-38 - Steve Crumb: I have an update. I contacted ANSI via helpdesk. They require us a site license ($1200) to get the specification and we must put limits on the individuals that may read it. How many of you can get your own access via your organization?
Kevin: I can read the ExVe document.
Gerald and Guru: Also we can do that.
...BMW? (Benjamin can't go on audio, but we assume it ought to be accessible – follow up)
SC: GENIVI might purchase it only for staff since the limited circulation requirement will in that case not allow us to distribute to the members. Steve will investigate this.
CCS-39. Kuksa. Gerald will contact Sebastian to see status
CCS-42. Automat Security analysis. Gunnar: I will try to make sure it is presented to the security meeting this Thursday, as requested. We assume this ticket stays open until then.
CCS-47. Don: This is on track. I am talking to OCF tomorrow.
Kevin: Any other business?

- Kevin: yes, HM will contribute, quite open about the topic(s)
- Gunnar: yes, I will contribute
- Gunnar: when performing the gap analysis, we will identify new topics to investigate in addition to filling the content of the gap analysis
- Philippe: we are in an agile process, no worries
- Philippe: we need to get Daniel and Benjamin in the loop
- Philippe: I added Androif Auto P.Car to the list of projects we will review, the analysis of P.Car is starting in the Android Automotive SIG Vehicle Data APIs subproject, from this work, we expect to get a gap analysis between what AA provides and what the OEMs need w.r.t. the vehicle data APIs
- /TODO/ Kevin, Gerald, Gunnar initiate a thread offline to decide on the topics assignment, VCS-48 - Getting issue details... STATUS created and assigned
- Philippe: IMHO we need to start writing now
OCF update
- Philippe: welcomes Don Dulchinos representing OCF Automotive
- Don: introduces himself, Don is in consulting business - contracted to a security company which is interested in automotiven, tried the OCF Automotive project a year ago, set up an official liaison with GENIVI
- this year has done some work in April/May, OCF has started a cloud interface WG and wanted to set up a liaison with W3C and this took a long time
- in June there was an event in Colorado with JLR and W3C where they discuss to have a poc done, OCF has some interest in it but not strong enough
- then Don organized a call with with Ted and chair of OCF strategy,
  - OCF got recently renewed interest in this automotive group: Honeywell (smart thermostats), interested in the connection to the home
  - use case: someone is driving to his home and wants to get access to the home for setting thermostats
  - Gerald: is there the reverse direction use case ?
  - Don: not an Honeywell use case
  - OCF is interesting in having a demo at CES 2020, there is also an interop event scheduled before in December
- discussion on demos
  - Philippe: timeline for a Cloud & Connected Services project demo is for CES2021, we intend to work before on a gap analysis between various projects working on the vehicle data access and then we will scope and specify possibly a common framework for the vehicle data access and define APIs
  - Gunnar: back to OCF demo, what are the companies investigating the cloud APIs in OCF ?
  - Don: Samsung, Honeywell for instance
  - Gunnar: IMHO OCF would consider joining the GENIVI showcase ar CES 2019, you would need to contact the organiser of this event
- Don: I will talk to the governance of OCF (i.e. companies like Samsung, Intel, Honeywell active in the cloud interface)
- Don: is GENIVI active with the W3C ?
- Gunnar: yes, we are very much active, we have some kind of shared memberships, we work closely with them

