# Web services interoperability (WS-I)

WS-I is an organization designed to promote Web service interoperability across platforms, operating systems, and programming languages.

For more information on WS-I, refer to their Web site: http://www.ws-i.org/. This site contains resources such as an overview of Web services interoperability, usage scenarios, and specifications.

WS-I Basic Profile is a outline of requirements to which WSDL and Web service protocol (SOAP/HTTP) traffic must comply in order to claim WS-I conformance. The Web services WS-I validation tools currently support WS-I Simple SOAP Binding Profile 1.0 (WS-I SSBP) and the WS-I Attachments Profile 1.0 (WS-I AP). To view the specifications, refer to the WS-I Web site, and under Resources select Documentation.

Depending on the type of Web service being created, you may or may not want your Web service to comply with the WS-I Profiles. The default level of compliance is to generate a warning if a non WS-I SSBP complaint Web service option is selected and to ignore any non WS-I AP compliant selections. You can set the level of WS-I compliance at the workspace or project level. The Web services wizards, the WebSphere® run-time environments, the WSDL editor, and other Web services tools provided support and encourage the development of WS-I compliance services.
