Without knowing the definition of foaf:Person, it's difficult to
conclude that foaf:Person is not a property. However, even without
knowing the definition of a literal, it is easy to conclude that it is
not a suitable node to be used as a property, so in my opinion, it is
sensible to state that triples containing a literal as the predicate
have no meaning (even though I think they should be syntactically
allowed).
I think it would be perfectly possible to have a datatype mapping to
a value-space of properties. But I see no practical benefit with
this so I'd prefer not to support literal predicates syntactically.
I'd suggest, as a general principle, that one should ask: which is
easier, to allow them or to prohibit them? There are costs both ways.
Words like 'support' beg the question.
