Hypermedia as the Engine of Application State (HATEOAS) is a component of the REST application architecture that distinguishes it from other network application architectures. With HATEOAS, a client interacts with a network application whose application servers provide information dynamically through hypermedia. A REST client needs little to no prior knowledge about how to interact with an application or server beyond a generic understanding of hypermedia. By contrast, clients and servers in CORBA interact through a fixed interface shared through documentation or an interface description language (IDL). The restrictions imposed by HATEOAS decouple client and server. This enables server functionality to evolve independently.
