Web Service Choreography Interface (WSCI)

Web Service Choreography Interface (WSCI) is an XML-based language initially proposed as a standard for describing web services choreography. WSCI provides a way to describe the interactions between web services in a choreography, including the sequence of messages exchanged and the conditions under which they are exchanged.

WSCI was designed to be used with other web services standards, such as Web Services Description Language (WSDL) and Simple Object Access Protocol (SOAP), to provide a complete solution for describing and implementing web services. It was intended to provide a high-level description of the choreography, which automated tools could use to generate the lower-level implementation details.

However, WSCI was never widely adopted as a standard, and it has been largely superseded by other choreography languages, such as WS Choreography Description Language (WS-CDL). One reason for this was the language's complexity, which made it difficult to use and understand. Additionally, there were concerns about WSCI's compatibility with other web services standards and its lack of support for newer technologies, such as Representational State Transfer (REST) and JavaScript Object Notation (JSON).

Despite these limitations, WSCI played an important role in developing web services choreography, and it contributed to developing other standards in this area. It remains an interesting case study in the evolution of web services standards and the challenges involved in creating a cohesive and interoperable set of technologies.
