Re: looking for a social schema

Dear Ghalem,

since such a property would be in a conflict with the open world 
assumption underlying the semantic web (you simply cannot tell "how many 
things of type X are there" in an open world), I suppose there is no 
serious schema which has such a property.

Best,
Heiko.
