Media Provenance

Register a derivative attribution

Record that one work derives from another: sample-of, cover-of, sync-into, or ai-training-set-of. Each edge becomes an EAS attestation queryable in both directions by the indexer.

Edge type

What kind of derivation

The edge type determines the EAS schema used. Active forms (sample-of, cover-of, etc.) record the upstream source; the indexer normalizes for downstream queries automatically.

Identifiers

Source and derivative work IDs

Master clearance

If applicable

Sample-of and sync-into typically require master clearance. Cover-of usually flows through MLC blanket mechanical only. AI training uses the posture field above.
