This would be possible to say. The problem is that there would be no
way on earth that anyone could come to an agreement as to what kind

is undecidable.
What is the difference between the above and
foaf:knows a rdf:Property .

Well we can dereference foaf:knows to find out what it means. This is
the canonical way to find it's meaning, and is the initial procedure we
should use to arbitrate between competing understandings of its meaning.
