    digest

    https://opda.org.uk/pdtf/digestTurtle ↓

    Relates a claim or piece of evidence to its cryptographic hash, expressed as an algorithm-qualified digest value drawn from the digest-algorithm concept scheme.

    Cryptographic digest of a Claim or Evidence (algorithm + value, e.g. 'sha256:e3b0...'). Local term per S009 5-residue (PROV-O has no notion of signature or hash). Algorithm validation by opda:DigestAlgorithmScheme SKOS scheme (ADR-0012 emits the constraint).
