Specifying Fractal and GCM Components with UML

UML 2 has introduced new diagrams for expressing hierarchical structures and their assembly, and has brought some new features to the behaviour-oriented diagrams (activities and state machines), that help modelling component systems. However, UML leaves many semantic decisions opened, and various emerging component frameworks also have features that cannot be directly expressed using UML 2 concepts. In this paper we present an approach for modelling two different component frameworks using UML 2 diagrams. First we define a mapping between the Fractal component model and UML 2 diagrams, and we describe CTTool, that allows to edit and model-check diagrams for Fractal components. Then we propose an extension of this work for the Grid Component Model, that is an extension of Fractal providing asynchronous, collective, and autonomic features for distributed component systems.
