General information on generalizations

The aim of the concept of specializations and generalizations is to allow the subdivision of entity types into subtypes. There are a number of different categories of specialization. The specialization category determines the criterion for the specialization. Specializations are linked to the source entity type (=generalization) via the specialization category.

See also Specializations/generalizations.
