Yes, I know that borrowing terms is allowed. Indeed, it gets used every day.

The thing is that we're talking about maybe cleaning RDF up a little.
(emphasis on the "maybe" - though that's starting to look more
likely). In this case, it makes sense to me that a term for equality
would make it's way into RDFS, simply because there are a lot of use
cases where people are sticking to just that namespace, with the
single exception of owl:sameAs. Also from an aesthetics point of view,
equality is such a common concept that I'm surprised it wasn't already
lower in the stack.

Nothing in RDF *needs* to be changed. But if it does get updated, then
I think that it would be nice to clean things a little while all the
new features get added (such as named graphs).

Regards,
Paul Gearon
