> - remove ma-ont:Document (there is no Document class in the MA ontology)
> - replace ma-ont:locator of the collection by dc:format (as the use of MA locator causes the reasoner to infer that the instance is a MediaResource, which is in conflict of being a collection).

> Since this resource has a ma:locator property (Domain: ma:MediaResource) it will be inferred as an instance of class ma:MediaResource.
> Furthermore, ma:MediaResource and ma:Collection are disjoint classes and the ontology is consistent.

> -          In 3gp-Example-v4.rdf the xml:base directive should be removed in order to import the ma ontology correctly

> -          According to Pellet, the EBUCore example is inconsistent. Possible reason is that  at least one instance is a member of two disjoint classes (MediaResource and Collection).
