[protege-discussion] Intersections in protégé

[Samson Tu]

You need to describe your problem more precisely. In your diagram, are 
the circles classes or instances? Is the "is" relation "subclass" or 
"instance-of" relations? In your diagram, which are possible combinations?

With best regard,
Samson Tu
