CubicWeb


CubicWeb is a free and open-source semantic web application framework, licensed under the LGPL. It is written in Python.
It has been an open free software project since October 2008, but the project began in 2000, and was initially developed by Logilab 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, and international corporations.

Concepts

The framework is entirely driven by a data model. Once the data model is defined, one gets a functional web application and can further customize the views.
A cube is a reusable component defining specific features. For example, a cube allows one to create one's own forge and the forge cube reuses the cubes comment, file, email, etc. Interesting general purpose cubes include dbpedia and openlibrary.
The framework has been translated to English, French, Spanish and German.
