Based on the upcoming O'Reilly book "RESTful Web APIs" by Leonard Richardson and Mike Amundsen, this 1/2 day workshop covers the basics of Fielding's REST style, HTTP standards, and common practices for APIs for Web. Key topics such as how how use hypermedia to increase API flexibility and how application profiles can improve API interoperability are also covered. In addition, a wide range of existing message formats and semantic vocabularies are reviewed along with a procedure for selecting and applying these existing standards to your own implementations. Other subjects will be covered such as caching, versioning, and supporting RESTful APIs on protocols other an HTTP.Throughout the workshop, attendees will be able to apply step-by-step guidance on how to create their own RESTful Web API and share these designs with the group at the end of the session.
