Minutes
Kirill: Procuring a development board. Apparently graphics subsystem not starting on ARM64 (Google confirmed this...) Being investigated.
x86 emulation might be an option. More disk space coming soon to prepare for builds.
Alexander:
- New code now at https://github.com/COVESA/graphql-vss-server-libs
- Proxy instance should be a singleton. This is implemented.
- Standard logging and DLT logging is implemented.
- Custom scalers - translating values to the right format
- Query management
- Access control (permissions as defined in schema). JWT validation of each query.
- View README for more details.
- Actual server implementation probably available end of this week
- https://github.com/COVESA/vss2graphql_schema also extended functionality
Further discussions about challenges of mapping VSS/different environments.
The Franca mapping file is very flexible - can map to Franca attribute (including subscription of changes, or to just a broadcast
or to an explicit getter function exposed on SOME/IP. Similarly for writing, but it is defined independently => in theory different mappings for reading vs writing.
Stefan: At the moment interested in Vehicle-Properties translation primarily, but it is interesting to see this other concept progress.
...Good to see that Microsoft's C++ implemented GraphQL is mature enough. Apollo tried before which meant putting Java into the HAL layer, not ideal.
Compiling vspec2aaproperties code
Stefan: I tried also this but little progress (challenges with diferent computers, environment, disk space).

- Philippe Robin (COVESA)
- Gunnar (COVESA)
- Alexander Domin (BMW)
Minutes
- Updates on vspec2aaproperties code generator. Generated code through compilation with minor changes.
Need to add generation of getProperty... function for fetching dependent properties needed for complex calculation. This function is currently not included by reference to the implementation. - Manu: .... prefers generating these functions (variants depending on data type) according to if they are needed, which was done similarly with the type-conversion functions.
- Discussion about setting up a repeatable build environment. Apparently the standard way of building AOSP is "the whole system" (although rebuilding in the same directory structure is of course incremental and relatively fast). How is AOSP builds normally set up for CI systems??? There ought to be a structured way to reuse a cache of already built artifacts.
- Explanation from Alexander about the set of tooling (mentioned last week's minutes). A demonstration of the technology planned for the next CVII Tech Stack meeting instead, since it is also more widely applicable beyond Android.

Minutes
- Looking into the BMW code drops so far (Full end-to-end example of SOME/IP signal source to GraphQL server providing VSS data).
- https://github.com/COVESA/vss2graphql_schema/
- https://github.com/COVESA/test-someip-service/
- https://github.com/COVESA/test_franca2vss_mapping_layer
- These are 3 initial parts, actual GraphQL server + resolver code and more is coming.
- AA properties code generator:
- Manu: I would like to get feedback from the compilation tests before continuing.
- Need Stefan (TietoEvry)'s input, with more details, e.g. Android version tested on, and how to set up repeatable test environment.
- AASIG Dev Platform
- EPAM is willing to bring it up to date.
- Starting with Emulator as main target, and update to Android 12
- Then look at hardware BSPs later - most are likely still on 11, (but that's OK - use git branches or just different handling in the scripts to handle version diff).
- Is the AASIG components work not integrated?
- Manifest repositories exist, pointing to some AASIG created software components but they are not integrated yet.
...
Tuesday 3 August – 5:00 PM CEST
- Bittium and Tieto participants are back from vacation
- Stefan delivers a recap on the plan for the demo for the upcoming AMM
- then Stefan and Alex discuss the translation from vehicle properties from VSS
- eventually Philippe asks Bittium people to consider a possible contribution to the demo or the tests of the demo, to be discussed further in the upcoming calls
Tuesday 6 July – 5:00 PM CEST
- AMM dates are set for first week (4→8 October). Location, likely Germany and virtual hybrid.
- Tools. Alignment process ongoing (which creates some open PRs and issues in VSS and vss-tools before that)
Last week we established these next actions on the property translation work. Status updates below.
Feedback from VSS working group about general strategies for metadata (hierarchical?) Gunnar Andersson
- UPDATE: Question was raised (as a heads-up, future topic) last week's VSS. Will check for more feedback this evening but it probably needs a bit of time to get all stakeholders involved (it's a fundamental question).
Start work on code generator in vss-tools/contrib, output according to chapter "How to describe the complex translations" above.
- Question: Introduce templating language (JINJA2) in vss-tools? It is used in vsc-tools and could be useful also for VSS for more complex code generation than we have today.
- UPDATE: We still have no assigned programming resource to get this started
- Question: Introduce templating language (JINJA2) in vss-tools? It is used in vsc-tools and could be useful also for VSS for more complex code generation than we have today.
- Stefan awaiting approval to publish "hard-coded" example code.

