attested subject

• CURIE: gmeow:attestedSubject
• IRI: https://blackcatinformatics.ca/gmeow/attestedSubject
• Category: property
• Defined by: gmeow:slices/attestation
• Box roles: CBox role, RBox role (What is this?)

The entity that an attestation is about — the thing being vouched for. Non-functional: an attestation may concern multiple subjects (e.g. a key↔identity binding certifies both a key and an identity), and competing subject claims coexist (Principle 9).

Structure

Property shape: object property; gmeow:Attestation -> gmeow:Entity

Practical Pattern

Use gmeow:attestedSubject from gmeow:Attestation to gmeow:Entity when the relationship itself belongs in the native GMEOW graph.

# Worked example: a supply-chain attestation. A gmeow:Attestation binds an
# gmeow:attester (who vouches) to an gmeow:attestedSubject (what is vouched for)
# under an gmeow:attestationType drawn from the open vocabulary of real formats
# (SLSA provenance, in-toto, DSSE, C2PA, verifiable credential, …). Here a CI
# pipeline issues a SLSA-provenance attestation over a release bundle, carries
# the signed artifact, and a relying party records a gmeow:VerificationResult —
# the attestation is a claim; verifying it is a separate, recorded act.

Usage Advice

Use when

• Use to name the bare entity an attestation vouches for — an artifact, a key↔identity binding, a release — when the subject is a thing rather than a reified claim.

Avoid when

• Avoid when the subject is itself an observation or claim (use gmeow:attestedClaim, whose range is gmeow:Observation) and for the issuing agent (gmeow:attester); read the entity-rooted inverse via gmeow:hasAttestation.

How to use

• Point the Attestation at one or more subject entities; an entity reaches its attestations through the inverse gmeow:hasAttestation, and competing attestations about the same subject coexist (Principle 9).

Examples

• ex:relAtt gmeow:attestedSubject ex:release1_2.
