In the pervasive and mobile computing environment, workflow and context information are closely linked, workflow management system have to interact with a variety of sensors. Therefore, the design and development context-aware workflow applications become complex and difficult to migrate to other platforms. In order to simplify the development of context-aware workflow applications and enhance its portability, a new context-aware workflow framework is proposed in this paper. This framework introduced into the context-aware middleware. Context-aware middleware shielding the various bottom sensors work details for the application and make the workflow applications focus on using high-level context, so as to realize the intelligent workflow management. This framework also introduced into ontology based modeling language for context-aware workflow. Case study shows that our proposed modeling language has good adaptability, and can be used to easily describe any sophisticated context-aware workflows.
