communiqué de presse

Paris, June 26, 2006


Coinciding with "Paris Capitale du Libre", a day of conferences focusing on free software, the CEA, CNRS and INRIA have announced the issue of the CeCILL-B and CeCILL-C free software licenses. The initiative comes in response to the growing demand for free and open source software and highlights the interest of these Europe's leading research organisations in this collaborative approach to development.

The CeCILL license (Ce as for CEA, C as for CNRS, I as for INRIA and LL as for the French term for free software) was issued in July 2004 to adapt to French law – in accordance with European law – the principles for the use and distribution of free software set out in the GNU GPL license, the most widely used American license.

CeCILL-B and CeCILL-C have been created to meet different needs in terms of development  and use and to promote wide distribution of software products.

CeCILL-B is based on the model of the BSD license and its variants (Apache, X11 or W3C licenses, etc.). The "author" allows its software to be reused with no restrictions other than an obligation to quote sources (documentation, software interface, web site).

CeCILL-C is ideal for the distribution of libraries and software components in general. Anyone distributing an application which includes components under the CeCILL-C license must mention this fact and make any changes to the source code of these components available to the community.

CeCILL, CeCILL-B and CeCILL-C now make up the first coherent family of free software licenses under European law. The three licenses all offer the same legal advantages and share the main body of their text with clauses clearly guaranteeing their compatibility. They have been designed as a new and original instrument, guaranteeing legal efficiency and covering a broad spectrum of requirements. They are intended for free software developers, companies and organisations wishing to use this type of software with the maximum legal security.

About INRIA

INRIA (French National Institute for Research in Computer Science and Control) is devoted to research in the field of Information and Communication Science and Technology (ICST). INRIA employs a workforce of 3,600 people, including 2,800 scientists (INRIA and partner organizations), in six research units based in seven major geographic regions*. INRIA has an annual budget of 160 million euros excluding VAT, 20% of which comes from its own research contracts and licences.
INRIA develops numerous partnerships with the industry and participates in technological transfers and the creation of companies (80) in the field of ICST, particularly through its subsidiary INRIA-Transfert, promoter of four start-up funds.
These international partnerships involve receiving and recruiting foreign students, as well as important exchanges between researchers. Priority is given to geographic areas with strong economic potential such as Europe, Asia and North America, whilst maintaining a low level of activity with South America, Africa and the Middle East.
* Aquitaine, Bretagne, Lorraine, Ile-de-France, Nord Pas de Calais, Provence Alpes Côte d'Azur et Rhône-Alpes.
