In partnership with the IPTC, the PLUS Coalition has published for public comment a draft on proposed revisions to the PLUS License Data Format standard. The changes cover a proposed standard for expressing image data mining permissions, constraints and prohibitions. This includes declaring in image files whether an image can be used as part of a training data set used to train a generative AI model.

Review the draft revisions in this read-only Google doc, which includes a link to a form for leaving comments.

Here is a summary of the new property:

http://ns.useplus.org/ldf/vocab/DMI-PROHIBITED Prohibited
http://ns.useplus.org/ldf/vocab/DMI-SEE-constraint Allowed with constraints expressed in Other Constraints property

If it is accepted by the PLUS membership and published as a PLUS property, the IPTC Photo Metadata Working Group plans to adopt this new property into a new version of the IPTC Photo Metadata Standard at the IPTC Autumn Meeting in October 2023.
