Dear all,

this is the new version with MediaFragment as a subclass of MediaResource, validated as OWL-DL.

Please check and feedback.

Best regards,

Jean-Pierre

Thanks Tobias, all,

There seem to be concensus. I'll work on a new version.

I was thinking about namedFragment. Although the MFWG makes this disctinction, I wonder if we need to in MAWG as we would have a property 'name' that be be documented or not.  Then the URI attributed to the fragment would use an MFWG format or another, accordingly.

I hope I'll find 5 minutes to do this today during my various meetings.

Regards,

Jean-Pierre

  Dear all,

given the definition of MF cited below, it makes sense to model MF like
that.

Best,

Tobias
