The Role of Pattern Languages in the Instantiation of Object-Oriented Frameworks

Abstract

In this paper we propose the use of pattern languages to guide an object-oriented framework instantiation. Both the framework and the pattern language refer to the same domain, and the framework must have been constructed based on the pattern language. The framework instantiation here proposed is done in several steps, all of them supported by the pattern language. This makes it easier for the developer to instantiate applications, as the knowledge about the pattern language is used during the instantiation process. The proposed approach is illustrated with the example of a framework we have built based on a pattern language for an information systems' domain.
