Hi,

...a follow-up on my last question:

Is there an RDF vocabulary for expressing integrity constraints on RDF-modeled
data?

An example would be: "The salary of employees may not be greater than X if
their age is less than y".

This implies the question if there is an RDF vocabulary for expressing
expressions of property values and if XML schema datatypes can have
operators defined on them.

Thanks for any help.

Jan

Aside: Since the relational data model can do all of the above (and in theory
for arbitrary data types (aka classes)) it would be pretty nice if RDF could,
too.