Refocusing of project
- Philippe: IMHO we need to refocus the project activities, more OEMs are now working with Google, we need to recognize this and consolidate the knowledge the VHAL team has been building during the past year. I would recommend we revisit the work breakdown structure and the priority of activities
- Stefan: we should now analyze how to provide all vehicle properties through VHAL rather than through graphl, this means to look into the generation of bindings / the translation from VSS to vehicle properties
- review of the existing work breakdown structure (for the External Data Server concept)
- Stefan: I will check the architectural concepts we came up with in the past and propose another architecture to work on

Fosdem
- discussion on abstract, Stefan will work out an abstract and submit it by the end of the week DONE
- abstract text is the following
- title: Vehicle Signals access from IVI systems in generic way
- abstract:
- Accessing the Vehicle Network in a secure way is a challenge that each Automotive vendor and supplier must cope with. Rich collection of modern Operating Systems is approaching the industry and develop a need to have a standard approach to be reused across them. GENIVI Android Automotive Special Interest Group for Vehicle API is aiming is to provide a community voice and solution for generic challenges by example implementation. The presentation is a brief overview of the current progress of the common components that allows the vendors to move the effort needed for implementation to configuration of existing components.
- Agenda
- Android to utilize Vehicle Data Standard to access the Android Signals
- Current architecture
- Project setup (Environment setup references)
- Components overview (repositories, the purpose of each component)
- Access control and “external data server” for properties – outside Android
- Derived activities
- Apollo GraphQL as server – resolvers implementation
- Client implementation using Apollo GraphQL Java Client Library for Android
- VSS to Android properties translation
- Current challenges
- Way to describe the mapping between AOSP properties and VSS leaves – proposal and complexity of the solution
- C++ code generator to translate the properties
- Current challenges

- Stefan: we need to complete and finalize the demo platform for Q1, 2021
content of next version of the demo
- Stefan: we need to show the permission control promised by Alex, this is an important piece of code for the data server, it will allow us to validate the currently used EDS architecture, before digging into other architectures as suggested by Chris
- Gunnar: I agreed we need access control
- Gunnar: we will then have an opportunity to build other variants of the architecture and use a translation of VSS into vehicle properties, the initial work on translation can start now
- Philippe: suggests to have a working session on the translation next week (instead of having an all hands report which can be done with a slide deck distribution)
- all agree this is a good proposal
- Gunnar, Stefan and al. will prepare the working session via the mailing list

Security token validation
- Alex: some ideas on my desktop, although not formalized as a set of specifications yet
- the recording of Alex's pitch is here
- some hints on the discussion are given below
- in the web when using graphql, there is a user login name and password to connect to the data
- you need to authorize yourseld on the phone, the session is valid for a certain period of time, if you do things, the session will remain
- the server knows you
- before you can use a graphql application, you need to register, there is a link between the graphql server and your role
- let us switch in the car environment and let us deploy some kind of a server in the car
- what we learned from the web, graphql needs a name and a password
- the app which is installed in the vehicle environment shouf be identified and signed / qualified as coming from the BMW store or the OEM specific store
- the app should be made trusted in the environment
- Johan: I agree with the approach
- Alex: in the web we have roles & permissions stored in the server but not applicable to the vehicle environment
- more on the token: in the web, we have a token enhancement, after we logged on to the server and run through the authentication process, we got a token enhancement
- we can have the same in the vehicle environement
- (not captured...)
- access rights: each and every app should bring permission groups in the manifest file
- let us assume the app is allowed to access 20 atrributes
- let us assume the user driver needs to have more permissions that the user "baby"
- how do we handle this ?
- Johan: I understand the difference between the web and the car
- (not captured...)
- Alex: in the car we have an app where the user authorizes him once and then this app gives rights to all other apps that need it
- discussion continues on the sw architecture
- Gunnar: the key thing for me is that you can include the information that is to be exchanged in the token
- discussion on the token structure
- jira: AASIG-117 - Prepare use cases for the security token validation In Progress is in-progress

