Presented at JAX London 2013 Hypermedia or HATEOAS APIs get a lot of air cover but there aren't many of them in the wild. This session will summarize the challenges that exist when building hypermedia REST API’s and explain why it’s worth it. We’ll take a comparative look at various different approaches for using hypermedia in a typical REST API, before taking a closer look at an approach that automatically generates links from a semantically rich API definition.
