Abstract

Web service composition lets developers create applications on top of serviceoriented computing’s native description, discovery, and communication capabilities. Such applications are rapidly deployable and offer developers reuse possibilities and users seamless access to a variety of complex services. There are many existing approaches to service composition,ranging from abstract methods to those aiming to be industry standards. The authors describe four key issues for Web service composition. In service-oriented computing (SOC), developers use services as fundamental elements in their application-development processes. Services are platform- and network-independent operations that clients or other services invoke. To operate in an SOC environment, services must overtly define their properties in a standard, machine-readable format. SOC thus offers three native capabilities: description, discovery, and communication. 1 Web services are a typical SOC example: developers implement SOC native capabilities