AMM debrief
- Johan: workshops were very good
- Stefan: Chris Simmonds who attended made a good contribution to the discussion
- Philippe: asks whether new work items were identified
- Stefan: the new items are listed at the end of the working session slide deck, there is an interest in digging into the Internal Data Server (IDS) architecture rather than the External Data Server (EDS) we have experimented up to now, with IDS the GraphQL would be exposed through the Android framework
- Stefan: have a couple of questions to ask to the working session participants, e.g. Ford and VW
- Philippe: will send a follow up email to Ford and VW to ask for their feedback on the working session
Backlog review - Work to do
- Gunnar: we need to finalize the building of the platform and the manifest
- Alex: what about the validation of the security token approach ?
- Gunnar: the GENIVI cybersecurity team can help reviewing the desing but will not implement anything
- TODO Alex prepare the use cases for the security token validation for next week (10 November), jira:

Stefan reports the status from last weeks to Johan with a highlight of new TODOs ready to be taken.
Piotr will continue his work on sqlite database between vssfeeder and graphql server.
All meeting members agreed, that the permission enforcement is something worth have on graphql side. Waiting for the status update from Alexander.

Participants
- Piotr, Stefan, Gunnar
- Alexander is on vacation this week
The completion of the in-vehicle is held up by access-control implementation in GraphQL server – awaiting status update from Alexander.
Gunnar has tried to unpack OpenDS sources from the Windows-executable via wine but it did not work. It requires "installing" Java (in the Windows environment) first, which did not work fully, and at least not so that the executable recognizes it as installed. Have to retry this on a Windows machine probably.
Stefan confirms again that once the "installation" completes, the source code will be on disk and can be extracted to be run in any other Java-capable environment (e.g. Linux).

- Sync up with Stefan. Will have more time next week for progress.
- Discussed how to compile OpenDS from scratch. The web site only provides version 5.0 only as a downloadable Windows executable! and no normal source code repository.
- Stefan: There is an eclipse project file, but no command-line build project like maven.
- Stefan explained how he compiled the Java sources manually.

