Ways to restrict the properties a class may have?

Hi,

I know about the various ways to constrain individual properties, but
I seem to be unable to find out if there is a standard way of restricting
the set of properties instances of a given class may 'have'.
(Like relational tables form classes by grouping attributes)

Is there an RDF vocabulary for this purpose?

Hmm....what about owl:minCardinality (and owl:maxCardinality)? Does
a missing cardinality of a property for a class imply the cardinality of zero?
Or would relying on that be too application specific?

Thanks for any help on this.

Jan
