7th December 2022

EG project announcements
- Update on Autosar Collaboration
Xmas break
- Steve can only remotely phone in next week, which would be the last meeting before Xmas. Nic can't make it.
- Decision taken to break for Xmas early. This is the last meeting of the year. Thanks to all who contributed.
- Request: think about the Design Pattern goals over xmas
Data Arch Theme discussion
- Proposal to hold a virtual workshop for multiple hours early next year to accelerate the design pattern discussion.

Project status
- Majority of VSS call taken up with VSS struct support discussion. Best practices good/bad one of the focus points next.
- Ted summarised VISS/VSSo updates
Data Arch Theme discussion
- GraphQL
  - Andre: Nice for query. Problematic to have generalised set method. Have to do heavy development in schema for setter. Complicates cross vehicle model support.
  - GraphQL still of interest in the tech landscape but VISS is the more obvious first priority
- Discussion of existing high level in-vehicle data architecture diagram. What it was created for and its limitations.
- Ulf showed how his V2C proposal could address data needs
- (Data) Design Patterns
  - Discussion of in-vehicle architecture leads back to the existing topic of local data reduction at the edge/within function and smart exchange between functions
    - Local processing generating higher logic data possibly at lower frequency, e.g. engine management does local monitoring and then externally reports decisions
    - Reduces in-vehicle network traffic
    - Reduces costs associated with data transmission to the cloud
    - This is an obvious candidate for a design pattern: benefits, how it may be done, VSS/VISS role in that.