- Reduced GraphQL schema to reflect supported values from OpenDS
- Authentication service that generates token containing granted permissions + App using GraphQL plugin to retrieve the values from server (Fuel properties usecase):
- TODOs from the code that can be taken:
- ExampleAppJava/src/main/java/org/genivi/vss/authenticationservice/MainActivity.java43: // TODO Move this connection boilerplate to VSS-SDK since this code will be shared across the clients
- ExampleAppJava/src/main/java/org/genivi/vss/authenticationservice/MainActivity.java69: .serverUrl("http://192.168.56.101:4000/") // TODO make it configurable
- ExampleAppJava/src/main/java/org/genivi/vss/authenticationservice/MainActivity.java84: // TODO Pass the token to the query
- ExampleAppJava/src/main/java/org/genivi/vss/authenticationservice/MainActivity.java88: // TODO Do sanity check of the response and its content
- service/src/main/java/org/genivi/vss/authenticationservice/IAuthenticationServiceImpl.java:41: // TODO decide when handle this exception
- service/src/main/java/org/genivi/vss/authenticationservice/IAuthenticationServiceImpl.java:44: // TODO Make the key shared between the server and client or change the algo to asymmetric
- service/src/main/java/org/genivi/vss/authenticationservice/IAuthenticationServiceImpl.java:61: // TODO Filter out the non-genivi-vss permissions
- vss-sdk-lib/src/main/java/org/genivi/vss/authenticationservice/VSS.java:12: // TODO Make it autogenerated from VSS
- vss-sdk-lib/src/main/java/org/genivi/vss/authenticationservice/VSS.java:17: // TODO Make Manager class to hide this intent there (similar approach to other services running in the framework) see TODO in client implementation
- Full setup has been recorded and is attached to this email and shows the following steps:
- Start of Apollo Graphql server with vss feeder, feeding the values from OpenDS
- Start Example application that is able to connect to Authentication Service and retrieve the token with permissions bundled
- Example application sends the query for retrieving Fuel data (capacity + current level).
- Indications that the values are the same as on server side
- JSON Web Token content
- Additionally, I have updated some of the Jira tickets. My actions (since 6 July) can be tracked via activity stream: https://at.projects.genivi.org/jira/secure/ViewProfile.jspa?name=Stefan.Wysocki

allocation of work
- Philippe: reminds the need to assign the work at application layer level in order to get a complete implementation "from top to bottom" and calls for volunteers
- Alex: brings in information about the development guidelines fo Android app using Apollo graphql
Alex: for application developpent there is a helper in Apollo to work with graphgl
graphql schemas are exposed via http
the connection between the graphql server and the app can be easily developed
the rest can be done in Android studio
Stefan: there is already a skeleton in the genivi github repo, explains how he added to the skeleton the "hooks" to authentication services and permission management
Stefan: will introduce one dummy permission for poc purpose and then based on that, the real properties will be created
Johan: my company has no resources available
Piotr: I can jump in and crzate the next iteration of the authentication skeleton
Stefan: will also be able to do some work
Alex: wht I acan offer is some code I have developed sometime ago, we could have a walktrough session to review the code
decision meeting with Stefan/Piotr/Alex/Johan scheduled on Thursday 18 June 9-11am CET
discussion on github repo organization between Stefan and Gunnar
TODO Stefan Wysocki to create a PR to move his own stuff from his private branch into the master branch
discussion on the data types to be exposed by the grapql server
Gunnar agrees with Alex proposal to have graphql expose types that are close to VSS types
if we do this, Alex will need to do something on the graphql server
discussion on type casting on 64-bit platform
Gunnar: we have obviously a type mapping problem, we need to express it more formailly
Alex: will start a short doc on type mapping between graphql and VSS in the wiki

- Stefan: we need to prioritarize the app development
- Stefan/Piotr are capable of developing the app but it would be good that other developers get involved
- Stefan: another next low hanging fruit is the VHAL implementation to retrieve the vehicle properties using a GraphQL query (see block-diagram), this can be done after implementing the data access in the app because it uses the same kind of query

sync with CCS project
- outcome of the sync meeting with Ulf from the CCS project
- Stephan: we could change the VSS database for SQLite and request for the properties on demand
- Gunnar: there are 3 cases that can be considered
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 ? These 3 ways of accesses are not considered as VSS leaves definition, but might be specified using VSS Layers. Then VSS feeder/Data Server (discussion on the role) can act accordingly (use cached or request for fresh value).
- TODO Gunnar to write prepare a block diagram describing the various cases
- Alex :agrees with the 3 cases
- Alex: do we really need a database which might be seen as an overkill for me ? some hash-map in memory might be enough
- Alex: when the data are not changed at all, what do we do ?
- Gunnar: do we need a database ? no, but there is an implementation that exists
- Alex: are the feeder and the grapql in the same process ?
- Gunnar: I think there are separate processes and we need IPC soemwhere unless we put everything in one process
- Stefan: but even if we use one processor we need some thread sync.
- Piotr: IMHO using hashmap and sync implementation would result in the same complerxity than using SQLite
- Gunnar agreed
- Gunnar: debouncing ?
- Gunnar: there might be some higher performance database, but basically we need only a key value store
VSS to Franca
- VSS to Franca tool was updated by Gunnar to implement the someip connection

