Model-Driven Development of Context-Aware Services

Abstract. In this paper, we define a model-driven design trajectory for contextaware services consisting of three levels of models with different degrees of ion and platform independence. The models at the highest level of platform independence describe the behaviour of a context-aware service and its environment from an integrated perspective. The models at the intermediate scribe abstract components, which realize the context-aware service in a service-oriented abstract platform. At the lowest level, the realization of a context-aware service is described in terms of specific target technologies, such as Web Services, BPEL and Parlay technologies. Our approach allows service designers to concentrate their efforts on the services they intend to create and offer, by facilitating the handling of context information and automating design steps through model transformation. In addition, our approach enables the reuse of platform-independent models for different target platforms.