Scrum review

1- Update on automat project

Philippe reports the outcome of the two calls he had with Automat project participants last week
- Renault participant on Wed 31 July
- Automat cybersecurity WP lead (from Trialog) on Tue 30 July (A,ntonio)
call wirh Renault
- VW had the biggest budget share in the automat project (up to 25%)
- the VW team involved was from the After Sales division (not from the R&D) and had a very short term vision of their needs
- VW interest was on what happened in the vehicle before a failure using histograms, because they wanted to minimize the telecom costs for data transmission and therefore the quantity of data transmitted
- there were actually two competing approaches for the vehicle data telemetry in the automat project: histograms for VW vs time series for Renault and Fiat (CRF Fiat R&D), the time series approach consisted in transmitting as many raw data as possible and processing them offline with big computers
- At the beginning of the project, HERE proposed to use the Sensoris approach for gathering vehicle data but there was nothing like histograms in Sensoris and this approach was not investigated further
- Renault did a proof-of-concept using a dongle to gather the data, VW and CRF decided to use existing ECUs (CRF used an existing TCU (communication box)
- At the end of the project the OEMs decided not to continue.
call with Trialog
- Trialog pointed to the following position paper from BDVA (Big Data Value Association), Antonio was one of the main contributors to this paper based on his work in the automat project with a particular focus on the privacy for big data
  - link: http://www.bdva.eu/sites/default/files/BDVA%20DataSharingSpace%20PositionPaper_April2019_V1.pdf
- Antonio mentions also the SAREF work on data ontologies pushed by EU whose motivation is to define and promote a European standard
  - link: https://www.etsi.org/newsroom/press-releases/1620-2019-06-etsi-releases-3-new-ontology-specifications-for-smart-cities-industry-4-0-and-smart-agriculture
- Antonio mentions W3C / Web of Things (WoT) work whose charter starts with a statement on the ecosystem fragmentation
  - link: https://www.w3.org/WoT/
- data privacy / security in automat
  - the interesting feature of the automat cybersecurity work is that it relies on existing standards (at the time of the project execution timeline)
  - Antonio said it would be good to review and restructure and update the automat cybersecurity framework according to recent US NIST work that takes into account the product lifecycle (to be shared witl the GENIVI security team)
Conclusion on automat
- Philippe's personal conclusion is that we have looked enough into Automat, unless we have an indication that Autosar will eventually use Automat CVIM as an input to their Cloud Services WG work, we in GENIVI should focus on Sensoris and VSS and ISO ExVe, we will also coordinate with Autosar on this
- call participants agree
- Guru: said he will look further into requirements for histograms as defined by automat and check what was not supported in Sensoris
- However the work done in automat on cybersecurity is good and relates to a big data architecture, Philippe recommends the GENIVI security team to review it and amend it w.r.t. US NIST work and extract possibly use cases to benchmark the MoRa tool
Additional information (for Kevin and others)
- yet another proposal from VW
  - look at Volkswagen Infotainment Web Interface (ViWi)
  - and at W3C automotive big data task force that explains how VSS and ViWI alignment are performed

2- Gap analysis deliverable: document owner and contributors, table of content update

Philippe: said he added P.Car (from AOSP) to the list of projects on Vehicle Data APIs we have to consider for the gap analysis
- P.Car is investigated in the AASIG Vehicle Data APIs subproject which started last week, look here
Kevin: asked whether we will have one or several deliverables on gap analysis
Philippe: said he is fine with both approaches, we need an executive summary to provide an overview of the results anyway, the format of the deliverables could possibly followed the one of the technical papers published earlier like GPRO white paper
Philippe: we need to assign sections / deliverables to contributors and nominate a document owner, we will create the relevant Jira iickets in the new sprint that will start next Monday
- Kevin: said he (and his team) can do a contribution
- Guru: will check with Gerald whether Bosch can do a contribution

3- Scrum review

VCS tracker https://at.projects.genivi.org/jira/browse/VCS
VCS-38 - Getting issue details... STATUS commented and updated, subtask created VCS-47 - Getting issue details... STATUS on how GENIVI could access ISO specs created and assigned to Steve
VCS-45 - Getting issue details... STATUS closing remarks on automat project added
VCS-46 - Getting issue details... STATUS table of content for gap analysis doc reviewed and agreed, closing remark added (see above), done
VCS-28 - Getting issue details... STATUS we need to find an owner for the review of CCC specs
we will close the sprint on next Monday 12 August

Gap analysis deliverable proposal

Kevin: the proposal from Philippe is good and we already have most of the necessary information about each project to start
Guru input:
- For the scope overlap/gap part we can bring in a table structure that we use for comparison
- We can define data characters from one project to another
- We can add information about how each project is being adopted by the industry
Steve: when talking about deliverables, can we draw experience from the work being done in the Android Automotive SIG? Data topics are being discussed there as well.
Philippe (added offline) : IMHO we could add P.Car as one of the inputs we need to review, to be discussed at the next meeting

