Leveraging the Semantic Web with Linked Data

By Jerome Louvel, Thierry Templier, and Thierry Boileau
Hypermedia is not only about hypertext media types but also about hyperdata and, more importantly, about interoperability of data. This goal is shared by the Semantic Web, which was initiated by Tim Berners Lee. In this article, based on chapter 10 of Restlet in Action, authors introduce the Semantic Web and its relationship to REST via the new Linked Data trend, which is a great illustration of hyperdata. Then, they will introduce RDF, the core standard for semantic representations, and explain how to expose, consume, and browse linked data with Restlet.
