Claim — deployment view

The Claim module covers Claim, three Evidence subtypes (Document, ElectronicRecord, Vouch), VerificationActivity, AssuranceLevel, and TrustFramework. It is the trust-and-evidence substrate of OPDA — every other module’s data ultimately rests on Claims with attached Evidence and a measurable AssuranceLevel.

Source TTL(s)

File	Role	Physical-Ontology tier
`opda-claim.ttl`	TBox: Claim, Document/ElectronicRecord/Vouch Evidence, VerificationActivity, AssuranceLevel, TrustFramework	claim/classes.md
`opda-claim-shapes.ttl`	Identity-key + IC-breach shapes for Claim, Evidence, VerificationActivity	claim/shapes.md
`opda-claim-annotations.ttl`	DPV baseline (evidence may carry PII; provenance)	claim/annotations.md

Named graph(s)

Named graph IRI	Source TTL	Triples	`owl:versionIRI`

Load order: TBox graph imports foundation + vocabularies. Claim is the second-largest business module by triple count (158 across three TTLs) after Property.

Derived-profile membership

Profile	`opda-claim.ttl`	`opda-claim-shapes.ttl`	`opda-claim-annotations.ttl`
opda-validation	included (classes + properties + subClassOf + labels)	included (all triples)	excluded
opda-ui	included (all triples)	included (all triples)	included (all triples)
opda-inference	included (classical-logic axioms only)	excluded	excluded

Overlay bindings

No overlay currently targets Claim classes directly. BASPI5’s Property + Address + LegalEstate shapes reference Claim transitively (any BASPI5 field that requires evidence — e.g. EPC certificate proof — points at opda:Claim via opda:hasEvidence), but no Baspi5_ClaimShape exists.

A future Land Registry conveyancing overlay or trust-framework-specific overlay (e.g. DIATF Trust Mark scheme) would be the natural first overlay to target opda:VerificationActivity and opda:AssuranceLevel directly.
