Wanted to let you that the C2PA draft spec has been updated. Besides the technical spec updates, it also includes new documents for Guidance, Explainer, User Experience, Threat, and Harms. The draft specification can be accessed through the C2PA website, and comments can be provided through a web submission form, through GitHub, or through PM.
We have already implemented several aspects of the new draft in our Marketplace we are developing. See the area below the image of the screenshot in the header and compare it to Section 5.4 of the User Experience document https://c2pa.org/public-draft/UX_Recommendations.html#_non_editorial_transform.
