Abstract
Context-aware systems acquire and use information from their environment to provide services to their clients. A meaningful use of this context requires understanding the activities taking place, which are frequently organized as workflows. Managing a workflow implies, having its activities and their connections defined: storing the state, recognizing the activities execution, evaluate the decision conditions, and making the necessary actions. In order to make workflows adaptable to an evolving environment, they have an abstract definition that is grounded to different runtime instances depending on the actual conditions. Thus, there is a mutual influence between context and workflows: the execution of workflows depends on the context and changes it. Our work addresses these needs with a contextaware architecture that supports the abstract definition and management of workflows. The architecture provides access and subscription mechanisms to the context information, and coordinates the information sharing among context-aware application components. The architecture is illustrated with a use case of path guidance.
