Resolution status:

Dear Media Annotations WG,

I really like the efforts of the WG to come up with a common
(Internet) media description / annotation ontology. Thanks for your
hard work to consolidate similar efforts!

Two questions:

1) Subtitles
Other than by means of mentioning _external_ subtitles via ma:relation
as in TXFeed...

* TXFeed: <link rel=”subtitle” href=”http://example.org/video.en.srt”
type=”text/x-srt” hreflang=”en” />
* Ontology for Media Resource (if I got this correctly?!):
<http://example.org/video.en.srt> ma:relation
<http://dbpedia.org/property/subtitle> or just
<http://example.org/video.en.srt> ma:relation subtitle (?)

....did you consider allowing for the _embedding_ of actual subtitles
(where subtitles can be movie subtitles, or also song lyrics, or
speech transcripts) into the media description more or less like in
Media RSS's <media:text> (http://video.search.yahoo.com/mrss) element?
This might happen by the introduction of an ma:event container that
could hold the particular time spans, and the actual subtitle

2) Semantic annotation
I'm currently thinking of whether the level of detail of Audio
Description (see http://www.acb.org/adp/ad.html, there: "Samples of
Audio Description") could be expressed with an (this?) ontology. The
main concept would be very similar to 1), however, allowing for richer
annotations than just plain text subtitles including e.g.
<http://dbpedia.org/resource/Audience> example:humanActivity
<http://dbpedia.org/resource/Applause>. Do you see a place for this in
the Ontology for Media Resource?

I know that the document is in "Last Call" status, so my sincere
apologies if these questions should be inappropriate given the
ontology status. Also I might have overlooked the fact that what I
outline here is already possible, or explained elsewhere; thanks for a
pointer to resources in either case and sorry for the potential
confusion my comment might have caused then. Thanks.

container idea.
