MQL

MQL is an abbreviation for Metaweb Query Language.

MQL, usually pronounced “mickle,” is the programmatic interface to Freebase, or the API. That is, it’s the way applications—including those you may write--get information into and back out of the data store at the heart of Freebase. The current implementation (MQL-J) uses JSON (JavaScript Object Notation) syntax, making it ideal for JavaScript and python based clients. A future version of MQL (MQL-X) will support XML syntax.

You’re encouraged to write your own application using the Freebase data in whatever way you think is useful! For guidance and inspiration, check out the MQL manual and a bunch of webs apps that were built with Freebase data.