Extended Vehicle ISO 20078 summary

Kevin presents - key points:
- The ISO standard was published end of Q1 this year. It covers concept and specific requirements for OEMs to follow when providing car data access to third parties via web services
- The standard consists of three different parts:
  - Content (resources)
  - Security framework
  - Access (consent flow)
- The standard does not enforce or recommend any specific car data protocols
- Should be useful for the CS project. To consider: if a deliverable should be compatible with the standard
- Documents are not available in the public domain, but licensed
Guru:
- There’s a lot of info in the document that is useful: Authorisation, REST API etc.
- As the documents are not in the public domain. Does GENIVI have any type of collaboration with the ISO body, to get access to the information? How could it be done?
Steve: will investigate if we can get a license

Presentation of Michael Ger and other participants.
Gunnar: I'm hoping Cloudera will provide great input to the "Big Data" flavor of the technical architecture (which likely complements the on-demand protocols like W3C VSI).
Gerald went through the minutes of the OADF meeting and through that described the different topics that are discussed in that forum.
Guru presented analysis of current Sensoris work (Analysis document *)
Benjamin presented AutoMat overview (slide deck *)

* please find links to material from the corresponding ticket in the JIRA project if not provided here.
Over time the material ought also be summarized as results of the project on the parent Wiki page.

Discussion:

Michael Ger asked for login. Gunnar answered via email.
Gunnar asked every presenter to update their corresponding JIRA ticket. If anyone is still having issues with login, email Gunnar and/or Philippe (on vacation this week).
Benjamin's presentation was a little short on time. Decided to follow up next week on more detailed discussion on comparing the data models.
Gunnar will create a ticket for "gap analysis" accordingly.

automat project security framework:
- Petar shows a comprehensive and informative slide deck detailing his findings during his review of the cybersecurity framework, look here
- Philippe asks how much the architecture of the vehicle data access related to the so-called vehicle neutral server (as described in the original ACEA paper)
- Petar: yes it is relevant, however there are many ways to establish the access
- Daniel (and his colleagues) will review the slide deck and provide feedback as well, Jira ticket created
- Gerald: istm automat project is quite open w.r.t. to the data they want to use, the security framework proposed there might be reused with different data sets
- Petar: the data set that goes with the automat project is the Common Vehicle Interaction Model (CVIM)
W3C
- Gunnar introduces the wiki page he prepared for describing the status of W3C work, he will present the status in the next call
Sensoris
- Gerald contacted his Bosch colleague who attended the Open Auto Drive Forum (OADF) two weeks ago, however his colleague is rather interested in HD maps and not so much by the vehicle sensor data which is Sensoris project focus
- For early July the public release of version 1.0.0 under the CC-BY-ND license is planned.
  - Public license: Copyright (c) 2017, 2019 SENSORIS Innovation Platform hosted by ERTICO - ITS Europe

- Also the Version 1.1.0 will be released for members only. This Version includes the specification of "Job Requests".
- added offline: Philippe spotted a one-year old presentation of the Sensoris project web site, link, reading this presentation is recommended, the presentation shown at the OADF event two weeks was much less informative
AOB
- schedule of weekly calls
- Philippe: we got a request to shift the call later in the afternoon in order to allow US participants to join. There seems to be possible participants from US Pacific timezone as well
  - quick poll: Daniel 4-5pm CET is the latest possible timeslot, Petar 4-5pm or 5-6pm CET is fine, Gerald 4-5pm or 5-6pm CET
  - this time is ok for US Central/Eastern but is anyway too early for US Pacific, we will likely end up with a second US Pacific friendly call

news
- project charter
  - Philippe is preparing a project charter for advertizing our work, we foresee to breakdown the project into 2 stages
  - Stage 1 focusing on data, i.e. what we are initiating now with an objective to decrease the fragmentation of the ecosystem with several different approaches to describe the vehicle data and the communication framework to access them
  - Stage 2 focusing on compute, initial though is to look into cloud computing platform to support mobility and vehicle autonomy
  - this charter will be shared with this project participants
- project tracker
  - Philippe: has created a Jira tracker https://at.projects.genivi.org/jira/browse/VCS
new participant
- Ilios introduced himself, he works for Obigo (Korea) and is their representative in Europe, he is based in Portugal-based representative attended the weekly call, he will be an observer for the time being, we had a discussion on the GENIVI Korea REG
- Gerald: asked Iliol whether there are public funded projects related to vehicle data in Korea
project status

