The Concept Modeler can specify equivalence between two classes, import equivalent classes from OWL, and export equivalent classes to OWL. Class equivalence expresses a generalization relationship stereotyped as «Equivalent Class». The Concept Modeler will draw this with a double-headed arrow.
Two equivalent classes in Concept Modeler.
From the figure above, the equivalence class relationship, identified by the «Equivalent Class» stereotype, defines that the two classes are semantically equivalent to each other.
For more information on how to create equivalent classes, see Create Equivalent Classes.
