Ten companies, including IBM, Microsoft, Oracle, Sun, provide implementations The Web Services Interoperability Organization (WS-I) on Wednesday plans to release its WS-I Sample Application 1.0 documents, providing use cases for interoperable Web services.Being released at the XML Conference & Exposition 2003 event in Philadelphia, the documents consist of WS-I Supply Chain Use Cases 1.0, Usage Scenarios, Supply Chain Management Technical Architecture, and Sample Application 1.0 implementations developed by 10 vendor companies. The 10 companies include BEA Systems, Bowstreet, Corillian, IBM, Microsoft, Novell, Oracle, Quovadx, SAP, and Sun Microsystems.WS-I, with the documents, is looking to provide a simplified supply chain management scenario to demonstrate the features in the recently released WS-I Basic Profile 1.0 document for development of interoperable Web services. “The biggest part of it is the actual implementations” with companies implementing binary, sample applications to demonstrate interoperability, said Rob Cheng, product director of technology marketing at Oracle, a WS-I member company.While the documents focus on supply chain management, they are applicable to a variety of applications, Cheng said.Featured in WS-I are companies such as Microsoft, IBM, and Sun Microsystems, looking to promote the cause of interoperable integration via Web services technologies. WS-I Sample Application Profile 1.0 provides a configurable collection of Web services that use a supply chain scenario that models interactions between multiple retail storefronts, warehouses, and manufacturers, WS-I said. The Sample Application Technical Architecture featured in the documents implements several schema-naming conventions, SOAP message formats and styles, and WSDL design practices that conform to the Basic Profile. The Sample Application Usage Scenarios translate use cases into a set of technical requirements, defining general messaging patterns for Web services in structured interactions.The WS-I Sample Application 1.0 documents are downloadable off of http:// www.ws-i.org. Due next from WS-I are WS-I test tools and a security profile. Software DevelopmentTechnology Industry
