Structure

Property shape: datatype property; gmeow:CryptographicKey -> xsd:dateTime

Practical Pattern

Use gmeow:keyExpiresAt from gmeow:CryptographicKey to xsd:dateTime when the relationship itself belongs in the native GMEOW graph.

Common Companion Terms

gmeow:CryptographicKey

Usage Advice

Use when

• Use to record when a key is scheduled to expire — the self-declared validity bound carried in the key's own metadata.

Avoid when

• Avoid for the validity window of a certification or trust assertion (those use gmeow:validFrom / gmeow:validUntil on the relator) and avoid forcing one value — sources and subkeys report different expiry, so keep it non-functional.

How to use

• Attach the expiry instant as xsd:dateTime; carry the holding or attestation windows separately on gmeow:holdsKey and gmeow:Certification, and let competing source expiries coexist.

Examples

• ex:lillithKey gmeow:keyExpiresAt "2027-01-01T00:00:00Z"^^xsd:dateTime.
