Web Services Interoperability
The Web Services Interoperability Organization (WS-I) was an industry consortium created in 2002 and chartered to promote interoperability amongst the stack of web services specifications. WS-I did not define standards for web services; rather, it created guidelines and tests for interoperability. In July 2010, WS-I joined the OASIS, standardization consortium as a member section. It operated until December 2017. The WS-I standards were then maintained by relevant technical committees within OASIS.
It was governed by a board of directors consisting of the founding members (IBM, Microsoft, BEA Systems, SAP, Oracle, Fujitsu, Hewlett-Packard, and Intel) and two elected members (Sun Microsystems and webMethods). After it joined OASIS, other organizations have joined the WS-I technical committee including CA Technologies, JumpSoft and Booz Allen Hamilton.
The organization's deliverables included profiles, sample applications that demonstrate the profiles' use, and test tools to help determine profile conformance.
