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”.
Dear Robert,

Yes, here we should actually talk about three things: The holding of the right, the content of the right, and the concept of the right. E30 is intended to be the content of the right, which is relatively trivial if it is just an instance of unspecified copyright, but not if it is an individual contract. If the holding of the right can be merged with the content or not, is to be discussed. See my previous message.

best,

martin

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!

Rob
