WSCI to Coordinate Web Services
WSCI, an XML-based language codeveloped by Sun, BEA, Intalio and SAP AG, promises to improve Web services collaboration.BEA Systems Inc., Intalio Inc., SAP AG, and Sun Microsystems Inc. have announced the publication of the XML-based Web Service Choreography Interface (WSCI) specification for application to application collaboration. The new specification, released Wednesday and made available for public comment at the companies Web sites, provides a foundation for delivering on the claims of Web services to deliver automated, application to application collaboration, said Simon Phipps, chief technology evangelist at Sun.
WSCI describes the flow of messages exchanged by a Web service in a particular process and the collective message exchange among interacting Web services, providing a global view of a complex process involving multiple Web services, the companies said. Todays service description languages are adequate for simple information retrieval, such as a stock quote, but they do not provide the rich behavioral detail that describes the role the service plays as part of a larger, more comprehensive collaboration, officials of the companies said. The companies also said WSCI bridges the gap between business process management and Web services by describing how a Web service can be used as part of a larger, more complex business process, Phipps said. These business processes may reside entirely within the confines of a single company, or span across multiple organizations, he said.
