2025-07-31 Meeting notes

Updates

@Paul Boyes 

• Board meeting happening Aug 13, 2025 , road map is needed.

• Are we targeting the people we want to be part of this?

  • First, current participants should get familiar with this approach (and possibly hands-on).

  • Once we get to a stable state of the repos, we can integrate more people.

  • Stronger alignment with VSS is encouraged. 

• VDM repo? → It is public already.

  • Agreement to coordinate on transportation/geospatial/vehicle ontologies across OpenGeospatial Consortium (OGC), W3C and ISO Intelligent Transportation Systems, started a registry
    UToronto and OGC does more in the open, most ISO behind paywall and there was intent to open those - some leaked (deliberately) through eg github

  • SAE J1939 Digital Annex - Tom Feller (Daimler, NA) joined COVESA Commercial Vehicle call
    discussion around alternate, logical structuring besides current physical based tree of VSS
    explained VDM ambitions and learned of schema work, got down into weeds on various topics including broadcast frequency of signals - metadata we need to represent

  • J1939DA specs I have access to internally are older and not current 2025 drafts, meaning we are not in that committee. I am a SAE Member and asked to join
    Introduced Tom to Daniel Alvarez and want us to explore further with them

Next sessions during summer brake?
