2022-10-12

Agenda:

1. Project summary
2. Autumn AMM meeting planning + longer term topic planning
3. ISO ExVe update

Minutes:

• WAII VISS based Vehicle to Cloud arch
  • Ulf has pushed the code he had summarised previously that introduces clients to provide a connection between VISS in the vehicle and the cloud.
  • See branch https://github.com/w3c/automotive-viss2/tree/ecuAdaptation for the code. The readme for the vehicle shows the arch
    https://github.com/w3c/automotive-viss2/tree/ecuAdaptation/client/client-1.0/VEC
• Florian continued his standards update from last week:
  • ISO ExVe cont.
    • Florian looped feedback to the ExVe group. The coordinator and Philippe agree that ExVe should be aligned and not creating new data model. Recognition that the two groups move at different speeds.
    • In answer to question whether standard can reference upstream the answer is yes. It would need to specify whether it is informative (info) or normative (must). So ExVe could reference a specific VSS version rather than duplicate.
    • ExVe WG continues to discuss whether its scope is pure data or interfaces as well.
  • Service Orientated Vehicle Diagnostics (SOVD)
    • Florian gave a quick intro to SOVD. This was unfortunately time limited. The group agreed we should ask Florian to expand on the topic after the AMM
    •  Florian's presentation:

Agenda:

1. Project summary
2. Autumn AMM meeting planning + longer term topic planning
3. ISO ExVe update

Minutes:

• Florian gave an update on ISO ExVe
  • Liason agreement concluded with Covesa
  • WG 6
    • REST (web) API for external access to car data
  • Discussion of  ExVe thoughts around data models and the challenges of firstly avoiding competing models and secondly the slow speed of ISO updates. If ISO adopts VSS as the model or aspects of it for example there is still a challenge around the version it uses and a probably faster moving VSS version upstream.
  • Discusssion of the use of VSS rule set outside of the VSS standard catalog, e.g. it would be useful for interoperatability, example would be development cost sharing and familarity, if non-VSS standard catalog data used the VSS rule set.

   1. Meeting next week

Minutes:

• Kuksa
  • Seb outlines background to the work in progress changes listed above
  • gRPC
    
    • Steve: You mentioned gRPC vs VISS. Where there use cases where you favoured one over the other that necessitated the new work on gRPC?
    • Seb: gRPC came about from feeders where gRPC more easily connected to lang like C++ then having to use websocket for VISS.
    • Steve: Ted reported last week that there were already multiple definitions for binary VSS data serialisation in protobuf. Is this adding another? Coordination needed?
    • Seb: Good point. Currently only single values are supported so there is no much (no data stream) to serialise.
  • kuksa dataserver:
    • gRPC get/set VSS data server. No WS
    • Currently parallel to kuksa VISS server.
    • Internal discussions ongoing in Bosch about respective uses for each and to what extent they may merge.
• AoB
  • Steve will be travelling after the Covesa Board Meeting at the time of next weeks call. Do you want to have a call next week or skip?
  • Paul B will host the call.

    • https://sdv.eclipse.org/sdv-contribution-day-june-2022/
  • Steve: repeat of Ford EV project proposal kickoff planned for Asia friendly timeframe
• Vehicle Edge To Cloud Edge (VE2CE) project proposal
  • Nick: It would be good if the proposal addressed the relationship to existing standards e.g. ExVe, SOVD so its clear avoidance of fragmentation is preferred.
    
    • Service Orientated Vehicle Diagnostics (SOVD)
      • They are working with AUTOSAR Concept 704
• Ted: EU interest in VSS https://ec.europa.eu/eusurvey/files/228a780b-d76e-4b63-bc3a-09a292d860ff/a9d67e78-cca0-4076-8d93-93a286654101

    • Detail is multi-faceted: transport / messaging / data pipes (possibly proprietary), data models
    • ISO currently does not specifiy data model but plans to look at what is available including VSS
    • Florian: ISO API currently most closely fits CIAPI
  • Ulf outlines how VDAPI can also be used as a App data API (see news slides in his proposal) as well as for data feeder
    • Steve: Are requirements for southbound interface to car network such as Some-IP/CAN/LIN quite different from an end user app, or to lesser extent in-vehicle "function app"?
  • Next steps
    • Paul: need to figure out how to bring this to a bigger audience to grow interest.

