摘要：Today, service in oriented applications need to be enhanced to sense and react to user��s context in order to provide a better user experience. To meet this requirement, Context-Aware Services (CAS) have emerged as an underling design and development paradigm for the development of context-aware applications. The fundamental challenges for such applications development are context management and service adaptation to the user��s context. To cope with such requirements, we provide in this paper a context, context provider and CAS specifications and metamodels, and a tool to enhance a core service, in service oriented applications, to be context-aware. This enhancement is satisfied across a Aspect based pattern which, inspired by the Aspect Paradigm (AP) concepts, considers the service��s adaptations as aspects.
