RDF for a Freebase topic

Question

I am using the python library rdflib to query Freebase for topics.

I found that the data returned by Freebase for topics are not complete. For instance, when I query:

http://rdf.freebase.com/rdf/en.barack_obama

The result does not contain data about place_of_birth although I can verify that the data exists when I use MQL to query for that property.

My question is: Can I rely on a query to the RDF service to return all the rdf triples for a given topic?

If not, is there a way to ensure I get all the triples?

Answer 1

Unfortunately the answer is no. Certain topics link to thousands of other topics in Freebase and our APIs would timeout if we didn't impose a limit on the number of triples returned. We're going to be releasing a complete RDF dump of Freebase in the near future. That will be the best way to get all the RDF data.
