Re: Minutes of the W3C CG meeting of 25th Jan

What you write about Eric, the CAWG, etc. is all true.   The goal of the CAWG is indeed to build on C2PA to bring additional assertions in the area of identity, authorship, & ownership.

The model of having other groups build extensions to C2PA is something we are trying to promote more.  CAWG is one.  The PDF association is working on a set of PDF extensions…

Thanks for the link, Leonard,

I read that this new specification is defined as a draft, maintained by the Creator Assertions Working Group led by Eric Scouten (Adobe), a WG "which builds upon C2PA by defining additional assertions".

I also read that "This specification is not a product of the C2PA itself, so it can not use the c2pa. prefix. Therefore, though structurally similar to the C2PA 1.x definition, the labels have been changed to cawg. in this specification."

ok.

My apologies – thought I mentioined that.

We have moved the TDM assertion to a new group that is focused on identity, authorship and ownership concerns.  Everything remains the same technically, it will simply be managed by another technical working group.   See https://creator-assertions.github.io/training-and-data-mining/1.0-draft/

Leonard - in your answer, you didn't respond to Giulia's question:

Furthermore, it seems that the V2.0 of this specification deprecates the "Training and Data Mining" properties previously defined in the V.1.3.  Could you please point us at the new way of expressing tdm opt-out in C2PA?

Having the opt-out section deeply buried in the current version of the C2PA spec, or worst, absent from this version, could let people think that C2PA is not interested in opt-out after all.
