CategoryRelationStructure

Generalization is Identifiable.

Superclass hierarchy

Definition

Relation structure of categories within a collection

Examples

The category of student might be described as having sub-types of primary school student and high school student.

Explanatory notes

The CategoryRelationStructure employs a set of CategoryRelations to describe the relationship among concepts. Each CategoryRelation is a one to many description of connections between categories. Together they might commonly describe relationships as complex as a hierarchy. This is a kind of a ConceptStructure restricted to categories (which are concepts). Allows for the specification of complex relationships among categories.
