I think that is your view and the view you have codified as the
authoritative definition that I can look up at that URI, but there is
nothing preventing me from making any assertion I like and working
with that in my own environment. If it's useful to me to say
foaf:Person a rdf:Property then I can just do that. However, I
shouldn't expect that assertion to interoperate with other people's
views of the world.
