LinkML Vocabulary, OWL 2 Ontology & Normative JSON Schemas

This repository ships machine-readable vocabulary and schema artefacts aligned with ISO/IEC 38505-1:2026, ISO/IEC 25012:2008, the Eclipse Dataspace Working Group (linkml/cap.yaml), and Gaia-X (odrl-vc-profile):

  1. W3C OWL 2 Ontology (1_NORMATIVE_SPECIFICATION/ontology/ontology_graph.owl):
  2. Formalises the 5-Plane Constitutional Stack (SovereignDefinition, Dimension, Rule, Metric, Process, ContextBinding, SemanticCertificate) grounded in ISO/IEC 38505-1:2026, ISO/IEC 25012:2008, W3C ODRL 2.2, and W3C PROV-O.
  3. LinkML Dataspace Ontology (1_NORMATIVE_SPECIFICATION/ontology/odgs_dataspace.linkml.yaml):
  4. Defines AuthoritativeSource (exact_mappings: [cap:SpecifiedRequirement, prov:Plan]), ExecutableRule (close_mappings: [odrl:Rule, ovc:Constraint]), ProcessBinding, and SemanticCertificate (close_mappings: [cred:Evidence, prov:Entity]).
  5. JSON-LD Context (1_NORMATIVE_SPECIFICATION/schemas/odgs-dataspace.context.jsonld):
  6. Maps odgs: properties directly to odrl:, cred:, prov:, cap:, and ovc: namespaces.
  7. Normative JSON Schemas (1_NORMATIVE_SPECIFICATION/schemas/):
  8. 01-metrics-schema.json & legislative/standard_dq_dimensions.json: 60 data quality dimensions mapped to ISO/IEC 25012:2008 (iso25012Characteristic), ISO 8000-8, ETSI EN 304 311, and ISO/IEC 38505-1:2026 (iso38505GovernanceFacet).
  9. 02-rules-schema.json: Deterministic validation rules (HARD_STOP, SOFT_STOP, LOG_ONLY).
  10. 03-ontology-schema.json & executive/context_bindings.json: Contextual process bindings (ISO/IEC 38505-1:2026).
  11. 04-s-cert-schema.json: Validates both Level 1 (Core Conformance) and Level 2 (Attested Conformance) S-Cert receipts, including correlation_id, jws_signature, authority_id, and issuing_jwk_url.
