Usage Advice

Use when

• Use to record the IANA media type of an attestation artifact's serialization, so a consumer can dispatch the right parser before re-verifying it.

Avoid when

• Avoid for the broad attestation kind (gmeow:attestationType, e.g. SLSA provenance) — the media type is the wire format string, not the attestation category — and avoid two values, since it is functional.

How to use

• Set one media-type literal on the gmeow:AttestationArtifact; pair it with gmeow:attestationType on the Attestation so consumers know both the format and the kind.

Examples

• ex:inTotoJson gmeow:artifactMediaType "application/vnd.in-toto+json".
