Re: SMPTE to MA mapping example

Martin, Pierre Antoine,

I have uploaded all the SMPTE and MPEG-7 files and update the review table.
http://www.w3.org/2008/WebVideo/Annotations/wiki/Format_mapping_review

Also I did change the  property aveargeBitRate for MPEG-7
http://dev.w3.org/2008/video/mediaann/mediaont-1.0/mediaont-1.0.html#mpeg-table

Pierre Antoine:

Do you agree to change the MA ontology the range of ma:isRelatedTo 
currently  a MediaResource ?

Best,

thierry

Therefore I suggest to remove this domain spec form a:isRelatedTo. Moreover in section 5.1.2 of the Ontology for Media Resources 1.0 document, property relation is not restricted to media resources.
