Hmm...not really. My point is that I want to develop a system that loads the
constraints and rejects 'broken' updates. This is just like RDBMSs keep data
from becoming 'incorrect' (according to the constraints). I want to avoid
having to develop extra checking code.

Basically, I want business rules (aka constraints) expressed as RDF.

I could of course develop my own vocabulary for this, but something
standardized would be better.

Thanks anyway,

Jan
