Groups, rooms and expert attestation into the record. Named voices, on the record.
Groups and rooms where named people sign credentialed utterances. Posts, comments and votes on DRM3 identity; later, expert attestation into the fact record. A certified attestation is an utterance, never an origin.
The studio desk. Films, spots and video editions, cut from the record and signed.
Every picture, film and record the studio makes, with its hash and its licence.
A commercial that can be checked. Every page photographed where the quote lives.
