Creative Commons CC0

mercredi 26 octobre 2011

La licence CC0 de Creative Commons répond au problème spécifique de la mise dans le domaine public d’une œuvre par son auteur, ou ses ayant-droits.

Cette licence s’adresse plus spécifiquement aux auteurs soumis au régime du copyright américain qui, depuis la fin des années 1970, s’applique automatiquement à toutes les œuvres présentées aux États-Unis.

La licence ci-dessous est précédée d’un texte explicatif, indispensable à lire pour en faire usage de manière appropriée.


About CC0 — “No Rights Reserved”

CC0 enables scientists, educators, artists and other creators and owners of copyright- or database-protected content to waive those interests in their works and thereby place them as completely as possible in the public domain, so that others may freely build upon, enhance and reuse the works for any purposes without restriction under copyright or database law.

In contrast to CC’s licenses that allow copyright holders to choose from a range of permissions while retaining their copyright, CC0 empowers yet another choice altogether – the choice to opt out of copyright and database protection, and the exclusive rights automatically granted to creators – the “no rights reserved” alternative to our licenses.

The Problem

Dedicating works to the public domain is difficult if not impossible for those wanting to contribute their works for public use before applicable copyright or database protection terms expire. Few if any jurisdictions have a process for doing so easily and reliably. Laws vary from jurisdiction to jurisdiction as to what rights are automatically granted and how and when they expire or may be voluntarily relinquished. More challenging yet, many legal systems effectively prohibit any attempt by these owners to surrender rights automatically conferred by law, particularly moral rights, even when the author wishing to do so is well informed and resolute about doing so and contributing their work to the public domain.

A Solution

CC0 helps solve this problem by giving creators a way to waive all their copyright and related rights in their works to the fullest extent allowed by law. CC0 is a universal instrument that is not adapted to the laws of any particular legal jurisdiction, similar to many open source software licenses. And while no tool, not even CC0, can guarantee a complete relinquishment of all copyright and database rights in every jurisdiction, we believe it provides the best and most complete alternative for contributing a work to the public domain given the many complex and diverse copyright and database systems around the world.

Using CC0

Unlike the Public Domain Mark, CC0 should not be used to mark works already free of known copyright and database restrictions and in the public domain throughout the world. However, it can be used to waive copyright and database rights to the extent you may have these rights in your work under the laws of at least one jurisdiction, even if your work is free of restrictions in others. Doing so clarifies the status of your work unambiguously worldwide and facilitates reuse.

You should only apply CC0 to your own work, unless you have the necessary rights to apply CC0 to another person’s work.

CC0

You are using a tool for freeing your own work of copyright restrictions around the world. You may use this tool even if your work is free of copyright in some jurisdictions, if you want to want to ensure it is free everywhere. Creative Commons does not recommend this tool for works that are already in the public domain worldwide, instead use the Public Domain Mark for such works.

Using CC0, you can waive all copyrights and related or neighboring rights that you have over your work, such as your moral rights (to the extent waivable), your publicity or privacy rights, rights you have protecting against unfair competition, and database rights and rights protecting the extraction, dissemination and reuse of data.

Keep in mind that you cannot waive rights to a work that you do not own unless you have permission from the owner. To avoid infringing third party rights, you should consult with your legal advisor if you are unsure whether you have all the rights you need to distribute the work.

Please note that this is not a registration process and Creative Commons does not store or save any of the information you enter. This tool guides you through the process of generating HTML with embedded metadata for marking your work as being available under CC0. Your work will not be associated with CC0 or made available under CC0 until you publish it marked as being so.
