Thanks, this is much more productive.

I've made the mappings at
http://dev.w3.org/2008/video/mediaann/mediaont-1.0/mediaont-1.0.html#ogg-table
and in the RDF files which should have helped you. It's the point of
this spec. But let me help you.

please make this:

TRACK NAME: audio_1 --> identifier
TRACK NAME: video_1 --> identifier
TITLE --> title  (RDF-tested:Yes)
URL: DougExample.ogv --> locator
ORGANIZATION: Web Directions South --> creator
CONTACT: silviapfeiffer1@gmail.com --> creator
DATE: --> date  (RDF-tested:Yes)
LOCATION: --> location  (RDF-tested:Yes)
COPYRIGHT: --> copyright  (RDF-tested:Yes)
Media Fragment URIs:
DougExample.ogv#track=audio_1, DougExample.ogv#track=video_1 --> fragments
DougExample.ogv#chapter=introduction, DougExample.ogv#chapter=twitter
--> named fragments
Video-Width: 352, Video-Height: 576--> frameSize
video/theora, audio/vorbis --> compression
55.488 --> duration
video/ogg -> format
48000 HZ --> samplingRate
25 fps --> frameRate
285.210 kbps --> bitRate
2 --> numTracks


In fact, I just notice that the CONTACT field is not in
http://dev.w3.org/2008/video/mediaann/mediaont-1.0/mediaont-1.0.html#ogg-table
, so could be added there under "creator" next to "ORGANIZATION".

It's the same as above, not none. See
http://dev.w3.org/2008/video/mediaann/mediaont-1.0/mediaont-1.0.html#ogg-cont-table
.


> For WebM
>
> Title:    --> title  (RDF-tested:Yes)
> Duration: --> duration  (RDF-tested:Yes)
> Language: --> language  (RDF-tested:Yes)


please make this:

TrackUID: 1 and 2 --> identifier
Track number: 1 --> identifier
Name: video-1, audio-1 --> identifier
Title: W3C and Twitter --> title
Language: en --> language
Locator: DougExample.webm --> locator
Duration: 55.500s (00:00:55.500) --> duration
Media Fragment URIs:
DougExample.webm#track=audio-1, DougExample.webm#track=video-1 --> fragments
DougExample.webm#chapter=introduction,
DougExample.webm#chapter=twitter --> named fragments
Pixel width: 352, Pixel height: 576 --> frameSize
video/vp8, audio/vorbis --> compression
Duration: 55.500s --> duration
video/webm -> format
48000 HZ --> samplingRate
25 fps --> frameRate
75.443 kbps,  285.210 kbps --> bitRate
2 --> numTracks

Hope this helps.

Yes, I think whoever the Protege expert is should check this for all
of the files.
