- Data Architecture Terminology.
- Steve did first pass review and made some edits.
- Got feedback from Felix.
- Intention is that along with the diagrams this becomes the basis for 'logical component' discussion in the Data Expert Group
- 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.

- 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 dictionaryDictionary.
- 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.
