[protege-discussion] Problems with disjoint classes

[Julian Vincent]

I want to describe (for instance) a an organ such as a skeleton made of tissues such as bone, tendon and cartilage.   But all the tissues are disjoint.  So the skeleton is not passed by the Reasoner and is assigned to the 'Nothing' class.  
An inverse of this, producing the same problem, is to take a number of objects, such as an exoskeleton (an organ), a microtubule (an organelle) and a bone (a tissue) and say that they all provide support.  But organ, organelle and tissue are disjoint.

What's the way around this?