2022-06-08

Agenda:

1. Project Status

Minutes:

• VISS web client
  • Ulf outlines features:
    • GUI compared to mix of simple CLI tooling in WAII. Easier to use
    • Supports both "short" and "long term" authentication. Long term support requires changes in WAII

2022-06-01

Agenda:

1. Project Status

Minutes:

• Paul
  • Meeting upcoming to discuss proposal from Ford about collaboration on connecting EV Charging to VSS. Background is open smart use of charging data.
  • Next week he will be at Telematics Detroit. May not attend all meetings. Expect other members to be there also.
• Ted
  • Issac Agudo Ruiz (W3C VISS editor) has created VISS Client he will be open sourcing. He will present in W3C WG but it would be good to repeat in Covesa as well to get word out.
• Seb brings up question of ppl being spread out across multiple meetings
  • Ulf we could do coordination bi-weekly
  • Ted we could alternate: coordination one week, deep dive next week.

2022-05-25

Agenda:

1. Project Status

2022-05-18

Agenda:

1. Project Status
2. Next Deep Dive - CCS Component

Apologies:

• Sebastian

Minutes:

• NDN
  • Ted: Tier 1 experimenting. Interesting for its connection to VSS.
• VSSo
  • Ted: Observers welcome to join calls at any time. Observers need to avoid involving in voting or concept introduction. Contributions can also be made through github. Same applies to VISS calls.
• Paul: describing CVII and CVII Tech Stack to various companies. If ppl have input on how best to describe it then please say.
  • Florian: OEM presentation from Graham at AMM. Seen those slides repeated elsewhere since then. May be helpful in terms of where VSS is applicable.
• Next Deep Dive - CCS Component
  • Monday 23rd at 4pm CET.
• Christian: Does it make sense to present/introduce digital.auto (https://digitalauto.netlify.app/) here?
  • Paul, Steve: Yes. Should discuss about what you wish to achieve.
  • Christian: Need to tie technical work to biz connection.
  • Paul: (running out of time) Can take that offline.

2022-05-11

Agenda:

1. Project Status
2. Next Deep Dive - CCS Component

Minutes:

• CCS Components: State Storage Deep Dive Agenda
  • Timing
    • 15-20 min: Ulf Intro presentation on CSS Components: State Storage.
    • 40 min: reaction and building future plan
  • Technical API discussion
    • Design Issues in UIf's presentation
    • Review current State Storage component API
      
      • Anything to fix or extend?
      • In VSS Terminology State Storage is 'simple'. Is this component left (fit) for that use case and something else is needed for 'more powerful' or do we reuse/extend?
    • Abstraction APIs
      • To Feeder, to Server
      • Requirements
        • Speed
          • Low vs medium vs high frequency
          • Native for high frequency?
      • Kuksa.val is also a target
    • Last value vs time series
      • VISS protocol has some TS query
        • 'History filtering'
        • Simple support for this in current WAII. Other process (e.g. comms) must tell WAII to start/stop recordering. Then VISS client (e.g. cloud) must detect vehicle became disconnected and query for missing data.
        • Kuksa currently has no TS
  • Date
    • Monday 23rd May 4pm CET.

2022-05-04

Minutes:

• AMM feedback
  • Paul
    • Workshop
      • Input from Ricardo/NNG on interfacing VSS to ROS RTOS and its DDS messaging
        • Reached out waiting for reply to advance discussion
      • BMW (Adnan) input about links to big tech company
        
        • As above meeting needed to scope out
    • Next AMM
      • Need input on what ppl want to do to make workshops flow more organically
  • Sebastian
    • Workshops
      • Ppl came expecting 'readout' rather than workshop.
      • Positive was the good attendance and many newcomers, but the flipside of that was it was less 'workshopping'
  • Christian
    • Good discussions
    • Mixed expectations of new members/visitors vs call regulars
    • Good attendance in workshops despite them being scheduled at the end
    • It was cool
  • Florian
    • Good balance between panels, biz/tech track and workshops
  • Ted
    • Attended virtually
    • Enjoyed BMW presentation on VISS integration
• CVII Tech Stack Workshop talking points
  
  • SomeIP work occuring in Autosar. No schedule but something to follow.
  • BMW Android/VISS presentation. Major: VISS + Android VHAL feeder, Minor: GraphQL backend.
    • See deep dive discussion below
  • ROS / ADAS DDS to VSS
    • See Paul comment above
  • VSS Feeders / Data Store
    
    • Seb update on kuksa.val CAN
      • Loosely coupled, i.e. easily reusable
      • CAN feeder in python. Nice for prototype but for production likely look C++, Rust
      • CANOPI
      • Next step: wider discussion about reusing this work in eco-system. More eyes on the code etc.
    • VSS Feeder and Data Store abstraction
      • CCS Component status as starting point
        
        • Ulf's CCS component slides as possible starting point to deep dive
      • Need to discuss to what extent abstraction is possible or makes sense and for which use cases.
        • e.g. CCS Component current abstraction is simple single key/value API. Fine for low volume but would not scale.
        • In some cases might make sense to just use highest speed native API
    • Steve suggests start planning Deep Dive to discuss VSS Feeders and Data Stores
      • 1st might be:
        • 20-30 min Ulf present CCS slides, followed by wider discussion about abstraction.
      • Ulf sent apologies today. Steve will discuss with him either next week or slack
  • Deep dive next
    • Steve: What other things do you want to discuss in coming weeks?
    • Seb: Dig into what BMW needed/took from VISS protocol to understand their needs. Input may be useful towards VISS v3.
    • Ted has been having OSS roadmap discussion with BMW. Idea is to schedule meeting with Adnan about above when code available.
    • If meeting is in W3C slot then Ted will arrange 'visitor pass' for CVII members to attend.

