“Representational State Transfer (REST) goes with the grain of basic web services to develop a resource-oriented architecture (ROA). It is an alternative to SOAP and Web service description language (WSDL). A hybrid version using remote procedure calls (RPC) is implemented on API sites such as del.icio.us and flickr, Amazon E-commerce, and Yahoo! search, and through utilities including Atom Publishing Protocol (APP), Amazon Simple Storage Service (S3), and Google GData. The results are more addressable, cacheable, stateless and well-connected since URIs and links are exposed and HTTP is exploited. Examples are shown using AJAX, Javascript object notation (JSON) and a variety of frameworks. Authors’ sites: Crummy.com for Richardson, interwingly.net for Ruby.”
