“I am getting frustrated by the number of people calling any HTTP-based interface a REST API. Today’s example is the SocialSite REST API. That is RPC. It screams RPC…” –Roy Fielding http://roy.gbiv.com/untangled/2008/rest-apis-must-be-hypertext-driven

–Roy Fielding http://roy.gbiv.com/untangled/2008/rest-apis-must-be-hypertext-driven “…What needs to be done to make the REST architectural style clear on the notion that hypertext is a constraint? In other words, if the engine of application state (and hence the API) is not being driven by hypertext, then it cannot be RESTful and cannot be a REST API. Period. Is there some broken manual somewhere that needs to be ﬁxed?”
