Some thoughs:

Pragmatically speaking if there is one thing that "linked data" buys
us is new URIs for the same thing others might be talking about, but
specifically minted within "one's context", that is the name space of
the site who's hosting the RDF

so http://dbpedia.org/resource/Berlin is really not "berlin" in
general but obviously "something that they have in their DB that has
label "berlin" and bla bla

then there is http://geonames/123456 that might also be berlin.  If
there is an agreement by the dbpedia guys that that entity is
equivalent for DBPEDIA PURPOSES to their entities then the dbpedia
people put a "sameAs" between the two. So "sameAs" on the web of
linked data is always a "directed sameAs"

This pragmatic interpretation should be "we people at dbpedia believe
that it might be useful for you as a robot to also go collect
information from this other source as we find it generally compatible
with the information we provide here"

given this interpretation of "linked data URIs" (something i
previously called URI/URLs and i still dont find a better term for it)
then i believe its perfectly valid to state things about the URI
itself, since they always must be interpreted within the context where
they were taken.

i know, OWL doesnt account for this, that is, it will not make
distinctions between "context only valid statements" and not.. but i
see no alternative to deal with this at preprocessing level, e.g. when
you crawler picks up linked data information, you should look for said
context onyl valid statments before you smush all together with the
sameAs
