CubicWeb
CubicWeb is an 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.
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 (by default it provides a set of default views for each type of data).
A cube is a reusable component defining specific features. For example a cube forge allows one to create her own forge and the forge cube reuses the cubes comment, file, email, etc. Interesting general purpose cubes include dbpedia and openlibrary.
Features
- Semantic web: supports OWL/RDF
- Multi-source: supports RQL, SQL, LDAP, Subversion and Mercurial
- RQL: Relationship query language to ease data query
- Migration tool: fits into agile development
- View selection principle: the engine selects the best view to fit the content to display according to the context
- Cubes library: a wide range of cubes are available on the forge
