• Meeting invite: Christian, Sri
• AMM wash-up
  • Goal: what went well, could be better, sessions/input we should be aware of
  • General including input from related sessions, e.g. Ulf's southbound session
  • Data Architecture workshop
    • Upload slides here COVESA All Member Meeting ~ October 10-12, 2023
• Central Data Service playground proposal
  • Goal: move towards project kick-off and work breakdown
  • Further input?
  • Agree next steps
    • Do we have general agreement/understanding on what we are doing regarding the service itself initially (the big picture What) and can move to getting the ball rolling on the details (e.g. checking docker status and choosing requirements of some use cases) of the how?
  • How to organise? e.g. Kanban, JIRA. Account for schedules and time zones by doing what we can online.
• AoB
  • Adnan: serialisation
    • Looking at msg serialisation between vehicle and car. Requirement to keep flexibility in terms of what is sent.
    • BMW will have a researcher looking into this. Can something be done in open? Payload only.
    • Looking for input.

Minutes:

• Serialisation
  • Adnan outlines (Adnan Bekan correct me if my summary is incorrect):
    • BMW will have a researcher looking into message serialisation between vehicle and car.
    • Scope is the payload only. Not the transport. However some flexibility in terms of what is sent in the payload is required.
    • Can something be done in the open in standardising this? Also looking for input on approaches.
    • Adnan notes the work done in the past during CVII Tech Stack days using AVRO with the esync alliance, but feels that is a heavyweight solution.
  • Various suggestions made about some possible approaches, such as encoding methods that take advantage of sparcity or lack of change.
  • Steve: the cloud connection has been cold for a while but only because its been waiting for someone to run with it. This should be of interest a wide group. I would recommend writing an outline or proposal of what problems you want to tackle down, along with some requirements. From that other inputs can be gathered along with people to work on it and a project formed. This should be of interest to the Commercial Vehicle group for example and their telematics requirements.
• AMM wash-up
  • Christian: various gateway solutions appearing, e.g. PennyBecker, HIM, Vehicle API etc. Implementations at different levels. Would be good to understand what they look to achieve as some are not directly comparable.
  • Arnaldo: difficulty for newcomers to get started. Wiki can be overcomplex to understand.
    • Data Arch landing page needs cleanup / simplification.
  • Neil: Agree. Some attendees talked to showed interest, but not everyone understands.
  • General agreement for the need for more guiding documents like HowTos.
  • Steve: I intend to remake the Data Arch landing page as discussed before the AMM to make it easier for newcomers.
  • Other sessions - Ulf southbound architecture session
    • Steve: Peter Winzell said in the W3C slack that he was working on a southbound feeder to WAII connected to Redis. Is it related to your work.
    • Ulf: Peter is using the WAII feeder framework I described in my session. His feeder connects to the RemotiveLabs simulator. As part of his work he's also updated the WAII DockerFile to use the latest code.
• Central Data Service playground proposal
  • Only 10 mins remained. Will be main topic next week.
  • Steve: Please consider what the near term next steps are, what use cases you want to explore and how we should organise the work

12th October 2023 - AMM Data Architecture Workshop

• (these are incomplete notes made after the event) 
• Workshop delivered as planned, except for compression of time on doc proposal:
  • Mongo DB/BMW (9-9:45)
  • 10-10:15 break
  • Central Data Service Playground (10:15 on)
    
    • Part 1: Readout of the proposal
    • Part 2: Workshop the base components and the possibilities for 'spins' using it
      • As well as the names below Piotr Krawczyk Neil Puthuff and Halim Ragab actively engaged in the discussion, along with Arnaldo's colleagues. Apologies if I missed anyone from the list - let me know.
        
        • Piotr suggested MQTT as event queue (see whiteboard picture)
        • Halim was interested in the project but wanted to know the boundary performance (latency etc) of the Service to be able to understand how it would fit in the overall performance of an end to end touchpoint. He took an action to provide input on what GM requires.
      • Outcome: Ford (Ulf Bjorkengren), BMW (Christian Muehlbauer), MongoDB (Arnaldo Vera Humza Akhtar) and Renesas (Stephen Lawrence ) all expressed interest in actively contributing. Enough interest to begin the project.
      • Whiteboard Images:

      • Group shot after the end of the session:
      • 
  • Documentation proposal discussion: 30 mins to be fitted in
    • As the Playground workshop was going well this was condensed with Steve simply showing some slides on the wider eco-system need for documentation on HowTo's etc.
