Web service technologies are becoming increasingly important for integrating systems and services. There is much activity and interest around standardization and usage of web service technologies. Contemporary web services are described in the Web Service Description Language (WSDL). However, WSDL documents can be difficult to understand for service developers.

During the development of Web services and their deployment to a specific target system, organizations need to evaluate if the Web service implementation and the hardware can meet the Quality of Service attributes specified in a Service Level Agreement. One important aspect are performance-related attributes, such as response time, throughput or scalability of the Web service. Typically tests w...

This paper presents a mechanism that facilitates and enhances the use of independently administered remote network servers in the presence of server interface heterogeneity. The mechanism is designed under the client-service model, which extends the client-server model with an abstraction of service to decouple abstract server capabilities from concrete server interface specifics such as server...

We are developing a language, Web Service Offerings Language (WSOL), for the formal specification of various constraints, management statements, and classes of service for Web Services. WSOL is an XML (Extensible Markup Language) notation compatible with WSDL (Web Services Description Language). A service offering in WSOL is a formal description of one class of service of a Web Service. It cont...
