DESIGN PATTERN MATCHING

Since the beginning of software development re-usability has been an important aspect. Applying reusable elements the software does not have to be developed from scratch, proved solutions can shorten the software development life cycle and make applications safer. There are several forms of re-usability like function libraries, class libraries, design patterns, component technologies and enterprise templates, among which this article deals with design patterns. Our intention is to help developers to find the appropriate design patterns without having to study the tremendous amount of existing patterns. Therefore we complete the design pattern metamodel with some additional information about the pattern's purpose and responsibilities. This completion allows simplified search of patterns and query of design pattern properties.
