[Protege]OWL- What is a slot?

Question

I have been trying to understand what is a "slot" in OWL Language. From what i understand it's the object and the data properties of a class. Can someone please explain what is a slot, and how do i add it in Protege? Thanks in advance.

Answer 1

The slot concept that you refer to in Protege is as implemented in Protege up to version 3.x (version 4.0 and newer do not really have the same frame/slot architecture but are OWL oriented; the concept of slot does not really fit in OWL).

An explanation of what a frame and a slot are is available in the Javadoc for the old Protege code: http://protege.stanford.edu/protege/3.4/docs/api/core/edu/stanford/smi/protege/model/Frame.html

This should give you enough reference material to investigate further (I'm no expert on frames so I can't help much without more precise questions).
