The Inheritance View is available if a selected resource is a Class. The view will be emptied when you switch from a Class to another type of resource, such as a Property or an Instance. As this is not one of the default views, you may need to go to Window > Show View to open it.
The Inheritance view shows all superclasses of a class - including restrictions - in a reversed hierarchy. In the example below (showing the inheritance of the Capital class), City is the direct superclass, City has the parents UrbanArea and Destination. City also has been defined to be a subclass of a restriction on the hasAccommodation property.
