Karen,

I disagree that "language is the only option we have to create different
prefLabels." My LCSH vs. MESH illustration shows how skos:ConceptScheme
can be used as another dimension. If I had asserted owl:sameAs between
the two concepts, then we would agree that the two skos:prefLabels end
up colliding. Instead of using owl:sameAs, though, I used
skos:exactMatch. This is a weaker form of "equivalence" that preserves
the separate identities of the LCSH and MESH concepts while recognizing
"a high degree of confidence that two concepts can be used
interchangeably across a wide range of information retrieval
applications".

http://www.w3.org/TR/skos-reference/#L4858

I assume that MESH terms are jargon whereas LCSH terms are more suitable
for laymen. I think the definition of skos:exactMatch is a pretty good
match for this situation.

Jeff
