Creative Commons is a comprehensive license suitable for copyleft distribution of creative works. The Creative Commons License was developed in 2002 under the guidance of Lawrence Lessig. He is the Roy L. Furman Professor of Law at Harvard Law School and the former director of the Edmond J. Safra Center for Ethics at Harvard University. Creative Commons covers a wide range of works, including books, movies, plays, music, articles, photographs, website and blogs.
The Creative Commons License is based on four pillars: Attribution, Share-Alike, Non-Commercial, No-Derivatives. Let us describe each of them:
Attribution (BY): The user may copy, distribute, display or modify the work by giving attribution to the creator.
Share-Alike (SA): Users must distribute the modified work using the license used for original work. Attribution to the original creator is necessary.
Non-commercial (NC): Users can copy, distribute, display, modify and reproduce the work only for the non-commercial uses. Attribution to the original creator is necessary. No-Derivatives (ND): Users are only allowed to copy, distribute, and display the work. Not allowed to modify the work. Attribution to the original creator is necessary.
A variety of licenses can be generated by mixing and matching Creative Commons basic terms. Signs for each license can be generated to display along with the work. Based on a combination of the four conditions mentioned above, six major Creative Commons licenses can be generated.
- Name — Short-form — Conditions
- Attribution — CC BY — This license lets others distribute, remix, tweak, and build upon your work, even commercially, as long as they credit you for the original creation.
- Attribution ShareAlike — CC BY-SA — This license lets others remix, tweak, and build upon your work even for commercial purposes, as long as they credit you and license their new creations under the identical terms.
- Attribution-No Derivatives — CC BY-ND — This license lets others reuse the work for any purpose, including commercial; however, it cannot be shared with others in adapted form, and credit must be provided to you.
- Attribution-NonCommercial — CC BY-NC — This license lets others remix, tweak, and build upon your work non-commercially, and although their new works must also acknowledge you and be non-commercial, they don’t have to license their derivative works on the same terms.
- Attribution-NonCommercial-ShareAlike — CC BY-NC-SA — This license lets others remix, tweak, and build upon your work non-commercially, as long as they credit you and license their new creations under the identical terms.
- Attribution-NonCommercial-NoDerivatives — CC BY-NC-ND — This license is the most restrictive of our six main licenses, only allowing others to download your works and share them with others as long as they credit you, but they cannot change them in any way or use them commercially
