However, the maturity of soap can be provide

RESTful Web Services REST was presented in 2000 by Roy Fielding in his doctoral dissertation, one of the chief authors of the HTTP Specification version 1.0 and 1.1.The most important concept in REST is resources, which are identified by using a global ID (usually a URI). The client application uses the HTTP method (Get/post/put/delete) to manipulate the resource or resource set.