we use the Jira tickets of the active sprint
Kevin (High-Mobility) has reviewed the automat project Commoin Vehicle Information Model and presented his findings CCS-26 - Survey AUTOMAT specifications (Common Vehicle Information Model - CVIM) In Progress
- the model describes big data for connected cars, it is quite different from VSS, it goes very deep in data harmonization and proposes several layers like signals + measurement layer + data package layer
- Gunnar: how is it compared to W3C
- Kevin: I have not seen the same information than in W3C
- Benjamin: we have a metadata Task Force in W3C, it is part of what next generation will do, we will have different kind of meta data, I would recommend to use the best practice, no competition now from W3C because there is no spec on this topic yet
- Kevin will summarize his findings in the wiki
Petar (Visteon) is reviewing the automat project security model CCS-32 - Read AUTOMAT security document In Progress
Gerald (Bosch) will spot the colleague within Bosch who attended the OADF conference, objective is to learn about the Sensoris specifications status CCS-25 - Survey SENSORIS specifications To Do

Webinar on W3C Auto WG & GENIVI collaboration, VSS and Vehicle Data definition future steps
Wednesday, June 12, 1300 CEST

recording

Monday 10 June - informal call

(This call was not intended/schedule and therefore had no official invite. Therefore only had 3 participants, but we still made progress in discussing the needed steps and plans which will benefit the group for next time)

Participants: Kevin, Petar, Gunnar

Using a Etherpad at Mozilla we captured:

Security guidelines

1. Collect and write down Security guidelines

Idea to produce general security guidelines for different parts of the data-oriented parchitecture.

E.g.
- For this API type you should apply this type of security...
- For this data link ....
- Web services and Mobile App requirements are different
- High Mobility has input to give here
- GENIVI Security group could review, if we have something written down
(We discussed to prepare a draft result first since the Sec Team does not benefit from an undefined "open question" at this point)

Data categories

2. Analyze What type of data is needed for different data users?
- Recognize that fine-grained filtering is needed, and mechanisms for it
but here we rather mean:
- Define names of groups of data, and describe them.

...Service classes that need different refresh rates
- Define groups and needs

Data contracts

- Quick intro to discussion in W3C before. It came up because it relates to the definition of the needs of each party. These needs eventually get formalized into contracts and that is the link.
- Grab-bag of tools/questions/terms to define business contracts or more technical contracts
- A kind of checklist...
- Purpose: Simplify business contracts on data, and make sure details are not lost

Tech constraints, technology choices

What are the Technical constraints that are imposed by the used technology?
- Communication paradigm and protocols (pub/sub, req/res, REST, MQTT)
- Middleware and components standing in the data path - caching layer, service layer, service bus

Surveying existing initiatives
- SENSORIS -> await this week's meeting and announcements, and see the outcome before defining actions
- Automat - Data formats and types and similar things are in their specs. Read and consider alignment.
https://automat-project.eu/content/open-cvim-specification
- W3C protocol content (being worked on with participation in group - but summarizing and presenting to the group is useful). Also Webinar tomorrow.
- CCC - have we confirmed there is nothing to reuse or relate to or is this still active? Reconfirm with PR and GS.
- ... follow up with the rest of the list

Question: SENSORIS - which companies can lead the investigation and alignment?
Answer:
- not Visteon - Petar did not reach anyone working with it
- not HM -
- Bosch? ... figure out this list

Terms/names/definitions
Steps:
- Review existing specs, do they include a Glossary
- ... and/or just start writing it down

Collecting Information in Wiki to complete the picture

- Action for all: Populate the Wiki with useful links
- Example of things to link to:
    Other Projects
    Specifications
    Presentations & Videos
    Implementations of basic technologies (open source projects)

Do this on the Connected Services home page: https://at.projects.genivi.org/wiki/x/PIAVAg

- AUTOMAT Security document looks useful to read in addition to CVIM spec.

