This page attempts to understand the official status of MPEG-21 Part 17 - Fragment Identification with respect to standardisation, and its actual implementation / uptake.

  • Dave Singer points out that the mime-type application/mp21 has been registered in IANA, (see http://www.iana.org/assignments/media-types/application/) on 2008/10/01. Dave is the contact person
  • Cyril Concolato, leader of the GPAC project argues that the ISO Part 17 defines a scheme for fragment identifiers to be used with a any resource of Internet Media Type is one of audio/mpeg, video/mpeg, video/mp4, audio/mp4 and application/mp4. However, these RFCs do not point back to the ISO document

Questions to track:

  • Are you aware of any MPEG implementations that have implemented the fragment addressing schemes?
  • Do you have more information to share on the uptake and use of the MPEG-21 URI fragment addressing schemes?
