Without having checked what you meant with InstanceConcept: I did not 
mean global URI and local URI, I meant local _identifier_.

So the concept has a global URI (as usual), and also different 
properties attached to it that record the identifier used in different 

	skos:prefLabel "Christianity"
	ex:edition1ID "abc123"
	ex:edition2ID "xyz321"

This situation also occurs in the cultural heritage portals I'm involved 
in; we provide artworks with a URI, but also record the local ID that 
the museums give to the artworks.
