The trend towards pervasive computing involves an increasing number of ubiquitous, connected devices. As a consequence, the heterogeneity of client capabilities and the number of methods for accessing information services on the Internet also increases. Nevertheless, consumers expect information services to be accessible from all of these devices in a similar fashion. They also expect that information services are aware of their current environment. Generally, this kind of information is called context. More precisely, in our work context constitutes information about consumers and their environment that may be used by Web services to provide consumers a customized and personalized behaviour. In this paper, we present a context framework that facilitates the development and deployment of context-aware adaptable Web services. We implemented the framework within our ServiceGlobe system, an open and distributed Web service platform.
