• Diagrams
  • Christian: We should show that the data server/state storage combination in-vehicle can be reused in the cloud and mobile device as well, i.e. data centric architecture reuse of arch.
• PoC
  • Christian: Is this intended to be public?
  • Steve: Yes
  • Illustrations to show possibilities:
    • Covesa github all public
    • x86 docker
      • Major components of the basic 'lego':
        • VISS data server, e.g. WAII
        • State Storage, e.g. add Realm, Apache IoTDB
      • Step 1: DBs via WAII (CCS) State Storage component
      • Step M..N trials using the basic lego to prove/investigate various topics:
        • High frequency
        • Knowledge pyramid, AI at the edge
        • Multiple data models
    • Automotive H/W
      • Generic code could be implemented on Automative H/W for some appropriate topics, e.g Latency Southbound
    • Feedback:
    • Piotr: Could have a PoC variant that shows support for different OSs via vsock for example to show possibility of southbound data from various sources in the car.

3rd May 2023

• Welcome to Arnaldo Vera from MongoDB. Short overview of the work of the Data Architecture pillar.
• People report successful AMM
• Combining VSS with other data models
  • Logistically neither Ulf or Christian get to each others presentations on this subject
  • Positive discussion to look at the proposals and find commonalities for way forward
• Logical Components / Terminology
  • Discussion of the usefulness of logical component diagrams as found in the CVII Tech Stack/CCS diagrams and the Terminology dictionary.
  • Avoids the competitive aspects of talking about products, falling into specific system architectures and gives a common approach for discussion.
  • Useful for design patterns, deployment scenarios and architecture documents.
  • How to move towards a common view?
    • Review terminology list.
    • Christian will see how the components fit the i7 showcase demo.
    • Collectively iterate both the terminology and diagrams.
• Data Server / State Storage PoC basic building block
  • Steve summarised the discussion Thursday at the AMM to create a basic building block PoC consisting of a Data Server and State Storage.
  • The aim is a reusable component that could be configured to extend it for use in various deployment scenarios, e.g. connecting Vehicle API gateway.
  • At the same time the basic block could also be used to investigate connections between server and storage, e.g. low latency data.
