Modeler: Tutorial/Subtype and Generalisation

Classification and Qualification of subtypes

The classification and qualification of subtypes is identical to the classification and qualification of other fact type expressions. The classification and the qualification of the example below automatically generates a subtype structure. ('Employee with Driving Licence' as subtype of 'Employee').

CaseTalk marks fact types containing one role played by an nominalized fact type automatically as a subtype.
