Right, "the sender asserts that the payload is a representation of the resource identified by the Content-Location field-value". So, the sender (DBpedia) asserts that http://dbpedia.org/resource/Barack_Obama is a REPRESENTATION of the resource http://dbpedia.org/resource/Barack_Obama, but the recipient has no way to know that the resource http://dbpedia.org/resource/Barack_Obama is a real-world entity… One really nice way to say that http://dbpedia.org/resource/Barack_Obama is real-world entity is for RDF returned by http://dbpedia.org/resource/Barack_Obama to say so :) Regards, Dave -- http://about.me/david_wood > > Best, > Richard
