- ... and the exact interface if it is a RPC protocol (i.e. reference a "VSC interface")
- ... and a common methodology for permissions definitions.
permissions:
vis:
Attribute.Body.Vehicle.VIN : "r"
Attribute.Body.Vehicle.VIN : "r"

Related projects walkthrough (every week):
| Project | Person reporting | Updates |
|---|
| Sebastian (Bosch)  | Sys arch documentation to clarify use of VISS for reading and writing data (ref previous week's discussion) https://github.com/eclipse/kuksa.val/blob/master/doc/system-architecture.md |
- W3C VISS specification (v2)
| Ulf
Ted as backup | No discussion about spec
(presentation MongoDB instead) |
- VISS server implementation in Go
| Ulf | Nothing this week. |
| Daniel Wilms (BMW)
(Gunnar, Sebastian as backup) | Removing min/max in standard catalog because they appeared arbitrary. Added new signal for SAE autonomy level.
Tools versioning , and how it relates to versioning of VSS standard catalog
Recommendation for allowed_values names/strings. Used in standard catalog (whenever it is possible to define it from scratch, not constrained by system already). |
| Daniel W
Ted | Switched to W3C reSpec tooling. New version including signal definitions derived from VSS catalog. First public working draft hopefully within a week or so. Discussed W3C workshop (virtual) in early March and/or in-person meeting in combination with COVESA AMM (Leipzig, end of April) |
| Gunnar | Narrowing down tech solution to promote Franca IDL + YAML format as core description format. (Strategy to allow interchange with other technologies of course still in place)
Increase catalog scope with more proposals to gather interest. |
| Ulf | Nothing new |
| Artem
|
|
- Android Automotive VSS→ Vehicle Properties
Code Generator
|
| Maintenance may be taken over by Stefan at TietoEvery |
Eclipse Kanto
(proposed. worth tracking in CVII call?) | (Thomas S) | Possibly focus next wednesday? |
Minutes
- Project update (above)
- AOS update, more comprehensive:
- AOS code now in GitHub.
- Apache License
- Framework to orchestrate containers
- Several services in different repositories
- Working on code coverage for CI tests
- Follow the README documentation
- Already used on some production projects
- May lead to standards for orchestration, control, etc.
- This covers all the software that runs on the embedded systems
- meta-layers for Yocto
- Thomas: Can we get a demo? To understand the concept better?
- Artem: If you have a Renesas starter kit or similar. You can also try it in a VM on desktop. Yes to demo (in a week or two)
- Artem: We have our own CNI for plugins, firewall, = networking configuration for containers.
... not using docker.
...Using crun currently (previously runc but now crun). - ...Working on introducing standard K8S APIs
- Artem: Data side, we wish to stay with CVII work and VSS specifically
- Artem: We have a YAML based description format. Also monitoring any OCI standards that may apply
- Gunnar: As noted we should set up a time to discuss overlap of the services description format in AOS and VSC.
Gunnar/Artem: Agreed joint desire to consider service description ability using a common language, as VSC project intends to achieve.
- For information: Data Privacy Initiative
- COVESA is discussing a Data Privacy oriented project (led by member companies in the legal space)
- Overview of current rules and regulations, legal risks, counteractions.
- Create an environment of collaboration to discuss these aspects, in general terms.
- This topic requires a combination of business management, legal, technical, ...
- Please reach out to your colleagues (including management, legal) to evaluate interest
- Likely webinar/Q&A discussion in Feb/March + focus in AMM
- Meeting CCS → tech architecture.
1. Meeting 1? – 30 min overview. 30 min any other topics
2. Meeting 2? – Technical work? Is it implementation focus? Architecture focus?
Agendas are important
One slot is shorter?
Thomas: Workshop planning - 1h not enough. (4h, less frequently)? - Ted: Possibly fewer calls instead?

Apologies
Agenda/Minutes:
- Sebastian: GitHub Packages are recommended, for container images for example.
- Stephen: Common implementations? E.g. AOS has VISS server, KUKSA.val has VISS server, etc. Upgrades to latest protocol version - shared implementation?
- Alexander: Additional code is coming from BMW (ref: last week's walkthrough). The implementation of the actual GraphQL server is coming next.
- Further discussion on how to organize joint development projects:
- Provide feedback to component names in: CVII Tech Stack Terminology - temporarily stored on GENIVI Wiki:
- Also read (again) Towards CVII pluggable components and consider if these are obstacles to collaboration, and which ones we can overcome.

- Walkthrough of existing repos, reasons and intentions behind.
- Live demo
- Create GraphQL schema with tool
- Only a single Query / entry point that is matched against the whole Vehicle Tree. GraphQL schemas can define multiple, but this is how it is done here.
- Subscription queries are supported
- Query can include all values of any (sub)type in the tree, or only some, it is very flexible.

| Project | Person reporting | Updates |
|---|
| Mike Haller (Bosch) Thomas Spreckley | Further development of these components (from Bosch side)
has been halted in favor of building a new infrastructure based on DAPR framework
Rules engine in iot-event-analytics still of interest - either reuse or write similar functionality into DAPR CES demo |
| Sebastian (Bosch) | Plans are unchanged (not more, not less). Small feature sprints. Still being maintained.
|
- VISS server implementation in Go
| Ulf | Nothing this week. Will be updated soon due to latest changes in VISS spec. |

| Gunnar | Nothing this week (biweekly sync meeting) - see last week's minutes Bosch interface tools - see minutes below |
| Ted Ulf | Additional updates on access control:
- Optional usage of vehicle-identifier in security tokens. (Optional when not required such as inside-vehicle access
- only one vehicle is relevant, the one that is "connected")
... but mandatory when required - e.g. access from cloud to (many) vehicles. - One new flow in access-control model. Low-complexity flow (PR coming) |
| Ulf | Updated images in README explaining the usage of different component parts |
| Artem

Apologies
- Ted – conflicting meeting
Agenda/Minutes:
- Project updates according to above table
- Ted and Gunnar will be presenting W3C, COVESA, CVII and VSS on a Workshop on Future Automotive Research Datasets, organized by SRI international
- Thomas: Bosch preparing a presentation of interface-related tooling (OpenAPI) to VSC meeting for alignment of IDL needs and definition. The example will be modeling comfort services.
- First code repositories created for GraphQL (and more) related tools from BMW.
- The code is ready to go, but unfortunately the responsible has become ill, so we're waiting for the first code push still.
Planned content:
test-someip-service
- Example interface for showing the mapping from GraphQL-server to SOME/IP signal source
test_franca2vss_mapping_layer - Proposing a VSS layer format to define where each VSS signal can be fetched, from a service interface described by Franca IDL.
(similar to the ideas in the ongoing VSS-to-Android mapping files)
vss2graphql_schema - Tool (generator) creating GraphQL schema definition from a VSS catalog. (Possible inclusion into vss-tools later on)
- DAPR - looking at connection points
- (Renesas) - Started development of internal-simulator2VSS mapping job, and Apache IoTDB implementation.
- Who's behind this, who created, maintain... ? Renesas?
- Stephen: It was created at a Chinese university before being contributed to the Apache Foundation.
- A natural? choice for an embedded time-serie
- s DB (if you need that).
- Strong connections to other Apache tools.
- AVRO serialization status on this branch
- Proposed: (shared) C++/and-or other language library - client library / convenience API for data serialization.
- Reminder: Gunnar update CCS-component picture with proposed changes.
