    • Freebase has information about approximately 20 million Topics or Entities at the time of writing. Each one has a unique Id, which can help distinguish multiple entities which have similar names, such as Henry Ford the industrialist vs Henry Ford the footballer.

      Most of our topics are associated with one or more types (such as people, places, books, films, etc) and may have additional properties like "date of birth" for a person or latitude and longitude for a location. These types and properties and related concepts are called Schema.

      Anyone can contribute data to Freebase, and you can also build your own schema in a Base if Freebase does not yet have schema for a subject you're interested in.

    • Freebase is a graph database. This means that instead of using tables and keys found in conventional database to define data structures, Freebase defines its data structure as a set of nodes and a set of links that establish relationships between the nodes. Because its data structure is non-hierarchical, Freebase can model much more complex relationships between individual elements than a conventional database, and is open for users to enter new objects and relationships into the underlying graph.
