The W3C has published a note on the Web Services Description Language. WSDL is an XML format for describing network services as a set of endpoints operating on messages containing either document-oriented or procedure-oriented information. WSDL is extensible to allow description of endpoints and their messages regardless of what message formats or network protocols are used to communicate, however, the only bindings described in the current document describe how to use WSDL in conjunction with SOAP 1.1, HTTP GET/POST, and MIME (which is enough for most web application developers at this point ;-). As communications protocols and message formats are standardized in the web community, it becomes increasingly possible and important to be able to describe the communications in some structured way. WSDL service definitions provide documentation for distributed systems and serve as a recipe for automating the details involved in applications communication. I've started toying with .NET. Microsoft is doing a lot of interesting things, WSDL included.