backlog review
- Stefan - Alex: plan to implement the permissions model, next step is using the same data with graphql with the permissions model added
- question: do we reuse what BMW is using or do we implement something in parallel ?
- reusing the database from CCS to be more solid
- Gunnar: it depends on what we want to store, depends on the use cases, simple key-value pair storing might be enough
- Gunnar: for next milestone we will keep the values in memory
- Gunnar: we do not need a very advanced data base
- Philippe: how to identify a useful use case ?
- Stefan: restrict the driver from accessing a given speed limit, zooming some control , average data, minimum & maximum value
- Gunnar: displays the current values and some client side statistics, no need for a database

- demo can be shown as first milestone, i.e. at the virtual tech summit workshop
- Stefan will contact gunnar after
- Stefan: shows the set up of this demo and explains the problem he has with the nxtworking between the VM and the simulator that runs on windows
- Philippe: why don't you the GVS (GENIVI Vehicle Simulator) that runs on linux ?
- Stefan: we should use at a later stage a "better" database like SQL for instance
- Gunnar: can you all take into account the packaging, like we did in other projects where we use a docker setup ?
- Alex: I am fine with the docker packaging
- Gunnar: next step would be to integrate this into a dev kit and running an app on Android
virtual technical meeting - workshop preparation
- Alex: I had a call with Stefan yesterday, I do not know how deep we need to address the topics, let us do a brief overwiew of the topics
- topic #1 - VHAL implementation based on the graphQL implementation
- Google requires OEMs to implement properties in the Google way
- we want to deliver these properties outside the graphql server
- I hope to have JLR working on the proof-of-concept implementation with us, then we need to identify which workpackages need to be implemented
- Philippe: JLR people are shutdown for the month of May and will not show up again until next month, it is a good idea to prepare an updated work breakdown structure
- topic #2 - permission group
- Alex: this is about the concept introduced by Gunnar about the VSS layer concept; I would like to have a discussion on which concept we will follow in the future
- Alex: in our architecture we have different players, player 1 is the app, player 2 is the authentication service that generates the token, player 3 is the dataserver
- Alex: I intend to present my understanding of what I have learned about permission management
- topic #3 - graphql schema
- Alex: I generated the graphql scheima for the GENIVI VSS standard tree (on github)
- there is a private area for each and every OEM has his own branch
- do we need an additional layer to be integrated into the graphql schema ? or do we create empty leaves in our schema ?
- Gunnar: we need both actually
- Alex: do we talk about the generation process at the workshop ?
- Gunnar: I would like to invite you, Alex to partiicpate to W3C call on VSS call this evening

- BMW has only the EDS implementation, not the Internal Data Server one
- Alex: the permissions are not yet what we need
- discussion on the work to do for the authentication and the access control groups
- Gunnar: we need to do a more formal description of things to be done for the authentication
- Alex: might be able to do some work in the next days, will try out my ideas on an actual implementation, as soon as I have something (next week possibly), I will generate some docs like ppt
- Alex: tooling is not clear for me yet, as soon as we agree on the way to specify things, we will talk about tooling and manifest generation
- discussion on the naming of artefacts
- Alex: we want to have a nodeJS graphql implementation running
- Alex: I can describe the nodeJS and graphql installation and the deployment of json files
- Gunnar: the wiki page for documenting tihs is AASIG: Implementation notes
- /TODO/ Alex to describe the nodeJS and graphql installation in the above wiki page
- Stefan: at Alex, since you have the authentication implementation under way, could you spent some time to describe what you have done so that we can identify the leftovers ?
- Alex: I can explain that, for instance we need a json web token implementation
- /TODO/ Alex & Stefan to clarify what could be the contribution of BMW & Tieto to the authentication mechanism implementation
