The availability of the web has made it possible to provide new life to legacy systems as Web services components within a service-oriented architecture. Web Services are self-contained, modular applications that can be described, published, located, and invoked over a network, generally, the World Wide Web. The service-oriented architecture describes three roles: service provider, service requester and service broker; and three basic operations: publish, find and bind. A network component can play any or all of these roles. Web services focus on the integration and infrastructure complexities of B2B by leveraging the benefits of web service technologies, internet standards and common infrastructures. This working session will discuss approaches for addressing these issues. Based on the results of the session, a working model will be developed that lists current approaches, their strengths and weaknesses, as well as current open issues.
