Web Services Interoperability Technologies (WSIT)

Web Services Interoperability Technologies (WSIT) is an open-source software platform developed by Java Web service engineers and Microsoft’s Windows Communication Foundation (WCF) (also known as Indigo) to ensure atomic transactions, security and reliable messaging interoperability.

WSIT was previously known as Project Tango, and was developed as part of Java's open source Glassfish Community.

Web Services Interoperability Technologies enterprise features are categorized as follows:

• Metadata: Components include Web Service Description Language (WSDL), WS-Metadata Exchange and WS-Policy. WSDL is built into the Java application programming interface (API) for XML-based Web Services (JAX-WS).
• Security: WS-Security provides confidentiality and message content integrity, while WS-Metadata Exchange provides service metadata to consumers. WS-Security components are the WS-Security policy, WS-Trust and WS-Secure Conversation.
• Messaging: Components include Simple Object Access Protocol (SOAP) integrated in JAX-WS to support message transmission optimization of SOAP's wire format. WS-Addressing enables multiple transports.
• Quality of Service (QoS): Components are WS-Reliable Messaging and WS-Coord.
