HATEOAS Tumblog

Using an HTML5 microdata theme and featuring HATEOAS content. 

In this article, Jim Webber, Savas Parastatidis and Ian Robinson show how to drive an application's flow through the use of hypermedia in a RESTful application, using the well-known example from Gregor Hohpe's "Starbucks does not use Two-Phase-Commit" to illustrate how the Web's concepts can be used for integration purposes.

RESTful web services are one of our core design patterns. Fielding’s thesis identifies four major constraints that identify a RESTful architecture (statelessness, resource-orientation, uniform interface, hypermedia-driven application state). Many “RESTful” APIs only get 3 out of 4 of these; we’ve begun experimenting with using XHTML as a media type for our APIs, and this provides a lot of power in terms of scalability and loose coupling between client and server.
