Abstract :
Context-aware applications assist users´ everyday tasks by adapting their behavior based on context information obtained from instrumented environments. Context is any relevant information describing entities in a user-computer interaction (e.g. user location). The design and implementation of high-quality context management software is an area of active research. We have described elsewhere the context kernel, a Web service that manages context information on behalf of applications. In this paper, we present a case study of how the context kernel has been used to integrate a suite of e-learning applications. We show how the Web services approach allowed applications to seamlessly exchange context on the Web through a uniform context representation schema. We also present the lessons we learned from integrating e-learning applications via Web services.
