Tuesday December 7 – 5:00 PM CET
Participants
- Kyrylo Skidanov (EPAM)
- Stephen (Renesas)
- Stefan Wysocki
- Gunnar (COVESA)
- Alexander Domin
Minutes
Kirill: Procuring a development board. Apparently graphics subsystem not starting on ARM64 (Google confirmed this...) Being investigated.
x86 emulation might be an option. More disk space coming soon to prepare for builds.
Alexander:
- New code now at https://github.com/COVESA/graphql-vss-server-libs
- Proxy instance should be a singleton. This is implemented.
- Standard logging and DLT logging is implemented.
- Custom scalers - translating values to the right format
- Query management
- Access control (permissions as defined in schema). JWT validation of each query.
- View README for more details.
- Actual server implementation probably available end of this week
- https://github.com/COVESA/vss2graphql_schema also extended functionality
Further discussions about challenges of mapping VSS/different environments.
The Franca mapping file is very flexible - can map to Franca attribute (including subscription of changes, or to just a broadcast
or to an explicit getter function exposed on SOME/IP. Similarly for writing, but it is defined independently => in theory different mappings for reading vs writing.
Stefan: At the moment interested in Vehicle-Properties translation primarily, but it is interesting to see this other concept progress.
...Good to see that Microsoft's C++ implemented GraphQL is mature enough. Apollo tried before which meant putting Java into the HAL layer, not ideal.
Compiling vspec2aaproperties code
Stefan: I tried also this but little progress (challenges with diferent computers, environment, disk space).

Participants
- Kyrylo Skidanov (EPAM)
- Johan (Melco)
- Stephen (Renesas)
- Manu (Bittium)
- Philippe Robin (COVESA)
- Gunnar (COVESA)
- Alexander Domin (BMW)
Minutes
- Updates on vspec2aaproperties code generator. Generated code through compilation with minor changes.
Need to add generation of getProperty... function for fetching dependent properties needed for complex calculation. This function is currently not included by reference to the implementation. - Manu: .... prefers generating these functions (variants depending on data type) according to if they are needed, which was done similarly with the type-conversion functions.
- Discussion about setting up a repeatable build environment. Apparently the standard way of building AOSP is "the whole system" (although rebuilding in the same directory structure is of course incremental and relatively fast). How is AOSP builds normally set up for CI systems??? There ought to be a structured way to reuse a cache of already built artifacts.
- Explanation from Alexander about the set of tooling (mentioned last week's minutes). A demonstration of the technology planned for the next CVII Tech Stack meeting instead, since it is also more widely applicable beyond Android.

- Alexander Domin (BMW)
Minutes
- Looking into the BMW code drops so far (Full end-to-end example of SOME/IP signal source to GraphQL server providing VSS data).
- https://github.com/COVESA/vss2graphql_schema/
- https://github.com/COVESA/test-someip-service/
- https://github.com/COVESA/test_franca2vss_mapping_layer
- These are 3 initial parts, actual GraphQL server + resolver code and more is coming.
- AA properties code generator:
- Manu: I would like to get feedback from the compilation tests before continuing.
- Need Stefan (TietoEvry)'s input, with more details, e.g. Android version tested on, and how to set up repeatable test environment.
- AASIG Dev Platform
- EPAM is willing to bring it up to date.
- Starting with Emulator as main target, and update to Android 12
- Then look at hardware BSPs later - most are likely still on 11, (but that's OK - use git branches or just different handling in the scripts to handle version diff).
- Is the AASIG components work not integrated?
- Manifest repositories exist, pointing to some AASIG created software components but they are not integrated yet.
...
Tuesday 3 August – 5:00 PM CEST
- Bittium and Tieto participants are back from vacation
- Stefan delivers a recap on the plan for the demo for the upcoming AMM
- then Stefan and Alex discuss the translation from vehicle properties from VSS
- eventually Philippe asks Bittium people to consider a possible contribution to the demo or the tests of the demo, to be discussed further in the upcoming calls
Tuesday 6 July – 5:00 PM CEST
- AMM dates are set for first week (4→8 October). Location, likely Germany and virtual hybrid.
- Tools. Alignment process ongoing (which creates some open PRs and issues in VSS and vss-tools before that)
Last week we established these next actions on the property translation work. Status updates below.
Feedback from VSS working group about general strategies for metadata (hierarchical?) Gunnar Andersson
- UPDATE: Question was raised (as a heads-up, future topic) last week's VSS. Will check for more feedback this evening but it probably needs a bit of time to get all stakeholders involved (it's a fundamental question).
Start work on code generator in vss-tools/contrib, output according to chapter "How to describe the complex translations" above.
- Question: Introduce templating language (JINJA2) in vss-tools? It is used in vsc-tools and could be useful also for VSS for more complex code generation than we have today.
- UPDATE: We still have no assigned programming resource to get this started
- Question: Introduce templating language (JINJA2) in vss-tools? It is used in vsc-tools and could be useful also for VSS for more complex code generation than we have today.
- Stefan awaiting approval to publish "hard-coded" example code.
- UPDATE: Approvals slow because of vacations. Won't happen before Stefan's vacation. (A few actions for Stefan to do, testing etc.)

"Development platform"
Manu's feedback
- Manu: Dockerfile in master uses Ubuntu 14.04 which is very old
- Gunnar: I know that we needed for Renesas BSP a certain version that had been officially tested, but it should not be as old as 14.04 anymore. I will check.
- Manu: We should add a target for emulator
- Gunnar: Agreed, this is needed.
- Stefan: There should be a lunch target named genivi-x86 something that will build OK for the emulator.
WBS for VSS-to-Android properties bindings:
- Stefan created a writeup in Markdown → now posted as Wiki Page here.
- Stefan will check about status of the translation code ("manually written example").

- Alex: we are using Apollo graphql server which needs an addition for web token management, and other stuff we are working on, I have discussed which contribution we could do with Markus
- BMW has the blue box on the right box (authentication) (look at the EDS architecture diagram)
- BMW has only the EDS implementation, not the Internal Data Server one
- Alex: the permissions are not yet what we need
- discussion on the work to do for the authentication and the access control groups
- Gunnar: we need to do a more formal description of things to be done for the authentication
- Alex: might be able to do some work in the next days, will try out my ideas on an actual implementation, as soon as I have something (next week possibly), I will generate some docs like ppt
- Alex: tooling is not clear for me yet, as soon as we agree on the way to specify things, we will talk about tooling and manifest generation
- discussion on the naming of artefacts
- Alex: we want to have a nodeJS graphql implementation running
- Alex: I can describe the nodeJS and graphql installation and the deployment of json files
- Gunnar: the wiki page for documenting tihs is AASIG: Implementation notes
- /TODO/ Alex to describe the nodeJS and graphql installation in the above wiki page
- Stefan: at Alex, since you have the authentication implementation under way, could you spent some time to describe what you have done so that we can identify the leftovers ?
- Alex: I can explain that, for instance we need a json web token implementation
- /TODO/ Alex & Stefan to clarify what could be the contribution of BMW & Tieto to the authentication mechanism implementation