1. Regular project recap
2. Meeting time for next two weeks before Europe switches to daylight saving
3. Develop the deep dive page: What (detail)? When (priority)?
4. AMM workshops

Related projects walk-through (every week):

• Minutes:

  • eco-system
    • Ted: Discussion planned with CCC (BMW representative) regarding coordination. They have traction around their digital key (keyless entry) and there are possible connections to VSC, VSS.
  • Eclipse Kanto
    • Thomas wants to go for next Monday 28th at the 'old CCS meeting' time for presentation.
    • Show of hands showed some ppl were available and Thomas wants to go ahead.
    • Rough plan for meeting is approximately 30 mins on Kanto from developers, followed by 30 mins on discussion. Focus is on the business of CVII Tech Stack and VSS eco-system, i.e. shared collaboration on non-differentiating technology.
  • VSS Data Storage
    • Discussion of attaching timeseries DB to CCS statestorage to provide "last value" backend for VISS.
    • Obvious first step. Does not preclude other processes from directly accessing timeseries data.
    • Wider discussion of how timeseries can be helpful, e.g. query and data processing, can follow on.
  • AMM
    • Discussion of CVII Tech Stack and issues around co-existing with parallel VSS track.
      • e.g. VSS has a VSS Layers discussion planned many will want to attend.
    • Deep dive
      • UIf reminds we should not neglect CSS/Northbound to Cloud. Although we need participation from ppl in that area.
    • CVII Tech Stack workshop
      • Seb: I am less interested in architecture discussion.
      • Ulf, Seb and Steve all express interest in discussion on feeders, data storage and data servers.
      • Working idea is for that to be the focus for a workshop. Possibly in afternoon to allow VSS workshop attendance.
      • More detailed discussion points need to be developed ahead of time.

    • Kanto
      • Tom reports that Maintainers can do a presentation from March 28th.
      • Discussion of content. Focus of deep dives is the scope of CVII Tech Stack, e.g. shared collab areas and understanding big architecture picture of how components fit together. Suggestion that 50% of time be presentation, 50% discussion of raised collab points.
• Deep dive scheduling
  • Doodle results
    • 5pm CET has good support but clashes with bi-weekly HV call. Paul would prefer to avoid rescheduling it.
    • 4pm CET (old CCS time) slightly worse in support terms. Sebastian may not be able to attend some but says group should go ahead. Ted thinks he can reschedule clashing meeting.
  • Conclusion:
    • Try 4pm CET.
• Deep dive topics
  • VSS / VSC integration
    • Seb: this overlaps with VSS and VSC groups and each has different participants. Needs coordination.
    • Steve: agree. I don't think "where" is important, i.e. not "owned" by Tech Stack, what is important is the topic.
    • Group participants are going to need to coordinate the topic. Upcoming AMM is going to be a good moment for everyone to be together.
    • Who is going to AMM?
      • Seb, Tom, Paul, Steve, Ulf, Florian (maybe), Nick (maybe), Erik, Philippe, Ted (would like to but obviously trans-atlantic)
  • General
    • Steve: please add your thoughts and topics to the deep dive page. Other the coming weeks we should refine and then prioritise to actually start the meetings.
• AMM
  • Steve: Is one hour enough?
  • Agreement that two hours would be better for workshop. Is that possible?
  • Paul will discuss with schedule planners.

2022-02-03

Agenda:

• Regular project recap
• Continue the extra meeting discussions. Work on the "deep dive" topic list.k
  • Fill out the timing doodle if you have not already.
  • Add to the deep dive page.
• AMM topic planning
• Tech discussion with remaining time.

