Session: Hypermedia APIs

Wednesday, 13:10 - 14:00
Track: Web development

RESTful web services are one of our core design patterns. Roy 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 (instead of the more traditional JSON or Atom types), and this provides a lot of power in terms of scalability and loose coupling between client and server. I can go over these concepts and perhaps even do some coding-on-the-fly to demonstrate some of these client and server concepts.
