Minutes:

• AMM feedback
  • Paul
    • Workshop
      • ROS/DDS to/from VSS,  input from Ricardo/NNG
        • Reached out waiting for reply to advance discussion
      • BMW / Adnan input about big tech company links
        • Meeting needed to scope out
    • Next time
      • Need input on what ppl want to do
  • Sebastian
    • Workshops
      • Ppl coming to expect 'readout' rather than workshop
      • Positive: good attendance
      • Flip is less 'workshopping'
  • Christian
    • Good discussions
    • Mixed expectations of new members/visitors vs old stagers
    • Good attendance of workshops despite at being the end
    • It was cool
  • Florian
    • Good balance between panels, biz/tech track and workshops
  • Ted
    • Attended virtually
    • Enjoyed BMW presentation on VISS integration
• Workshop
  • SomeIP / Autosar
  • BMW, Major: VISS + Android VHAL feeder, Minor: GraphQL backend.
  • ROS / ADAS DDS to VSS
  • VSS Feeders
    • Seb: kuksa.val CAN
      • Loosely coupled, i.e. easily reusable
      • CAN feeder in python. Nice for prototype but for production likely look C++, Rust
      • CANOPI
    • Abstraction
      • CCS Component
  • Deep dive next
    • Seb: Dig into what BMW needed/took from VISS protocol to understand their needs. Input towards to VISS v3.
    • Ted will maintain OSS roadmap discussion. Schedule meeting with Adnan about above when code available.

Agenda:

1. Project Status
2. AMM Sessions

Minutes:

• AMM workshop Thursday afternoon: 2-3 hours (Updated working list from last week) 
  
  • Discussion of what the group wants to work on and discuss in near-term
  • Currently the sessions are split into the two related topics VSS Data Storage, including feeders and VSS Data Servers
  • Topic brainstorming:
    • VSS Data Storage (including VSS Data Feeders) (Southbound)
      • Data Storage implementations:
        • DBs: redis, timeseries etc
      • Architecture: Single central vs distributed vs direct sensor connect (bypass store)
      • Feeders: CAN (kuksa.val have closed some gaps), some/ip,
      • Timeseries vs last/single value
      • Interfacing into data servers
    • VSS Data Servers (Northbound)
      • VISS v3? (Duplicate: Will be brought up in prior VISS session so likely handled there)
      • Are VISS backend abstractions possible: storage, feeders?
      • GraphQL - in-vehicle?
        • BMW VISS→Android abstraction/interface/data server
      • VSS Data Servers to cloud
      • Data processing
        • Ted explains they see issues with OEM cloud data. Time slice not short enough for some forms of h/w maintenance wear tracking so have to do their own. Possible need for some in-vehicle processing. Also issues with in-vehicle caching with insufficent IO.
          
          • In-vehicle vs cloud
          • In-memory vs storage