Related projects walk-through (every week):

Apologies:

• Ulf

Minutes:

• Kanto
  • Thomas reports that project leads in Bosch working on Eclipse Kanto would like to present project
  • Source now available on Eclipse github
  • When?
    • Discussion about how to do 30+min session as this meeting has limited time
    • One approach is to do it as a "deep dive". Paul concerned about having people new to CVII having to sit through rest of the meeting.
    • AI: Thomas will get devs to add it as a topic to deep dive page and get feedback on when.
    • 5pm CET Monday is most liked time slot in Paul's deep dive doodle. Paul realises now that clashes with HV bi-weekly.
    • AI: Paul will consider timings.
  • What, why?
    • Assumption is that presentation is focused on CVII Tech Stack goals. Understanding architecture components and non-differentiating areas of collaboration.
    • From initial presentation discussion we can determine collab areas.
      • Some points that came up in first discussion:
        • Service definition
        • Container orchestration configuration
• Extra meeting / deep dive
  • Doodle results show preference for "old CCS time" of Monday 5pm CET.
  • Please update the "deep dive" topics page with your thoughts and ideas. This page will be used as driving force for organisation of coming meetings.
• AMM planning
  • Little time left to discuss. Please think about topic list.

Minutes:

• Project sync
  • CCS
    • Ulf summarises architecture. CCS State Storage as it is the component in WAII architecture that administrates the WAII VSS Data Store. Implementation allows a plugin approach to data backends. Once done will interface updated component into WAII.
    • Ulf happy to have seperate meeting to discuss details.
    • Sebastian mentions that dapr has a state-storage API to abstract DB backends State management overview | Dapr Docs
    • Work related to what steve is wanting to do with VSS Data Storage in vss-otaku.
    • Having three DBs should give good scope to discussions about VSS Data Stores and their interfacing.
  • Kanto
    • No updates since this project was first added. Should we keep it in the table?
    • Gunnar: We should list projects that have VSS functionality else we could list all dev tools.
    • Sebastian: No public source yet.
    • Proposal to remove it from table for now. We can add it back when needed. Any dissenters? None.
  • AWS
    • Gunnar reports that AWS mentioned they may have some VSS tooling to contribute
• Extra meeting / deep dive
  • Steve introduces CVII Tech Stack: "Deep-dive" topics page. Please add comments and topics.
  • Plenty of topics to get us started. Missing piece is when..
  • Open AI for Paul to post Doodle
• AMM (short of time)
  • Paul: We have CVII Tech Stack slots in the draft schedule. We need to decide if they are wanted and what the topics are.
  • AI: A wiki page will be created to work on the detailed Tech Stack talks

Related projects walkthrough (every week):

Minutes:

• Extra meeting discussion
  • Steve: I emailed a proposal to the list
    

    • After the extra meeting discussion last week I thought of one proposal on how to run them. In the Hypervisor group we would have what we called "deep dive" topics. A meeting dedicated to a single subject. We could do the same for the extra meeting. It would be on a set day and time to be agreed for continuity. However it will only go ahead if a topic has been agreed ahead of time, in the regular meeting. This avoids the trap of unproductive meetings and allows people to be selective about their interests.

  • Ulf: I like it.
  • Paul also supports the idea.
  • No other proposals made,
  • When?
    • AI: Paul will put up a doodle to identify some options of when ppl are available
    • Old CCS time should be one option: 4pm CET Monday
    • Time zones. More than one time slot may be needed. Doodle might gives us a couple of options from which we could select depending on topic participants.
  • Why?
    • Ulf: Integration of CCS scope including PoC for tech stack and CCS architecture diagrams.
    • Similar with Tech Stack work to date.
    • Anchoring discussions in shared architecture and terminology. Mapping prop
  • Naming
    • Weds: Tech Stack - eco-system/project coordination/sync
      • 1st half: recap
      • 2nd half: design work
    • New meeting: Tech Stack - detailed design
  • Topics backlog:
    • AI: Steve add page to add topic descriptions
    • (Alex) GraphQL implementation with VSS data feeders and storage. AI: Steve ask Alex to expand
    • Gunnar: Can translation is common request.
    • Gunnar: Refer CVII component list, e.g. protobuf, grpc.
    • Steve: Interfacing VSS Data Storage to VSS Data Servers
• Dev org
  • JIRA tickets
    • List things people can pick-up
    • In-progress collaborative development, e.g. VHAL project showing what tasks are planned, which in turn defines when work is done.

Apologies:

• Sebastian S (Bosch)

Minutes:

• Project coordination

• Android VHAL

  • Ted: W3C talking to Google Cloud ppl. They want to learn more about VSS to AOSP VHAL properties converter. Who to loop in to explain to them?

  • Paul: Loop me in.

