Proposal: Publication Status Values for OAA 1.0

Status

Accepted for OAA 1.0; additional values deferred

Summary

Retain only published_art and unpublished_art as base publication_status values for OAA 1.0.

Motivation

Additional publication states need shared definitions. An uncertain or more specialized source value should not be forced into a misleading base value.

Specification Changes

• The existing closed value set remains unchanged.
• Writers MAY omit the optional publication_status field when the status is unknown or cannot be mapped faithfully.
• Writers MAY preserve source-specific publication information in namespaced extensions.

Compatibility Impact

No vocabulary change for OAA 1.0. Under the versioning decision, adding a closed-set value after 1.0 requires a new major schema version.

Examples

An artwork with uncertain publication history can omit publication_status while retaining that uncertainty in descriptive text or an extension.

Open Questions

No open question blocks OAA 1.0. Additional values are deferred pending community consensus. Structured publication details remain a separate deferred proposal.
