Is there anything we should/could add on TDM? #29

I do not know what the intentions of the relevant CG is in terms of standardization. To be clear, I do not propose to get TDM through the W3C standardization route (I do not think this would be appropriate in terms of scope), but we may want to say something about how the TDM (or C2PA?) information should be incorporated into EPUB.

TDM Reservation Protocol properties are included in EPUB per the current specification's extensibility rules. Therefore, there is no requirement for evolving the EPUB specification to include these properties in an EPUB file.

Now, should the TDM Reservation Protocol take the W3C standardization route via the Publishing Maintenance WG (which is not limited to EPUB evolutions)? I believe the answer belongs to the Publishing Steering Committee.

TDMRep is a set of rules related to protocols (HTTP) and content formats (HTML, EPUB, PDF etc). There is currently an initiative to model TDM opt-out solutions (i.e. create a common vocabulary) in the IETF circle. TDMRep is an implementation of such model, C2PA is another. Where will implementations be standardized after they are refined? If W3C members are not interested in HTTP rules, this part could go to IETF, etc.

If you want to make tdm a reserved prefix so that it doesn't have to be declared, that would be worth taking up. It would likely be a class 4 change since it would require epubcheck and reading systems to accept the undeclared prefix.

I do not think this should be done; it feels very much out of scope for my taste. TDM is not for publishing digital books only; it is for publishing any kind of data on the Web.

To avoid misunderstandings: I am not against TDM being standardized in W3C, but it should be chartered as a separate WG in my view. (Chartering will be a difficult project, though, it will have to justify itself against C2PA, for example...)
