I am not sure I understand everything here. But if I'm right, this discussion on (SKOS) labels illustrates the danger of using "values" for the stuff in Group 1, which we identified in our terminology chat in Cologne.
"Values" orient understanding the categories towards simple strings/labels, or reification of these (as SKOS-XL labels for instance). In a linked data environment, one should have a much more open approach to what can be used as a "reference" for producing descriptions (of books for example).

Trying to take an example we know well now :-)
http://viaf.org/viaf/24604287/#skos:Concept  may be in our Group 1
http://viaf.org/viaf/24604287/#foaf:Person may be in our Group 1
http://viaf.org/viaf/24604287/#rdaEnt:Person  may be in our Group 1
http://viaf.org/viaf/24604287/#Leonardo,+da+Vinci,+1452-1519 may be in our Group 1

There should be no assumption on the ontological nature of the "reference" resources. It really boils down to what a data publisher chooses to publish as reference set, and what a data consumer wishes to re-use.
