Freebase RDF Interface

Welcome to the Freebase RDF service.

This service generates views of Freebase Topics following the principles of Linked Data. You can obtain an RDF representation of a Topic by sending a simple GET request to http://rdf.freebase.com/ns/thetopicid, where the "thetopicid" is a Freebase identifier with the slashes replaced by dots. For instance to see "/en/blade_runner" represented in RDF request http://rdf.freebase.com/ns/en.blade_runner

The /ns end-point will perform content negotiation, redirecting your client to the HTML view of the Topic if HTML is prefered (as it is in standard browsers) or redirecting you to http://rdf.freebase.com/rdf to obtain an RDF representation in N3, RDF/XML or Turtle depending on the preferences expressed in your clients HTTP Accept header.

This example shows how the Freebase identifier for S. Meenakshi Ammal (http://rdf.freebase.com/ns/en.s_meenakshi_ammal) can be used in RDFa to unambiguously identify who reviewed a restaurant:

<span xmlns:v="http://rdf.data-vocabulary.org/" typeof="v:Review">
   <span rel="v:itemReviewed">
       <span about="http://komalavilas.com" property="v:name" typeof="v:Restaurant">Komala Vilas</span>
   </span>
   <span rel="v:reviewer">
       <span about="http://rdf.freebase.com/ns/en.s_meenakshi_ammal"
       property="v:name">Meenakshi Ammal</span>
   </span>
   <span property="v:rating" >3.7</span>
   <span property="v:date">1st April 2005</span>
   <span property="v:summary">Best south Indian vegetarian food in the bay area</span>
</span>
