"DBpedia is a community effort to extract structured information from Wikipedia, and make it available for linking across the web in RDF, under an open licence. The database currently contains 1,600,000 concepts, including almost 60,000 people, 70,000 places, etc. These concepts are described by 91,000,000 RDF triples, using more than 8,000 properties.
DBpedia is made available via a SPARQL endpoint, with a Linked Data interface that Semantic Web browsers such as Tabulator can interact with, and via various RDF data dumps that developers can take and implement for themselves. The DBpedia data is licensed with the GNU Free Documentation License." (http://blogs.talis.com/nodalities/2007/05/www2007_linked_data_once_again.php)
