RDF dump of all item labels, descriptions, and aliases in all languages. -> https://tools.wmflabs.org/wikidata-exports/rdf/exports/20160801/wikidata-terms.nt.gz RDF dump of all Wikidata property definitions, including datatypes, labels, descriptions, and aliases. -> https://tools.wmflabs.org/wikidata-exports/rdf/exports/20160801/wikidata-properties.nt.gz RDF dump of all statements, complete with references and qualifiers. -> https://tools.wmflabs.org/wikidata-exports/rdf/exports/20160801/wikidata-statements.nt.gz

Disclaimer:

The dumps differ substantially from the online version. The predicates, in the dumps, are assinged as entities then it may affect the results of a disambiguation process due to wikidata's topology.

For example:

From web, e.g., Barack Obama -> https://www.wikidata.org/wiki/Q76 contains this triple http://www.wikidata.org/entity/Q76 http://www.wikidata.org/prop/direct/P2283 http://www.wikidata.org/entity/Q7212330 .

However, from the dump, it is -> http://www.wikidata.org/entity/Q76 http://www.wikidata.org/entity/P2283v http://www.wikidata.org/entity/Q7212330
