Group formed by Microsoft, IBM, and Oracle says it has concluded charter to document best practices for Web services The Web Services Interoperability Organization (WS-I), formed nearly a decade ago by vendors such as Microsoft, IBM, and Oracle, is going out of business.In a statement released on Wednesday, WS-I said it had concluded its charter to document best practices for Web services interoperability across multiple platforms, operating systems, and programming languages. WS-I documents released include Basic Profile 1.2 and 2.0 and Reliable Secure Profile 1.0.[ Also on InfoWorld: WS-I focused on SOAP Web services. XML co-inventer Tim Bray has called the SOAP stack a failure. | XML pioneer Jean Paoli dismissed the REST vs. SOAP-based WS-* Web services duel. ] “By publishing the final three profiles, WS-I marks the completion of its work. Stewardship over WS-I’s assets, operations and mission will transition to OASIS (Organization for the Advancement of Structured Information Standards),” WS-I said in a statement.“All of these profiles are supported by the shipping version of .Net Framework 4.0. Through our collective profile development and testing efforts, Microsoft and other WS-I members have delivered a better customer experience based on Web services interoperability,” said Microsoft’s Paul Cotton, partner group manager, in a statement released by WS-I. The organization was founded in 2002.WS-I had become less relevant in recent years with developments such as the industry’s embrace of alternative REST Web services, analyst Ron Schmelzer, managing partner of ZapThink, said. “The need for the WS-I is not as great as it was.” Companies acquiring each other also has diminished issues of interoperability, such as Sun Microsystems and BEA Systems becoming part of Oracle, said Schmelzer. SOAP was fairly complicated, which spurred formation of WS-I, he said.This article, “WS-I declares ‘mission accomplished’,” was originally published at InfoWorld.com.
