The Horizon architecture supports exposing a RESTful interface for use by programmatic clients. This session will review REST principles, compare REST to WS-* web services, discuss ROA and SOA, and review Horizon's framework support for REST.

This session will examine code to show how REST is supported and configured within Horizon. We'll look at a RESTful controller that exposes a 'resource' using various 'representations' (Grails default XML and JSON, and a custom representation that complies with an XML Schema).
