Semantic Discovery and Composition of Web Services for RFID Applications in Border Control1

Recognition is growing for the need of richer semantic specifications of Web Services to support automated service selection and invocation, automated or semi-automated service composition, as well as more comprehensive approaches to service monitoring. In this paper, we combine [12] an approach for composing Web Services on the semantic web and [10] using OWL-S for explicitly describing the semantics to Web Services. We propose an OWL-S based approach for the automatic composition of Semantic Web Services and present a technique to generate composite services from high-level declarative descriptions. We discuss its implementation for the shipment monitoring application, an open, multimodal end-to-end tracking and tracing system in the Border Control domain based on Semantic Web Services as part of the SAP Auto-ID infrastructure.
