Context-aware systems offer entirely new opportunities for application developers and for end users by gathering context information and adapting systems behavior accordingly. Several context models have been defined and various context-aware middleware has been developed in order to simplify the development of context-aware applications. Unfortunately, the development of an application by using these middleware products introduces several technical details in the application. These technical details are specific to a given middleware and reduce the possibility of reusing the application on other middleware. In this paper, we propose an MDD (Model Driven Development) approach that makes it possible to design context-aware applications independently of the platform. This approach is based on several phases that approach step by step the context platform and allow designers to automatically map their models to several platforms through the definition of automatic and modular transformations. To be able to apply this approach we define a new UML profile for context-aware applications, that we use to explore our approach.
