VDM update

@Daniel Alvarez-Coello

• New exporter Vspec to S2DM
  Feat/s2dm exporter by jdacoello · Pull Request #463 · COVESA/vss-tools

• First MODULAR full version of VDM pushed to the repo: vdm/spec at main · COVESA/vdm

VDM communication plan

@Paul Boyes

• @Daniel Alvarez-Coello Clarity is missing:

  • TODAY:

    • Two artifacts:

      • Modeling approach → Vspec (YAML-based + COVESA extensions) → i.e., not an standard language outside COVESA

      • Controlled vocabulary (aka., catalog) that results from using that approach → VSS catalog (using YAML format)

    • Ground truth of the logical and conceptual layer: Vspec

      • GraphQL is just an export format

  • VISION:

    • Two artifacts:

      • Modeling approach → S2DM → Reuses Established standard language (GraphQL SDL)

      • Controlled vocabulary (aka., catalog) that results from using that approach → VSS catalog (using GraphQL format)

    • Ground truth of the logical and conceptual layer: GraphQL SDL

      • Vspec is just an export format → backward compatibility (for those mappable features)

Color Legend:

This has to be upgraded → i.e., it will evolve

The information here won’t change → it will only be persisted in a different format
