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.

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.
