Well, couldn't this be a case of "we're describing the same thing, BUT
we're using different descriptions" ?

It seems to me that skos:Concept is an *explicit* conceptualization of
some thing. With a history, purpose, etc in itself, separately from the
thing.

so by using owl:sameAs, we're saying that not only are the described
"things" the same, but we're also using the *same* conceptualization,
with the same history etc.

OTOH, it's certainly an interesting statement to say, well, we're
talking about the same thing (subjectIndicator) but we're using
different conceptualizations, etc.

So, in short, couldn't the answer be that we are really talking about
two resources - the thing and the conceptualization?
