I assume they are referring to any of the many philosophical
"challenges" regarding identity which led people to assert that FOL was
broken and invent new systems.  The literature is replete with fun
little scenarios that can confuse FOL (or any other system for that

On the other hand, I agree that the semantics of FOL (and RDF) are
completely adequate for many useful cases, and we can make considerable
progress using the simple semantics and simple scenarios without having
to solve the age-old philosophical problems.
