Hi all,
The W3C WG for media fragments has published a Last Call Working Draft
at http://www.w3.org/TR/media-frags/ .
The idea of the spec is to enable addressing sub-parts of audio-visual
resources through URIs, such as http://example.com/video.ogv?t=10,40
to address seconds 10-40 out of video.ogv. This is relevant for use in
the <audio> and <video> elements and can help focus the playback to a
specific subpart.
This specification will provide "deep linking" as a standard
specification for media resources.
Incidentally, such functionality is also available at YouTube, see
http://www.google.com/support/youtube/bin/answer.py?hl=en&answer=116618
.
"The Working Group encourages feedback about this document by
developers and researchers who have interest in multimedia content
addressing and retrieval on the web and by developers and researchers
who have interest in Semantic Web technologies for content description
and annotation. Please send comments about this document to
[email protected] mailing list (public archive) by 27
August 2010."
Cheers,
Silvia.
I'd like to chime in here and encourage everybody to review the spec. I
have been participating in the MF WG under the assumption that this is
something we will couple with <video>. From an implementor perspective,
the main (blocking) issue with the spec is that it doesn't define how to
parse a MF URI, so I hope other potential implementors and spec-junkies
will pay some attention to this and comment as appropriate.
P.S. a more relevant example for browsers would be <video
src="video.ogv#t=10,40">, as MF in the query component is strictly a
server-side matter.
