Abstract: Based on correctly understanding the essence of Web Services Modeling Framework (WSMF), the practical application of WSMF should be summarized to decomposing and coding the WSMF elements. The WSMF is essentially an entity containing four toplevel elements called the Web services, goal, mediator, Ontology, and their interactive relations. The elements and their relations of WSMF are derived from the viewpoints of reusability, decoupling, and semantic mediation service, and are refined and expanded into a hierarchical system of bottomlevel elements according as Web Services Modeling Ontology (WSMO). The WSMF bottomlevel elements are formalized in description by using Web Services Modeling Language (WSML), and then transformed into XML code. An actual Web service is given to illustrate the methods and the process of decomposing and coding the WSMF toplevel elements.
