This document provides an overview of Freebase, a socially managed semantic database. Freebase allows users to extend its data model by adding new types, properties, and data. It provides a graph data structure and query interface to enable flexible relationships between data. Freebase publishes its data as RDF to support portability and enable many applications to utilize the data in unexpected ways.
