- DAPR - evaluation, discussion, plans for VSS integration
- Initial code drops from BMW. Full signal-source (SOME/IP) to GraphQL data server, serving VSS data.
Note: All parts of the end-to-end are not here yet, but these initial 3: - VSS serialization reusable C++ library? (not discussed today in particular - but note that serialization/messaging format remains a need for connecting to the frameworks such as DAPR and other transparent "transports" that do not define a format yet.)
...
- Several vacation/apologies this week from Bosch, BMW, ...
- Project updates above, for those that are available
- Catch up with Artem regarding AOS issues
- See above
- Also working on modularity - identifying components for reuse.
- VSC and tools
- → synergy opportunities with gRPC support in KUKSA.VAL?
- Let's discuss "decisions" taken during this development → how to find consistency with the VSC-related work (which intends to integrate gRPC and other technologies as needed).
- Awareness: CVII-TS: Binary encoding for VSS-based data transfer
- → synergy opportunities with gRPC impl. also here?
- Artem: We have seen some problems with binary encodings, so JSON mostly for now, which is adequate for a lot of the needs at the moment. We see potential need (for binary efficient encoding) however.
- Sebastian: For gRPC we replace some of the JSON protocol parts of course, but data encoding is often still using strings for simplicity at the moment.
- Gunnar: OK, I conclude this is still important and interesting to together define one or two canonical binary encodings for VSS.
- Updates/discussion on other priority-list projects:
- VISS v2 server Planning / Work Breakdown page
- Needs a proper "need"/request for resource allocation. Discussion on if current development frameworks (using python, NodeJS and other) are acceptable in in-vehicle embedded space or if this need actually does exist already.
- Android AAASIG update
...
- Introductions (Artem's first meeting)
- Brief discussion on AOS (principles, not the technology). Embedded parts are planned to be open-source. Process ongoing (outlook - a few months).
- Artem to give AOS architecture/tech overview next week
- Artem mentioned Android HAL using a VISS-protocol external server was implemented and shown by EPAM a few years ago.
- Gunnar: So this was before AASIG was started... It is good input, although current work has considered GraphQL as the protocol for the internal VSS-data server.
- => Artem to provide a link to the published code.
- New table-based tracking of wanted/expected/missing tech stack components was added to the CVII Tech Stack overview page
Feedback/changes welcome!- This could drive priority discussions also
- Sub-topics moved to separate pages for deeper analysis, e.g. protobuf (already existed), mqtt (new), etc.
- Eclipse: short discussion on the liaison with Eclipse, to be followed up with the Bosch team
