David, Thanks for your input. I have updated the 3 tables (3GP, MP4,MOV) accordingly, with the small differences you mentioned for "ma:description" and "ma:samplingRate" These are now ready to be integrated into the spec. Please review and let me know if you are fine (there are a few question marks which should be resolved: (RFC ????, use MPEG-7, perhaps?) About your issue on the column 'relation', Relation: the semantic relation. Possible values are: more specific, more general, related, exact, non applicable (N/A). see for example http://dev.w3.org/2008/video/mediaann/mediaont-1.0/mediaont-1.0.html#metadata-mapping-table 3GP table: http://www.w3.org/2008/WebVideo/Annotations/drafts/ontology10/CR/test.php?table=containerGP MP4 table: http://www.w3.org/2008/WebVideo/Annotations/drafts/ontology10/CR/test.php?table=containerMPEG4 MOV table: http://www.w3.org/2008/WebVideo/Annotations/drafts/ontology10/CR/test.php?table=containerMOV Best, thierry Le 28/09/2010 19:19, David Singer a écrit : > Hi guys > > I filled out the table for 3GPP, and for 99% of the time this also supplies information for MP4 and Movie files as well. > > For all these, the only XPath I know that is defined is selecting a track; in 3GP, MP4 and Movie files, tracks may be identified by track ID, using the ISO/IEC 21000-17:2006 "ffp()" syntax (#ffp(track_ID=101), for example). > > The one item that differs between the formats is 'description'. In 3GPP, this is the dscp user-data item. In 'classic' movies, it's probably İinf (information about the movie); but the language codes and text encodings used in classic user-data would need some ... exploring. MP4 files have no native format for expressing this, unless you consider MPEG-7 such. > > > I made the table in Excel; if this is the right information, and the right level of info, Courtney and I could work on getting it into HTML.
