Web Services Interoperability Organization (WS-I) is an open industry body formed in 2002 to promote the adoption of Web services and interoperability among different Web services implementations. Its role is to integrate existing standards rather than create new specifications. WS-I publishes profiles that describe in detail which specifications a Web service should adhere to and offer guidance in their proper usage. The goal is to provide a set of rules for integrating different service implementations with a minimum number of features that impede compatibility.
