What do you mean by: "multiple  identical properties defined for a single
object" ?

We have that right now:

A r B.
C r B.
D r B.

We even have multiple identical properties for a single *subject* like:

A s B.
A s C.
A s D.

But if you want :

A q B.
A q B.
A q B.

Then, alas, that we don't have that.  Triples are unique within the
document, you end up with just one triple {A q B}.

Incidentally, why do you need any more than the second example {A s B. A s
C. A s D.}  to show that A is a member of three groups, and that some group
can have multiple members ?
