I'd suggest at some point to look into separate stream solution for
metadata, perhaps M3F [1].

Yeah - there's a whole swag of different types of related text that
needs to be regarded, not least of which are:

    * CC: closed captions (for the deaf)
    * SUB: subtitles
    * TAD: textual audio descriptions (for the blind)
    * KTV: karaoke
    * TIK: ticker text
    * AR: active regions
    * NB: metadata & semantic annotations
    * TRX: transcripts / scripts
    * LRC: lyrics
    * LIN: linguistic markup
    * CUE: cue points, DVD style chapter markers and similar
navigational landmarks

As for non-time-aligned metadata, vorbiscomment has so far served us
well, not least because it's extensible. There is also XMP, and a
whole swag of other metadata schemes. Plus, the W3C is currently
investigating a new ontology for video/audio metadata. This may be a
good extension for vorbiscomment once finished.

Cheers,
Silvia.

Ooh, can you say anything about it? Are there any documents up yet?
I've been waiting for something better than rdf xml for a looong time. :)

RDF has a very different purpose. After having been at the W3C
meeting, I am actually starting to understand the Semantic Web. It's
merely like a database of information that is available for everybody
to add to and to take information out of. ;-)

As for video metadata, there is the W3C media annotations working
group http://www.w3.org/2008/WebVideo/Annotations/ . Likely, it will
develop a "structure" of standard metadata fields for audio &
video.
This may be structured. It may have an RDF XML representation, but
certainly not the only one. What I am most interested in are the
fields that will be defined. Currently, Adobe's new XML
http://www.adobe.com/devnet/xmp/ is under investigation as a means to
provide a basic set of fields.

Cheers,
Silvia.
