Re: Elaborating on the Video use case

Dear all,

about MS IMM: http://blogs.msdn.com/imm/
  - implements the MPEG-21 Digital Item Declaration (DID) model using  
OWL/RDF and also uses MPEG-21 Digital Item Identification (DII)
  - they have sections to describe the audio, video, image, tape, and  
custom format
  - also include dublin core predicates
  - can also include domain specific predicates like IPTC, EXIF, XMP,  
SMPTE, etc.

More information about IMM was previously available on http://www.codeplex.com/IMM 
  but it seems it has been removed there

A document about IMM has been submitted to MPEG recently but I'm not  
sure I can disclose this here. In case you're interested, I can check  
this and I'll come back to you later.

Best regards,
  -Christian
