v0.1.0
90f8537

First public working draft of the SIGNET Canonical Data Model — the open standard for governed procurement networks, stewarded by Concert Foundation. Licensed CC0 1.0.

This is a draft published for community review. Field-level definitions illustrate the model's shape and are not yet frozen.

What's in v0.1.0

  • Foundation layer: Identifier, Party, Value, Period, Classification, Item, Credential, Document, Provenance, Score
  • Process layer (initial): SourcingEvent, Submission, Policy
  • Agent layer: SyntheticAgent, Mandate, Decision — synthetic agents as first-class, governed, accountable participants
  • Trust layer: Event, Consent
  • JSON-LD @context aligning to ePO, PROV, and W3C VC
  • Closed and open codelists (CSV), worked examples, and CI validation

Notes

  • The JSON Schema is the source of truth. Where prose and schema disagree, the schema wins.
  • Targets JSON Schema Draft-07 for tooling compatibility; a move to 2020-12 will be considered before v1.0.
  • Profiles and bridges to OCDS, EN 16931, UBL/Peppol BIS, W3C VC/DID, and the EU eProcurement Ontology.

Feedback welcome via issues and discussions. See CONTRIBUTING.
