Re: Next iteration of the RDF ontology

Dear Jean-Pierre and all,

    I took a look to the ontology you sent on 15th November, and I have 
a pair of comments (maybe you have already discussed about them, sorry 
if this is the case).

- With respect to the Track class and its subclasses (AudioTrack, 
Captioning, VideoTrack), I would suggest to complete the comments for 
the subclasses, because as it is know is difficult to understand the 
meaning of them (for a newcomer). In this context I have a pair of 
doubts: is it AudioTrack the same as Segment? is it VideoTrack the same 
as Frame? is it Captioning the same as Subtitle? If so, could you 
consider to include these labels as synonyms of the existing classes?

- In the case of the relation called "isFragmentOf" (domain: 
MediaFragment; range: MediaResource), I was wondering if it would not be 
better to extend/modified the current modelling in order to avoid 
possible inconsistences (such as "an image having as a fragment a video 
track and an audio track").

Thank you very much in advance. Best Regards,

       Mari Carmen.
