In UBIK, a MetaClass is used to define the appearance and behavior of a certain set of future content objects.
A MetaClass can, and actually has to, inherit from another MetaClass. This can be a built in UBIK System-MetaClass, which is typically the case when customizing starts in an "empty" data model. Of course, and more likely, it will be another MetaClass that was already created during customizing.
Derive new object
To generate a new metaclass just right-click on the sourceclass (e.g., the Baseclass) and choose Derive new object.
After this the class´s name can be changed in the bottom window ( Details )
