Hi all,
   Seems that Raphael and Jacco have touched almost all of the points  
we would have made. That said, I will provide two additional points:

Additional Requirements for a Common Multimedia Ontology Framework

1) A common multimedia ontology framework should agree upon the  
terminology for linking multimedia object to resource defined in  
Semantic Web representation languages. Further, this agreed upon  
terminology should take into account the past approaches so that as  
much existing data can be repurposed with minimal syntactic and  
semantic transformations. For example, it is to the best of our  
knowledge that a majority of approaches current provide this linking  
via foaf:depicts, etc. (Note that this point has probably already  
been pointed out)

2) A common multimedia ontology framework should provide an agreed  
upon way to localize sub-regions of multimedia objects (e.g., sub- 
regions of images). Again this terminology should take into account  
past approaches. To the best of our knowledge, this has been  
accomplished using bounding box coordinates and/or SVG snippets  
describing such regions.


Cheers,
Chris
