Hi all,

here are my comments concerning the latest verson of ma-ont:

Shouldn't the top level classes (Concept, Agent, Collection, Contributor, Location, MediaFragment, MediaResource) be disjoint or overlapping?
Since these classes are not overlapping, they should be marked as disjoint.

All subclasses of class Contributer - execpt class RatingProvider - have property restrictions (e.g. Actor actorIs some Person). 
Though an appropriate property - ratingProviderIs - is available.

Since now only some Contributor subclasses are described using property restrictions. Is there the intention to add property restrictions to the remaining classes as well?

The range definition for property duration is "MediaResource and not Image". 
An alternative way to describe this would be "AudioTrack or VideoTrack" (without negation) which could be easier to understand/interpret.  
The range definition for properties frameHeight, frameRate, frameWidth and samplingRate can be rephrased in a similar fashion.

Could you add inside the file, in a comment,  a version number (like
R12) and a date. It will ease when inserting the file into the Ont spec to track the version.