Steps/Actions (current and future to be assigned)

- AI(all): First get projects.genivi.org Wiki account if you don't have it ~~(signup link is this one - it is part of JIRA~~) This is now changed and the old process should NOT be used: Please read the right column of the Wiki starting page for up to date instructions.
- Read AUTOMAT CVIM specification -- AI: Kevin -- read and summarize, present next week
- AUTOMAT Security document -- AI: Petar -- read and summarize, present next week
Future:
- Look at other AUTOMAT docs - are any other important to read?

Minutes

roundtable
- Rafael: xapix is a German company based in Berlin trying to create an api automotive platform www.xapix.io
takeaway from AMM
- Kevin: liked to talk about the standardization of car data, VSS, VSS 2
- high mobility has a different perspective, establishing the framework between high mobility, the car and the cloud
- a lot of different protocols, not only VSS 2 but also several others
- discussion on the various protocols
- Gunnar: at AMM we got a presentation by cloudera on the way data are managed in an automotive api framework (big data architecture)
- Discussion followed on capturing all the different players/users of the architecture. Third-party "app" development API, is that a programming API or "only" the W3C REST-based architecture?
High level vision on the project scope
- Gunnar: shows this slide deck
- Petar: agrees totally with slides 3&4
- one question on how to describe a behavior/service, need to represent different data types, and how to represent data that is made up of combining data from several sources.
- Gunnar: When it comes to combining signals into more refined data, the VSM project is investigating exactly that. It provides currently a python implementation. This can be useful to run on powerful IT systems, and/or be further refined to a optimized compiled code through code-generation for example.
- look at: GitHub/GENIVI/vehicle_signal_manager
- Kevin: I have a more organisational level, question, is VSS 2 more based on REST ?
- clarification brought by Gunnar on the various topics wip at W3C: VISS, VSS 2, etc.
- Clarifying VSS (Data Model @GENIVI GitHub), VISS v1 (W3C specification, which does also refer to VSS as the (minimum) data that shall be provided. VISS v2 (ongoing, in combination of augmenting VSS v2 to the needs). VISS v2 primarily focuses on adding HTTP/REST but some augmentations of the underlying features and data models happen in combination with this.
- Clarifying differences of work in data definition:
  - data-model description (Exemplified by VSS - shared among implementors)
  - actual data names and descriptions (Also exemplified by VSS - shared among data providers/users)
  - actual data names and descriptions (E.g. proprietary extended VSS additional, e.g. OEM private)
- Notice that VSS provides two different roles - defining HOW to define data, and also WHAT data, but these can be treated separately!
- There is some talk of "other data models" in W3C, not clear if this is just other proprietary data, described in VSS-like format, or if it is described in some other format. Also not clear what those other formats might be. VSS is generally adapted to match the needs that come up.
- The fact that some companies are worried to agree that all data names/descriptions are shared tend to block the discussion. We all understand that some data definitions are unique and private and VSS v1 already described private extensions. We understand that we benefit first from a shared way to describe it, and shared tooling, second that we also can benefit from some data being shared and defined (e.g. any "developer API" *requires* that to be defined at some point), and we also agree that companies may have some own unique and private data. Key point: No part should block progress on any other part.
- Kevin asked about if W3C VISS service covers security access control features. Gunnar answered that it is specified weakly on VISS v1 (but that still allows for implementors to add it), and that in v2 we will see what makes it into the formal specification (timing, progress), but there are some discussions.
homework
- review the draft workplan and Gunnar's slidedeck
- back to the project naming ==> homework for next week- coin other project names
AOB
- participation to OADF open conference next week in Munich ==> check whether some of your colleagues are attending it

Monday 27 May weekly call

Participants:

