DBpedia is now interlinked with Freebase. Links to OpenCyc updated.

Freebase is an open-license database which provides data about million of things from various domains. Freebase has recently released an Linked Data interface to their content (See release note). As there is a big overlap between DBpedia and Freebase, we have added 2.4 million RDF links to DBpedia pointing at the corresponding things in Freebase. These links can be used to smush and fuse data about a thing from DBpedia and Freebase. For instance, you can use the Marbles Linked Data browser to view data about the Lord of the Rings from Freebase and DBpedia smushed together.

 We have also updated the the RDF links to OpenCyc, which allow you to use DBpedia instance data together with conceptual knowledge of OpenCyc.
