Re: [poe] Vocab clarifications

This looks fine!

I just have one doubt: I had not realized that this pattern was for constraints that applies to groups (collections) of resources. I thought it could be a bid wider, as in the Web Annotation pattern for SpecialResource.
If source applies to collection, then its meaning may be compared to a part-of relationship, like dc:isPartOf. I mean, the new resource (sub-collection) is a part of the original one.
So maybe you could re-use dc:isPartOf directly.
But that may have unintended consequence though, as it probably doesn't carry a meaning as precise as what you seek for collection constraints (I mean, "source" points to the set use as base for extracting the group of interest, it's not any super-set). So a more conservative stance could be to add a sub-property axiom between odrl:source and dc:isPartOf.
I won't push it very hard, because it is clearly not crucial to the model. But it may bring some useful interoperability later on. And for now, clarify the intended semantics of odrl:source.
