Cross Group ArtifactsOn topics, personally I would to advance discussions on the cross group artifacts. Things like data sets, schemas, VSS packaging, meta-data, governance and touchpoints. We know the data modelling discussion is being re-energised.There is also a proliferating set of projects. What synergies are there across them? What are the re-use and collaboration opportunities to do more with less?This should all be pragmatic, with a view towards outcomes.

2024-02-29

  • Central Data Service Playground now very close to minimum viable product
    • Operational: As we spin up things like online documentation makes sense to both leverage existing experience with say VSS and to do it in a consistent way with what exists to ease overall maintenance, e.g. similar operational patterns.
      • Any existing artifacts we can leverage?
      • Tips, e.g. CI?
    • Review: Will be increasingly asking people to try, review and give feedback.
    • Wider eco-system: Will be considering examples and connection of "lego" to other parts of Covesa eco-system.
    • https://github.com/COVESA/cdsp
  • Discuss Covesa approach to images in Docker Hub
    • Need to understand what is required to upstream and maintain images of Covesa tech in Docker Hub
    • Any group experience we can leverage?
  • Something related to VISS project transfer from W3C?
  • Bosch open source pages mentions VSS - https://opensource.bosch.com/
  • ChargeX
  • How to "refactor" meetings
    • Not many subject or participants lately
    • Change to bi-weekly or on need basis (cancel if no agenda)?
    • Paul: Board wants to see the big picture, that is the topic of this meeting
    • Erik: Please propose topics for future DEG meetings
    • Erik: Possibly revive the backlog at https://github.com/orgs/COVESA/projects/1
  • AMM
    • DEG Update -message, discussion topics,
    • Proposal from Carina

Meeting notes

2024-02-15

  • VISS governance
    • If we want to handle VISS as a "standard", do we need a stricter process for merging changes and releasing new versions (compared to for example VSS)? Like formal review period, formal vote in TST?
  • AMM Agenda
  • AMM Agenda - proposal from Carin
    • With regards to planning for AMM agenda there was one idea / wish I had on the agenda that I'd like to run by the three of you... Many of the VSS sessions at AMMs are (and should be!) related to quite nitty gritty development by the working group. However; at  the session I've been I've heard the repeated frustration from developers, mostly at OEMs, for how to match signals from proprietary ones to VSS in an efficient way. I've brought up the idea with our developers that it would be interesting with a brainstorming session at AMM Gothenburg or co-problem ideation for generating different potential solution paths for how to work efficiently /methodology / tooling /AI tests etc. The feedback from RemotiveLabs engineers was "we'd like to participate in such a sessions (we have ideas and even tickets for this internally ), but currently we are not equipped /prepared to lead such a session". For your information, we are planning to join the meeting in Gothenburg with 4-5 people (2-3 of which engineers i.e. you don't have to put up with only me and Emil this time hahah )...  so I guess what I'm trying to do is propose to you guys if you like the idea that COVESA VSS chairs sets up a slot for this? (i.e. RemotiveLabs not involved more than anyone else who joins). Then anyone can take 5 minutes to explain an idea / proposals but to be a session where experiences and ideas are shared to connect further. Does this make sense? I think it would complement the other types of VSS sessions.

  • Catena-X - shall we approach them? Do we want to collaborate, and if so how.
