Design Patterns, Formal Specification, DPSL, UML
Design patterns 1 can be regarded as an approach to encapsulating good design practices and to reusing them. However, most of design patterns are specified using informal text and examples. To use all of the benefits of patterns, formal specification and tool support are indispensable. This paper examines the concepts and constituents of design patterns, and proposes a DPSL (Design Pattern Specification Language) that is able to represent them. To apply patterns in the design modeling of UML, we developed a prototype tool that supports DPSL in the UML diagram. This prototype shows software engineers the tool's support possibilities and the usability of patterns.
