Extensibility and Modularity for Model Driven Engineering Environments

Model Driven Engineering has shown the feasibility to generate tools (editors, analyzers ...) from models and for a domain. Unfortunately these generated tools are much focused while a large application spans different domains and different activities; currently these tools do not support concurrent engineering, and incomplete life cycle support. In a similar way we developed a technology capable of generating a complete Computer Aided Domain Specific Environment (CADSE) from a set of model and metamodels describing the specific domain and the environment behavior. Our technology solves the above two problems, allowing defining a number of CADSE addressing specific activities, as extensions and adaptation of a core CADSE; and relying on workspaces. CADSEs workspaces are model driven; they contain tools, models and usual artifacts (code, documents...); they support different activities by switching from an activity to another one, and concurrent engineering is supported through import/commit applied to models, metamodels and artifacts.
