23rd November 2022

• Project status
  • VSS struct support heads up
  • VSSo meetings have restarted
  • Status of the collaboration between Covesa and Autosar and work on Autosar Gateway/Vehicle API
• Data Arch Themes
  • Given prior input on peoples interest Steve outlined an early roadmap for work that could create both PoCs and data patterns and which is easily adopted into related Covesa projects such as the Autosar Gateway and Android.
    
    • VSS Data Server
      • GraphQL (Covesa C++)
      • VISS Data Server
      • Aim: demonstrating two possibilities
    • VSS Data Store
      • Connection to Data Server
      • Embedded app DB (e.g. Realm), 'full' DB (e.g. IoTDB)
      • Aim: demonstrating two possibilities
    • Target: x86 (e.g container) => embedded h/w
  • Discussion:
    • Piotr: suggests adding VM to x86 targets as it allows investigation of concepts like VirtIO that may be harder in containers
    • Ulf: It makes sense to follow a pluggable architecture
    • Piotr makes the good point that the data architecture diagrams will need to evolve to cover higher function needs such as the proposed Vehicle API as well as the current coverage for data.
• AoB
  • Ulf presented his proposal for a thin API approach to the Vehicle API requirements for the Autosar collaboration.
    • This is not yet public. He will work on enabling that with goal to present it to the Autosar working group once it gets going.

16th November 2022

• Brief recap of Covesa project status
• Continuing discussion of future work
  • Paul: what would people like to see?
    • Felix: interested in GraphQL and connection of databases as data back-end. Along with what benefits data store may enable, e.g. processing at the edge.
    • Nick: ability for apps devs to discover what signals are available and on what terms, e.g. frequency.
  • Answered Felix's question about what work had gone on before.
  • Future is very much open to be set by the group. Cloud needs picking up again - with VSS/VISS now established the original work on CCS could move to other aspects. In-vehicle the component landscape is sketched but much work to be done selecting patterns based on data needs.
  • Steve showed a draft high level data arch diagram showing the proposed Autosar gateway communicating with QM data architecture.
  • Agreement that the interest around data architecture presented and discussed at the AMM is a useful starting point both for PoC investigation and likely creation of data patterns. Let's continue the discussions with a view to creating a strategy.
