Interesting indeed. I was under the impression that both MPEG7 and MPEG21 registered the fragment syntax together with the MIME type, but obviously they didn't. Ogg/temporal URI only has an expired I-D for this. YouTube, Google and the other Web 2.0 sites that provide temporal media fragment addressing just simply provide it as a feature without registring it. Also please note that RTP/RTSP, while specifying protocol methods for addressing time offsets, have left the URI syntax specification to the server, see http://www.ietf.org/rfc/rfc2326.txt (search for "fragment"). I have just added that information to http://www.w3.org/2008/WebVideo/Fragments/wiki/State_of_the_Art . [Davy/Erik: you might want to add this to the WD]. I agree that we should send letters to all the stakeholders that we have identified and encourage them to use the current specification under development, also encouraging them to give us feedback if they come across any issues. Cheers, Silvia.
