To whom it may concern,

My name is SungKu, who's working as a graduate research assistant at UIUC and 
working on Jena and SADL(which is based on Jena).

I'd like to perform reasoning based on the number of object related with a 
subject through certain kind of property.
(e.g. Polygon and (hasSide exactly 4 Thing) is a Square)

I know counting requires closed world assumption but I want to know if there 
are some built-in primitive which can perform as if the ontology is based on 
closed world assumption.
(e.g. "hasNumberOfPropertyValues" of SWRL built-in)

Is there any Jena rule built-in primitives or other feature that can perform 
such reasoning?

Regards,

Kang, SungKu