  • Gunnar: Stefan from TietoEvry leading the work.
• VSC
  • Heads up on discussions in VSC call.
  • Followed by illustration from Gunnar on specifying protocol and access control for VSC APIs and mapping the latter to existing systems, e.g. in GraphQL and VISS.
• Extra meeting
  • Continue discussion of whether to repurpose the CCS meeting into a wider CVII Tech Stack meeting dedicated to deep diving design discussions. Do we do want to do it? If so when?
  • Ulf, Steve would like to see it continue. Alex is interested but is time constrained.
  • Two CVII Tech Stack meetings:
    • Weds: CVII Tech Stack: project coordination
      • This call. Coordination update as already done, followed by general discussion with time remaining.
    • TBD: CVII Tech Stack: detailed design
      • New call. Scope is deep dive on tech stack topics not specific to the VSS, VSC specific calls. Engineering focus. Will be small # of topics, known in advance.
    • AI: Create Doodle for timing
  • Deep dive topic list:
    • Alex: Discussion of connecting VSS Data Store to GraphQL
• Remaining 10 mins:

  • Southbound x2VSS conversion and code generators

    • Outline of two methods we currently have for conversion:
      • Android VHAL design pattern using JINJA template and yaml conversion description
      • vss-otaku is looking at a varient to the VHAL pattern that uses VSS vspec rule set to define the source data model. Outcomes will include pluses (vss-tools function set) and minuses (need to avoid polluting VSS standard catalog with source data types and units) of that approach.
    • We expect to need to expand the VSS Terminology set to include converters and generators. Please consider what they should be. A good set will ease coordination in and outside the group.
  • In-vehicle VSS Data Store

    
    

    • Steve outlined the direction of travel for VSS Data Store investigations in vss-otaku
    • Some universal themes to investigate collectively for Tech Stack such as connections between VSS Data Feeders, Data Stores and Data Servers.
    • Alex: I would really like to have a deep dive on the VSS Data Store and how it relates to what we are doing with GraphQL. To share our viewpoint and align.
    • Steve: Would love to. Your production/OEM perspective would be invaluable to guide later work connecting Data Stores to Data Servers.
    • Steve: This would also be a perfect topic for the proposed CVII Tech Stack Detailed Design meetings. Added it as a starting topic above.

Apologies

• Florian (DENSO)

Minutes

• VSS-tools,  A bit of additional progress in Android Automotive Vehicle Properties  (VHAL code-generation)  (Follow along in code_generation branch in vss-tools (and Manu's fork))
• Discuss possible automatic unit/scaling 
• Time-series database implementation, see CVII Tech Stack
  • Discussion with Stephen/Renesas about this point. 
• Stephen: There is a dataset that exists from previous demos.  (Values and timestamps) that could be used as data (after aligning it to VSS standards)
• Stephen (sharing screen): Many values look like Snapshots ( according to this definition), i.e. several signals measured the same time.
  
  • Gunnar:  Yeah, the snapshot format suggests to only store the timestamp once, if it is measured at the same time. 
  • Gunnar; Note "same time"/simultaneous might include a short time interval since the meaning of simultaneous is a bit sketchy in a discrete system.
• Tom: You can also reduce size of time stamps by transferring a delta-time compared to some reference.  
• Gunnar: Good point, worthy of adding a note to Data serialization / value formats page.
• Reminder: Register for AMM if you haven't.

AOS	Artem	-

Minutes

• Sebastian and Daniel W, Ulf, sent apologies
• Thomas working on AMM presentation
• eSync Alliance, upcoming
• OPIN, upcoming
• A bit of progress on AVRO encoding.
• (Repeated info), ongoing work on Android VSS-to-Android properties
  • The goal is to create something like this:  aasig-vhal-demo/tree/main/src repository ← this should already compile in AOSP (HAL implementation), but that example has a fixed set of signals.  Instead it shall be possible to code-generation from an arbitrary list of VSS signals
  • Here is a planning/background page named VSS to AOSP translation - WBS
  • The code generator implementation will be a kind of combination of VSS-tools (to read VSS) and vsc-tools (that shows how to use Jinja2 templates for generation).  The tools will need to consume also a "VSS layer" (deployment model) that describes how VSS signals are mapped to their respective Android counterparts. 
    Example of such mapping is on VSS to AOSP translation - WBS

