Protégé-Frames' user interface is organized along a set of tabs that each focus on a particular aspect of
ontology building.
The
Classes Tab is an ontology editor which you can use to
define classes and class hierarchy, slots and slot-value restrictions, relationships between classes
and properties of these relationships.
The
Forms Tab generates a default form for acquiring instances based
on the types of the slots that you have specified. You can then change the default form by rearranging the
fields on the screen, changing sizes, labels, and other properties for any slot.
The
Instances Tab is a knowledge-acquisition tool which you can use to
acquire instances of the classes defined in your ontology.
