Owning creative-work, publication or edition, recording, image, scene, broadcast, party, agreement, rights instrument, credential, storage system, service or decision lifecycles
Treating filename, URL, storage key, checksum, metadata block, credential, best-copy label or publication endpoint as universal media identity
Inferring originality, factual truth, ownership, copyright, permitted use, accessibility or fitness without source-qualified evidence
Publishing, granting rights, disclosing protected content, mutating external systems or irreversibly deleting bytes without accountable authority

Why it exists Filled

Distinguishing features Filled

Manages a media asset and its renditions as technical representations, not the creative work they express.
A filename, URL, storage key or checksum is not the identity of the asset.
A checksum proves fixity of bytes, not authenticity, origin or rights.
A content credential is a provenance signal, not proof of truth or copyright.

What robots and AI may and may not do Filled

Must not

Publish a rendition.
Grant or assume usage rights.
Irreversibly delete bytes.
Disclose protected content.
Present edited media as authentic.

Only with a human decision

Publication and rights decisions.
Deleting a preserved rendition.

May

Extract technical metadata and identify formats.
Calculate and verify checksums.
Create derivative renditions such as proxies or thumbnails.
Validate files against format profiles.

Moral aspects Filled

Media often depicts people who did not consent to its use.
Synthetic or altered media can mislead audiences.
Accessible renditions such as captions are needed for people with disabilities.

Who is affected

People depicted in media
Creators and rights holders
Audiences
Archives and memory institutions

Owners Filled

Steward

Declare the Dimension owner, media-asset master, rendition registrar, metadata steward, preservation custodian, rights authority, accessibility reviewer and auditor.

Roles

Dimension owner: Own namespace, mastership, delegation, access, retention and federation rules.
Media asset steward: Own asset aggregate identity, rendition graph, roles, lifecycle and correction policy.
Rendition or technical metadata registrar: Own representation identity, bytes, formats, characteristics, components, fixity and validation evidence.
Creator, producer or processing operator: Own attributable capture, ingest, edit, transcode, render and export activities and settings.
Rights and publication authority: Own rights bindings, license interpretation, embargo, territory, channel and accountable publication decisions.
Preservation custodian: Own copies, storage, fixity schedules, migrations, retention, holds and recoverability evidence.
Accessibility and quality reviewer: Own profile-qualified accessibility, technical, perceptual and fitness assessments.
Security, privacy or authenticity reviewer: Review sensitive metadata, credentials, bindings, trust policy, encryption and protected disclosure.
Auditor: Review identity, lineage, rights, lifecycle, corrections and destructive actions without rewriting originals.

neighbor

WM-MED-001 Creative Work / Content - The registered parent owns abstract intellectual content and authorship. This model owns the operational aggregate and concrete technical representations without making the work and its encodings one identity.
WM-MED-003 Publication / Edition - A publication or edition owns release and edition identity, audience and publication context. It may select media renditions but does not replace their byte, format, lineage or preservation identities.
WM-MED-004, WM-MED-005, WM-MED-006 and WM-MED-007 specialist models - Audio/video, image/graphic, 3D/scene and broadcast/stream models extend medium-specific semantics. The present aggregate keeps only shared format-independent representation controls.
WM-MED-008 Content Authenticity Credential - A credential binds signed provenance assertions to an asset or rendition. It has its own issuer, manifest, signature and validation lifecycle and cannot become asset identity or prove semantic truth.
File, bitstream, fragment, service, locator and storage copy - These are technical representations, parts, access mechanisms or holdings. Mutable locators and storage placement never replace stable asset and rendition identity.
Rights instrument, ownership, custody and permitted use - Copyright, ownership, license, policy, possession, custody and publication authority are distinct external assertions. Technical control over bytes does not establish legal authority.

Open questions

Version-pin and live-URL audit: Verify DCMI living spec freeze date, confirm IPTC Photo Metadata 2025.1 and C2PA 2.4 publication status, test all 24 source URLs for accessibility, and document which W3C Recommendations are stable vs. living standards.
Cardinality and optionality rules: Specify minimum-required vs. recommended vs. optional fields for different rendition roles (e.g., does a thumbnail require full lineage? does a preservation master require rights binding?). The structure is comprehensive but doesn't declare operational minimums.
Cross-model composition verification: Validate relationship contracts with WM-MED-001 Creative Work (work→asset cardinality), WM-MED-003 Publication (edition→rendition selection), WM-MED-008 Credential (binding modes), and specialist media models (inheritance vs. delegation patterns).
Metadata precedence policy: Document resolution algorithms for embedded vs. sidecar, signed vs. unsigned, catalogue vs. technical, and time-stamped metadata conflicts. The model structures the evidence but doesn't specify the decision logic.
Format risk and migration triggers: Expand preservation coverage with concrete format-obsolescence indicators, migration-trigger policies, and conformance-validation test suites referenced but not detailed in the current PREMIS/AudioMD/VideoMD citations.
Image, audio, video, document, 3D, immersive, broadcast, streaming, archive and sector-specific technical profiles require specialist review.
Creative works, publications, recordings, images, scenes, broadcasts, parties, storage services, agreements, rights instruments, credentials and decisions remain neighboring masters.
Patent- or license-restricted codec conformance, broadcaster delivery specifications, platform moderation rules and jurisdiction-specific rights require separately pinned profiles.
Automated rights grants, public release, authenticity conclusions, irreversible deletion and identity merge remain outside unreviewed agent authority.