Wednesday 2021-08-25

Project	Person reporting	Updates
ioTEA/Vehicle Edge	Thomas Spreckley	Node.js and python for containerized integration tests.  DAPR integration demo Bugfix Seat adjuster demo.  Developed, not pushed public though.
Kuksa.VAL	Sebastian	Merged first gRPC, no docs yet and don't ask... :) First logging feature impl.  Useful for debug/development.
VISS server implementation in Go	Ulf	Working on TLS implementation
VSS & Tools	Daniel Wilms  Gunnar    (Sebastian as backup)	For values that are defined in model (default, or min/max limits), shall "0" be valid if the signal datatype is float, or shall we require it to be "0.0"?  Discussion on  Structured datatypes support?   Major discussion opened, it is a fairly major change if included.  And of course discuss syntax in that case. Extensible (new) datatypes and units, no progress yet. vss-tools:  "vspec2yaml" proposal.  vspec is already yaml, but this expands all instances and flattens into a single output file, and includes uuid values.   Not yet accepted, maybe rename tool since vspec is basically yaml already.
VSSo	Daniel W  Ted	Rudimentary automated mapping VSSo<->DTDL
VSC & Tools	Gunnar	Fix needed to use python 3.8 (currently works only on 3.9) GitHub actions now run unit tests README updates to document gen() function changes
W3C VISS specification	Ted Ulf	Feedback on first public working draft: Minor bug - all messages to provide timestamp uniformly Bandwidth usage due to access token sent with every request.  Discussing if the token could be used like a session, for example by sending only the signature as a reference to a token that had already been authenticated.  Traditional session-cookie possibly going out of style in the future?
CCS-client repository	Ulf	-
AOS	Artem	-

Minutes/Agenda

• New participant: Francisco Uribe.  Quick roll-call/introduction.
• Project updates, see table.
• (VSS input)
  • Alexander: Is OBD branch really required?  Is it useful to model the data according to the channel where it is distributed.  (For example vehicle speed could be fetched on OBD, but also in other contexts)
  • Gunnar: Understood and it is a known issue, but this is not only about the channel of distribution but also of the signal definition.  Sometimes an existing defacto list of data already exists, and occasionally it might be useful to reproduce it without changing it so that people recognize the signals they are used to.  We are aware there are certain cases where this would lead to the same signal value being in more than one place, so it's a continuous discussion.  If the majority thinks the OBD branch should not be there, then it can be changed.  For every case, bring the discussion to the specific VSS call on Tuesdays.
• Update/plans on upcoming open source code for tools, from BMW:
• Alexander D (BMW):  We have for a while explored how to distribute VSS data in our platforms.  MQTT looked at before but we saw benefits with GraphQL.  Flexible queries!  GraphQL "invented" shortly after VISS v1?   Good community.  Implementations exist.   Possibility to tie signal sources in the system (SOME/IP services, REST services, CAN? ... etc.) to a single signal schema.  The schema is hierarchical, following VSS model (but possibly including more signals?)  Created python tools that generate the GraphQL schema from VSS.  There are some local extensions we have made (coming in second wave of tool release).
  • Mapping using a VSS-layer type (deployment model) which explains how to fetch the values from the system via an interface that is described using Franca IDL.
  • With this as input the tools generate code (e.g. resolvers for the GraphQL server)
  • Plan: Define a "ugly" Franca IDL interface and show examples of VSS-signal mappings on it.  The purpose is to include some "misuse" of Franca, or put another way, challenges in mapping VSS to "difficult" existing services.
  • First (partial) release of code fairly soon.
• Gunnar: First tests on serialization using AVRO.  See branch.  Will investigate python and C++ implementations first.
• Work started on VSS→Android property C++ binding code.  Just investigating VSS-generators and VSC/Jinja2 generation methods so far.
• AMM planning → CVII topics

Wednesday 2021-08-18

Project	Person reporting	Updates
ioTEA/Vehicle Edge	Thomas Spreckley
Kuksa.VAL	Sebastian	gRPC, Visual Studio dev containers for easier development
VISS server implementation in Go	Ulf	No updates.
VSS & Tools	Daniel Wilms  Gunnar    (Sebastian as backup)	Dropped travis file because GitHub actions cover all now Seat signals were sensors, now actuators VSS meeting group continues discussion of extensible datatypes and units (each separately).  At the moment it's basically a fixed list. - Which datatypes and units are predefined as part of the standard VSS model? - Are these also used in the current standard catalog?  Are there "standard" types that are not used at all? - Shall the model allow extension with new datatypes?  ... and/or with new units? - If it shall, what is the method of extension?  Shall the datatypes and units be defined in the program source code or read in from a configuration file. Progress is being made on these questions but all (many) stakeholders need to have time to weigh in. Early hints on upcoming issues:  Supporting struct data types (or not, as now), and possibly revisiting the definition of the enum type.
VSSo	Daniel W  Ted
VSC & Tools	Gunnar	vsc-tools: Generator function now uses type introspection on nodes, so there is no need to specify the node type in the template any longer. (Issue #16 ) vsc-tools: Unit test framework in place (pytest) with a first test example (#13) VSC/RPC meeting this week discussed way forward, and outreach to companies for one-on-one input regarding preferences gRPC, OpenAPI, and other standards are important to get into the mix, as well as Franca usage or migration path as described before. A new Franca input parser may need to be programmed from scratch, but this should be straight forward.
W3C VISS specification	Ted   Ulf
CCS-client repository	Ulf
AOS	Artem	Trying to find common ground around authorization etc.  Need a proposal for community to react. Service representation spec. also of interest (← VSC (and VSS) related discussion).

