data: Freebase, Wikidata, DBpedia (from Wikipedia)

Freebase (database) - Wikipedia

Data Dumps  |  Freebase API (Deprecated)  |  Google Developers

1.9B RDF triples, 31 GB

Freebase Easy - Dataset Download

3.3 GB

Freebase Easy (Cities in Europe)

Both projects publish RDF data about entities. The source of the data is very different: whereas DBpedia extracts the data from the infoboxes, Wikidata will collect data entered through its interfaces. 

Data in Wikidata will also be annotated with its provenance: it does not simply state the population of Germany, but it also requires a source to be given for the data. The two data repositories will co-exist.

DBpedia (from "DB" for "database") is a project aiming to extract structured content from the information created in the Wikipedia project.

The Developers page lists the file as 22 GB gzip compressed and 250 GB uncompressed, although a recent download exceeds this file size (a May 2016 download amounted to >30 GB compressed and >400 GB uncompressed).
