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>This service will display content in Firefox if you use the Tabulator extension.