Minutes/Agenda

• Several vacation/apologies this week from Bosch, BMW, ...
• Project updates above, for those that are available
• Catch up with Artem regarding AOS issues
  • See above
  • Also working on modularity - identifying components for reuse.
• VSC and tools
  • → synergy opportunities with gRPC support in KUKSA.VAL?
  • Let's discuss "decisions" taken during this development → how to find consistency with the VSC-related work (which intends to integrate gRPC and other technologies as needed).
• Awareness:  CVII-TS: Binary encoding for VSS-based data transfer
  • → synergy opportunities with gRPC impl. also here?
  • Artem: We have seen some problems with binary encodings, so JSON mostly for now, which is adequate for a lot of the needs at the moment.  We see potential need (for binary efficient encoding) however.
  • Sebastian:  For gRPC we replace some of the JSON protocol parts of course, but data encoding is often still using strings for simplicity at the moment.
  • Gunnar: OK, I conclude this is still important and interesting to together define one or two canonical binary encodings for VSS.
• Updates/discussion on other priority-list projects:  
  • VISS v2 server Planning / Work Breakdown page
  • Needs a proper "need"/request for resource allocation.  Discussion on if current development frameworks (using python, NodeJS and other) are acceptable in in-vehicle embedded space or if this need actually does  exist already.
• Android AAASIG update
  • Plan to start implementing VSS to AOSP translation - WBS using a combination of VSS-tools examples for reading VSS and VSC-tools examples for code generation using jinja2.  Bittium is  leading.

Wednesday 2021-08-11

• No meeting this week.

• Starting conversations with/about AOS today
• CVII Workshop date set for 1 July (1600 CEST, 3h duration)

Minutes

• Introductions (Artem's first meeting)
• Brief discussion on AOS (principles, not the technology).  Embedded parts are planned to be open-source.  Process ongoing (outlook - a few months).
• Artem to give AOS architecture/tech overview next week
• Artem mentioned Android HAL using a VISS-protocol external server was implemented and shown by EPAM a few years ago.  
  • Gunnar:  So this was before AASIG was started...  It is good input, although current work has considered GraphQL as the protocol for the internal VSS-data server.
  • => Artem to provide a link to the published code.
• New table-based tracking of wanted/expected/missing tech stack components was added to the CVII Tech Stack overview page   Feedback/changes welcome!
  • This could drive priority discussions also
• Sub-topics moved to separate pages for deeper analysis, e.g. protobuf (already existed), mqtt (new), etc.
• Eclipse: short discussion on the liaison with Eclipse, to be followed up with the Bosch team

Updates on liaisons, alignment track, etc.

• Main topic right now is liaison with ISO group W6 for Extended Vehicle to discuss (potentially) introduction of data model definition in ExVe work.
• Plan for a small-scale meeting with some engineers involved in the activity.
• A deeper technical alignment work is required for SENSORiS.  It could be done by a volunteer or a small working group meeting  (doing the work, not talking about what could be done).

Project planning, other topics

• Upcoming - overlay architectures and plans from VehicleEdge, CCS, AOS, plus the VSS-tools, VSC-tools and various plans discussed in this meeting.  The purpose is to combine these into a view of the full tech stack.
• Gunnar reached out to EPAM for participation

Minutes

• Many vacations in Germany this week affects today's attendance.
• Gunnar: Some things might need to be repeated next week, but let's run a dress-rehearsal of the fixed agenda today.  Starting with updates.
• Sebastian: Note the upcoming Eclipse Conference.  There will be a presentation on KUKSA.VAL, but also other interesting things.
• Gunnar: (Tip from Stephen).  Note also this Embedded virtual conference starting June 3rd (several strong embedded Linux talks in the agenda).
• AOS, first look for related code:
  • aos-sdk
  • Yocto meta layer

Wednesday 2021-05-19

• Sebastian suggests every meeting should start with a project-update from each component development project, including IOT-event-analytics, and others. 
  • Start this next week.
• Gunnar notes that we should have clearer indication of who is attending/not every week.  Better structure and discipline for attendance, (and for agenda of course).  Time-boxing can be used if people only want to be on part of the meeting.
• Not much progress on VS* to AUTOSAR tooling this week.  Piotr had to leave meeting.
• Basic VSC generation framework now on GENIVI github → vsc-tools
• More VSS-to-bindings tools might come out open-source licensed, from another OEM's development
• A look at aoscloud.io - Renesas and EPAM.  Some open-source components.  Renesas has used VSS and VISSv1 in previous demos.  We are hopeful for setting up collaborative work on overlapping areas.
• Collecting up some more related SW project (some older, some newer):

