I probably don't understand your objection. The data does matter,
and I'm assuming that it will be in rough accordance with the
ontology. The query referred to below was
?occurrence rdf:type dwc:occurrence .
?occurrence dwc:ofIndividual [individual] .
for some specific value of [individual].
If I read your example correctly, there's an occurrence of an individual
named "wolfpack". So if I'm querying for occurrences of "wolfpack", then
your occurrence would be returned.
But maybe the point of your example isn't that the individual is named
wolfpack, but that the individual *is* a wolfpack, and the rdf is bad. In
this case, yes, problems will arise.
One question that your example raises (and is maybe related to what you
have in mind?) is: Supposes we allow Individuals/BiologicalEntities to include
wolf packs. How would we query for occurrences of wolf packs? One proposal
on the table last Fall was to include some sort of scoping property for
the Individual class, e.g. scope="individualOrganism", or
scope="Population". We could also define individualOrganism and
Population to be subClasses of biologicalEntity.
Please let me know if I've missed your point entirely.
