Dear all,

here is our mapping example from SMPTE  to MA ontology.
Any comments/reviews are welcome!

In the MA ontology the range of ma:isRelatedTo is ma:MediaResource. This would prevent me to relate a media resource to another document which isn' t a media resource.
For example, in the SMPTE document there is a reference to a so called production script which is a pdf document. Now it isn' t possible to refer to this document using the MA ontology. 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.

Furthermore there is a typo in section MPEG-7 (property aveargeBitRate) and I would change the mapping explaination for this property ("@average / 1024") to "@average x 1000". In MPEG-7 the measurement unit for bitrate is kbit/sec and the  multiplication factor to get bit/sec is 1000.

Thierry: Please can you upload all the files and update the review table again?. Please note that I have attached new MPEG-7 related documents as well, since I fixed some minor issues.
