Claim module
Verifiable claims (Claim), the three categories of evidence supporting them (DocumentEvidence, ElectronicRecordEvidence, VouchEvidence with short-name aliases Document, ElectronicRecord, Vouch), the verification activity that produces a verified claim (VerificationActivity), the assurance-level quality judgement (AssuranceLevel), and the trust-framework citation (TrustFramework).
Entity inventory
| Entity | UFO meta-category | Notes |
|---|---|---|
| Claim | Information particular | PROV-O Entity; S009 Q1 80%-PROV-O mapping |
| Document | Substance Kind (informational; alias) | owl:equivalentClass of DocumentEvidence |
| DocumentEvidence | Substance Kind (informational) | Paper / scanned artefacts issued by authoritative source |
| ElectronicRecord | Substance Kind (informational; alias) | owl:equivalentClass of ElectronicRecordEvidence |
| ElectronicRecordEvidence | Substance Kind (informational) | API-retrieved structured records from authoritative source |
| Evidence | Substance Kind (informational) | Generic Evidence supertype; three named subtypes per S009 Rule 5 |
| TrustFramework | Information particular | Governance regime that scopes claim validity |
| VerificationActivity | Event particular | PROV-O Activity producing a verified claim |
| Vouch | Substance Kind (informational; alias) | owl:equivalentClass of VouchEvidence |
| VouchEvidence | Substance Kind (informational) | Formal attestation by a regulated professional |

Class hierarchy
OWL/RDFS subclass relationships. Claim and Evidence specialise prov:Entity. Three Evidence subtypes (DocumentEvidence, ElectronicRecordEvidence, VouchEvidence) each have a short-name owl:equivalentClass alias. VerificationActivity specialises prov:Activity.
