[protege-discussion] The relationship between a class and its subclass or superclass.

[Jonathan Carter]

I agree. That's the approach that I have taken and it works well.
Define your class hierarchy to describe what everything in your domain  
is. Then create a slot for the "part_of" relationship - this slot will  
be an "Instance" type and will contain the Instance of a class as per  
your requirements.

Hope this helps
