CubicWeb is a free and open-source semantic web application framework, licensed under the LGPL.

It has been an open free software project since October 2008, but the project began in 2000, and was initially developed by Logilab[5] for internal uses such as intranet, bug tracker and forge applications.

As of 2012, CubicWeb is being used in large-scale semantic web and linked open data applications,[6][7] and international corporations.

Interesting general purpose cubes include dbpedia and openlibrary.

The framework has been translated to English, French, Spanish and German (April 2011).
