I have 2 related problems of expressing things in RDF graphs

1. I want to talk about a set of things and not its members. For example the
class of "Groups of people".
Do I just have to create a name and a property called set of
(Anonymity set)(is a set of)(Nyms)
Or is this going to cause problems?

2. I want to express a mathematical relationship between the cardinality of
2 sets.
(x) (is cardinality of) (Anonymity set)
(y) (is cardinality of) (Identity set)
(linkability) (is value of) (x/y)

Please help!
