Freebase Data Dumps
Freebase provides full data dumps of all the current facts and assertions in our system. You've always been able to use our developer API to access this information, and we've recently made it easy to export tabular data about a single Freebase type through our website, but now for the first time you can grab everything in one convenient package.
Freebase data dumps are complete, general-purpose extracts of the Freebase data in a variety of formats. We will be releasing a fresh data dump every three months.
Data Dumps
Two formats are currently available:
-
TSV - a tab-separated file for each type in Freebase, suitable for loading into spreadsheets or database software. Each line in these files represents an instance of a Freebase type, the columns represent the available properties for the type. You may download the full set, or browse Freebase domains and types to find specific data sets.
The July 2008 full download is approximately 389 Mbytes compressed in the Bzip2 format.
The July 2008 browseable set contains 1260 TSV files in 142 domains.
Link Export - A full dump of Freebase assertions in a simple utf8 text format. This is a complete "low level" dump of data which is suitable for post processing into RDF or XML datasets.
The format of the link export is a series of lines, one assertion per line. The lines are tab separated quadruples, <source>, <property>, <destination>, <value> An assertion is a statement of fact about the <source> object.
In any assertion, either the <destination> or <value> or both <destination> and <value> are present.
A sample of this output is available.
The July 2008 Link Export contains approximately 116MM assertions and is approximately 824 Mbytes compressed in the Bzip2 format (updated July 19, 2008).
