attestation type

The type of attestation being made — a value vocabulary individual from gmeow:AttestationType. Non-functional: an attestation may carry multiple type tags (e.g. both SLSA provenance and DSSE envelope).

Structure

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

Practical Pattern

Use gmeow:attestationType from gmeow:Attestation to gmeow:AttestationType 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.