  • https://github.com/aShinjiroUrata/vehicle-information-service-spec

  • https://github.com/aos-sdk/

Wednesday 2021-04-21

Agenda

• Development related to integrating with AUTOSAR
• "Plan B" on VSC tooling development - discuss options
• Bosch I-O-Tea and Vehicle Edge evaluation

Notes

• Integrations to AUTOSAR
  • Tieto platform running, ready to use for investigations
  • Gunnar:  For "Any"2Autosar tooling, first step is usually a definition of the mapping (spread-sheet showing language features that map to each other, where is it simple, where are challenges, etc.)
• VSS2ara would be basically solving the "autosar side" of the system, similar to how Franca → AUTOSAR XML converter was used with AUTOSAR.
• Alternative is to first focus on the "non-AUTOSAR" side of systems, e.g. generate a SOME/IP binding directly, or DDS, or other.  (VSS/VSC to SOME/IP binding directly).
• ASAM service oriented diagnostics seems interesting.

• "Plan B"
  • The VSC-related tooling is taking even longer time to go through company legal reviews and final approvals for releasing it with an open source license, although there is a clear desire to get it done.
  • A discussion started on how to develop a first set of tools in parallel with waiting for the other.

Wednesday 2021-04-14

Notes

• Tieto: AUTOSAR analysis ongoing.  Need tooling soon.  
• VSC tooling seems held up by something.  End of this week consider if we should launch plan B.  Talk to Magnus about it.
  
  VSC:
• Piotr: Has ASN.1 been considered as a definition language?  (it could be an alternative to protobuf?) 
  • ... the compilers are often able to generate a compact binary format
  • ... likely less availability of open-source tools.  There should be some however.
• Gunnar: For VSS I think it's "overkill" since VSS has very simple datatypes but for VSC and arbitrarily complex data definitions, maybe
• Gunnar: FYI: OpenAPI and AsyncAPI have however come up as potential reuse or inspiration for VSC definition.  Franca IDL is still a strong basis however.
  OpenAPI is only REST-focused and AsyncAPI seems to describe primarily a pub/sub direction.  
  
  VSS
• Stephen:  I was recently reading about GraphQL Federation that allows seperation of concerns and for domain teams to create parts of the data graph that are then federated into a whole. The seperation of concerns resonated with in-vehicle engineering where you have for example services with very different safety and security requirements. Could this help us?
  • Background reading:
    • video: Apollo GraphQL Federation introduction
    • Netflix uses it to scale their APIs and have some good blogs and a video on its use that have some nice practical illustrations:

      • blog: How Netflix Scales its API with GraphQL Federation (Part 1)

      • blog: How Netflix Scales its API with GraphQL Federation (Part 2)

      • blog: Beyond REST

      • video: How Netflix Scales Its API with GraphQL Federation
      • blog: Open Sourcing the Netflix Domain Graph Service Framework: GraphQL for Spring Boot (added after meeting)

           Cloud

• Iyyaz:  Regarding demo (AMM).  Docker-based stack and Terraform is being developed.

Wednesday 2021-04-07

Notes

• Reviewing and amending IoT-event-analytics and Vehicle-Edge projects page.  UML diagram overview.
  Dennis supporting.

• Tieto setting up internal meetings to figure out what to do next with the plans on AUTOSAR interoperability. 

        ... planning to build on VSC tooling
        ... Gunnar: Plan translation mapping and templates can start early

• Iyyaz has prepared some notes .  E.g. what is "the edge" by definition?

Wednesday 2021-03-31

Notes

• Review of wiki page IoT-event-analytics and Vehicle-Edge projects
• content of the wiki page is considered very useful by the participants

Wednesday 2021-03-24

• pipeline and configmanager come from IoT-event-analytics repository = Northbound
• kuksa val, hal interface+adapter, vss2iotea part of vehicle-edge = Southbound
• Dirk: There should be some useful UML diagrams.
• Christian to find the presentations/pictures that are useful here and attach to CVII Tech Stack page.
• Tieto still working on setting up AUTOSAR environment and planning.
• Discussed the need to coordinate development plans (e.g. bindings to DDS, SOME/IP, and-or code generators) to avoid overlap.
• Gunnar create a home page for Vehicle-Edge stack analysis and information.

Wednesday 2021-03-17

Notes

• Update on protobuf tool (merged)
• Bosch code released for IOT-event-analytics framework, and the vehicle-edge project to bring together all parts of the stack. 
• Discussion on AUTOSAR tooling
  • TietoEVRY to continue to seek out relevant people, bring into a design discussion meeting.
