Hi Robert
I may be splitting hairs here but my reading of your example wordings are not quite what is meant.
So for your Martin example my wording would be "The particular instance of copyright, on this particular thing, that is held by Martin" so it is not the act of holding that is represented by the class but the thing that is held. I hope that makes it clearer.
The query pattern looks correct to me.
CC licenses would, to my understanding, be types of E30 Right and so E30-P2-E55 would be correct.

Subject: [Crm-sig] Rights model

Dear all,

Given the current model, I believe that E30 Right is an instance of the holding of a Right, rather than the concept of the Right itself?  For example, E30 is not “Copyright” or “Apache 2.0” or “Ownership” … it is “The holding of copyright of an object by Martin”, “the use of Apache 2.0 for some code by Rob”, or “Ownership of a house by Emma”.

If this is not intended to be the case, can someone provide an example in RDF (your serialization preference is fine) that demonstrates two different people holding two different rights over the same object?

Given that … we are expected to then use P2_has_type to refer to the sort of Right, and thus queries should look for: ?object P104_is_subject_to ?right . ?right P2_has_type <actual_right> .
If so, how would one refer to the Creative Commons licenses? Still with P2?

Many thanks!
