Using ontologies with UML class-based modeling: The TwoUse approach

UML class-based models and OWL ontologies constitute modeling approaches with different strength and weaknesses that make them appropriate for specifying different aspects of software systems. We propose an integrated use of both modeling approaches in a coherent framework – TwoUse. We present a framework involving different concrete syntaxes for developing integrated models and use an OCL-like approach for writing query operations. We illustrate TwoUse’s applicability with a case study and conclude that TwoUse achieves enhancements of nonfunctional software requirements like maintainability, reusability and extensibility.
