- 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).

- 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.

- 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.

Refocusing of project
- Philippe: IMHO we need to refocus the project activities, more OEMs are now working with Google, we need to recognize this and consolidate the knowledge the VHAL team has been building during the past year. I would recommend we revisit the work breakdown structure and the priority of activities
- Stefan: we should now analyze how to provide all vehicle properties through VHAL rather than through graphl, this means to look into the generation of bindings / the translation from VSS to vehicle properties
- review of the existing work breakdown structure (for the External Data Server concept)
- Stefan: I will check the architectural concepts we came up with in the past and propose another architecture to work on

- discussion on abstract, Stefan will work out an abstract and submit it by the end of the week DONE
- abstract text is the following
- title: Vehicle Signals access from IVI systems in generic way
- abstract:
- Accessing the Vehicle Network in a secure way is a challenge that each Automotive vendor and supplier must cope with. Rich collection of modern Operating Systems is approaching the industry and develop a need to have a standard approach to be reused across them. GENIVI Android Automotive Special Interest Group for Vehicle API is aiming is to provide a community voice and solution for generic challenges by example implementation. The presentation is a brief overview of the current progress of the common components that allows the vendors to move the effort needed for implementation to configuration of existing components.
- Agenda
- Android to utilize Vehicle Data Standard to access the Android Signals
- Current architecture
- Project setup (Environment setup references)
- Components overview (repositories, the purpose of each component)
- Access control and “external data server” for properties – outside Android
- Derived activities
- Apollo GraphQL as server – resolvers implementation
- Client implementation using Apollo GraphQL Java Client Library for Android
- VSS to Android properties translation
- Current challenges
- Way to describe the mapping between AOSP properties and VSS leaves – proposal and complexity of the solution
- C++ code generator to translate the properties
- Current challenges

- Gunnar, Stephen, Philippe: attended Fosdem several times, this is the most important event for open source developers worldwide, a good place to get known and to recruit developers
- TODO Stefan to check with Tieto whether a talk could be submitted
- deadline for submitting a talk is 23 December
- discussion on talk content
- there is a consensus that the VHAL demo development platform is a good topic since it is important to talk about code implementation at Fosdem
code implementation
- Stefa: not much done since last week's code publishing
- Gunnar: what is the open question on licensing you mentioned ?
- Stefan: there is still no license file in the github repo
- Stefan: Apache 2.0 is Tieto preferred license (it is AOSP preferred license).
- Gunnar: this is fine
- Stefan: we need to complete and finalize the demo platform for Q1, 2021
content of next version of the demo
- Stefan: we need to show the permission control promised by Alex, this is an important piece of code for the data server, it will allow us to validate the currently used EDS architecture, before digging into other architectures as suggested by Chris
- Gunnar: I agreed we need access control
- Gunnar: we will then have an opportunity to build other variants of the architecture and use a translation of VSS into vehicle properties, the initial work on translation can start now
- Philippe: suggests to have a working session on the translation next week (instead of having an all hands report which can be done with a slide deck distribution)
- all agree this is a good proposal
- Gunnar, Stefan and al. will prepare the working session via the mailing list

Tuesday 1 December - 500pm CET
...
- 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
