AGAP : un Atelier de Gestion et d'Application de Patrons

New applications development environments have been developed together with pattern oriented approaches. These tools address two kinds of actors: patterns engineer who specifies patterns systems and applications engineer who uses these systems to specify information systems. Most of existing tools are made for applications engineers; they offer few functionalities allowing definition and organization of patterns systems. This paper presents AGAP, a development environment for defining and using patterns, which distinguishes patterns formalisms and patterns systems. It allows patterns engineer to define several patterns systems by using the same formalism or by reusing fields of existing formalisms in order to facilitate the engineering of information systems and increase the level of reuse.
