We recommend media type owners to harmonize their existing schemes with the ones proposed in this document and update or add the fragment semantics specification to their media type registration."

Is there a plan to get that recommendation implemented?

I can offer to do an update of the Ogg RFC http://www.ietf.org/rfc/rfc5334.txt with these fragment specifications.

Though, to be honest, it will be easier to just get implementations and then, if they catch on, update the RFC.

Well, that's a plan of sorts... but it's important to coordinate that with the IETF. It's not polite for W3C to unilaterally encourage implementations to deploy certain designs that will constrain updates to IETF RFCs. I wonder who to coordinate with from the IETF side... The http://www.alvestrand.no/mailman/listinfo/ietf-types page says it's owned/run by Harald Alvestrand and Mark Baker (distobj). Does this play make sense to you? Otherwise, Mark N., would you suggest anybody in particular to coordinate with?

The reason that we can do implementations without much issues is that virtually no other implementations of fragment schemes on media resources exist. Even where schemes were developed such as at YouTube, these schemes were not done on the media resource, but on the Web page URLs. Also see http://www.w3.org/2008/WebVideo/Fragments/WD-media-fragments-reqs/#ExistingS... for a more indepth analysis of the state of affairs. The exisiting MPEG scheme has not been implemented anywhere FAIK and would not clash since it always starts with mp().

Cheers, Silvia.