Petar (Visteon)
Gerald (Bosch)
Christian (BMW)
Benjamin (BMW)
Gunnar
Philippe

Minutes

roundtable
discussion on the project name, consensus on "connected services"
Slidedeck
- Gerald went again through the slide deck he presented at the AMM
Slide #3-4:
- Gunnar: needs to identify what are the higher level protocols we use on top of radio links
- discussion on the roles to play by various organizations for the definition of data containers, many organizations are currently competing on this
- Gerald: where is the most interested area for the genivi group ?
- Benjamin: I have multiple perspectives on those topics (slide 3), this is a highly fragmented ecosystem
- Petar: IoT style communications are more interesting to me, having a connected vehicle does not mean a vehicle is always connected in my opinion
slide 6 - ISO ExVehicle
- BMW: does not know who from BMW is involved
- /TODO/ each participant find who in their company is involved in ISO work ExVehicle
- /TODO/ Philippe contact Kevin to check whether high-mobility is implementing an alpha version of the ExVehicle concept and ask him to join the call
- Gunnar: does everyone has the same understanding of what a neutral server is ?
- Gunnar: as genivi we need to work on the interfaces between the various parts of the architecture
- Christian: agreed, we need to define the interfaces and *do it first*
slide 6 - Sensoris
- Gerald: they have something like a neutral server
- /TODO/ each participatant attend or get information on the OADF/Sensoris workshop scheduled in June
- The next OADF meeting will take place on June 12, 2019 in the Leonardo Royal Hotel in Munich, Germany. It will be combined with the first NDS Public Conference on the day after at the same location:
  - June 12: 12th Open Auto Drive Forum (OADF)
  - June 13: NDS Public Conference
  - link: https://nds-association.org/ (agenda is there)
slide 7
- discussion on how CCC and W3C sync on those topics
- Gunnar: in his opinion, this should not be not a constraint for our work
- /TODO/ each participant find who in their company is involved in CCC work
slide 8
- automat: it is likely a good idea to check this project because there are 2 OEMs involved (VW, Renault) and also there seems to be a comprehensive work on security and privacy
- Philippe: IoT - FYI genivi has a liaison agreement with OCF
- /TODO/ Petar look into OCF work
- Petar: kuksa project is quite comprehensive
- Autosar: cloud services - Benjamin discussed this with Sebastianat the AMM
- /TODO/ Philippe contact Sebastian (Bosch) about the Autosar cloud services
slide 11
- Gerald: thinks we need to pre-integrate some parts of the reference architecture
- /TODO/ Philippe ask Daniel (BMW) why he has a concern about abstract layers and invite him to join the call
Gunnar will prepare a slidedeck delivering his vision of what we should work on (in reference to the 5-level ladder shown in the panel on future vehicle electrical architectures at the AMM, look at slide #3 of future EE architectures)

Monday 20 May weekly call

Participants:

Petar (Visteon) new participant
Gerald (Bosch)
Guru (Bosch)
Gunnar
Philippe

Minutes

roundtable
- Petar: works with Visteon Connected Car team, he is a colleague of Giovanni (GPRO project), he is also based in Sofia, Bulgaria
- Petar is the solution architect of the team responsible for the overall architecture of the Visteon platform for connected services
- Petar has 12 year experience in connected services, for the entire stack from infrastructure to Web content end-to-end and for standard compliance
- Petar is currently more on R&D and prototyping than production
Slidedeck
- Gerald went through the slide deck he presented at the AMM
- Gerald: session went out very well, better than expected, a lot of experience people attended, Melco (Mitsubishi Electric) which is quite involved in W3C was there and showed a lot of interest

next steps following AMM workshop
- organization of weekly calls (instead of every other week): agreed
- /TODO/ Philippe send out an invite for the calls (starting next Monday) to the genivi-projects mailing list and the list of interested participants gathered at the AMM
- /TODO/ Philippe initiate a wiki page for the project
feedback from today's call participants
- Petar: workplan is quite interesting, told us he identified interesting work on IoT protocol standardization, the Homie protocol specification that he came across a couple of months ago. Although it is suggested to be home IoT-oriented, it is generic enough to provide structured data interface for IoT communication, which falls in the scope of Car to Cloud.
- link: https://homieiot.github.io/
- Petar: has a question on the authorization work, is it also on the cloud side ?
- Gerald: yes, you are right, something is needed on the cloud side
- Gerald: Daniel Wilms (BMW) expressed his concern about piling up abstraction layers
- Philippe: this has been a recurrent concern from BMW for a couple of years
- Gunnar: thinks this is a no brainer
