Web application description language (WADL)

This article describes the Web Application Description Language (WADL). An increasing number of Web-based enterprises (Google, Yahoo, Amazon, Flickr - to name but a few) are developing HTTP-based applications that provide access to their internal data using XML. Typically these applications are described using a combination of textual protocol descriptions combined with XML schema-based data format descriptions; WADL is designed to provide a machine processable protocol description format for use with such HTTP-based Web applications, especially those using XML.
