If we want to keep RDF but drop something, there's only named nodes we
can drop without loosing expressiveness. We would have to introduce an
inverse functional property pointing to a URI-Literal. This would also
make the owl:sameAs statement obsolete (it would just be one b-nodes
with multiple name-properties). Another advantage would be that there
are less arbitrary choices to take when describing a world with things
with multiple names, currently you can arbitrarily decide which
properties to associate with which of the same resources (the concept of
having multiple things being the same, seems counter-intuitive to me
anyway).
