Creative Commons is a non-profit organization that provides free legal resources. It is known for its copyright licenses, which help protect works and simplify the management of intellectual property rights by offering different types of licenses. These licenses are classified according to their degree of flexibility, ranging from the most permissive to the most restrictive.

Among the Creative Commons licenses, the first is the CC0 license, which allows a work to be placed directly into the public domain. Next, the CC BY (Attribution) license allows distribution, modification, and adaptation, including for commercial purposes, provided the author is credited. The CC BY-SA (Attribution-ShareAlike) license offers similar possibilities while adding the requirement to share derivative works under the same conditions.

Other licenses, such as CC BY-ND (Attribution-NoDerivatives) and CC BY-NC (Attribution-NonCommercial), impose additional restrictions. Finally, the CC BY-NC-SA (Attribution-NonCommercial-ShareAlike) and CC BY-NC-ND (Attribution-NonCommercial-NoDerivatives) licenses offer various combinations of restrictions to suit creators’ needs.

In short, Creative Commons offers a range of flexible licenses that allow authors to define the terms of use for their works while promoting sharing and creativity.
