An Analysis on SAWSDL and its Implementation Tools

Abstract

Recently, Semantic Annotations for WSDL (SAWSDL) standard emerged as a W3C recommendation to add semantics to WSDL components. SAWSDL annotates WSDL components with different semantics in order to automate Web service tasks, such as service discovery, composition, mediation, and invocation. In fact, certain service task requires a specific service semantic that semantically describes the service. As a result, several tools and techniques have emerged to allow users to get maximum advantage of semantic Web service by implementing SAWSDL. This paper analyzes SAWSDL standard. The relationships between SAWSDL and WSDL components were revealed. The direct relationships between SAWSDL components and service tasks through service semantics were investigated and reported. This paper also reviews some well-known tools that are used for SAWSDL implementation.
