Lisensi Creative Commons
Creative Commons licenses are copyright licenses issued on December 16, 2002 by Creative Commons, an American not-for-profit corporation founded in 2001. Many of these licenses, especially the original license, grant "fundamental rights", such as to distribute copyrighted works without modification, at no cost. Some newer licenses do not grant these rights. Creative Commons licenses are currently available in 34 different jurisdictions around the world, with nine more under development.
All original licenses grant "fundamental rights". The details of each of these licenses are version dependent, and consist of a choice of four conditions:
Attribution (attribution, A, “BY”): Allows others to copy, distribute, display, and create derivative works based on a work only if that person gives credit to the creator or licensor in the form of attribution or inclusion of the title of the work, name of the author, source , and the creative commons license used or in the manner specified in the license.
Noncommercial (noncommercial, NK, “NC”): Allows others to copy, distribute, display, and create derivative works based on a work for non-commercial purposes only.
No derivative works, noderivs, TKT, “ND”): Allows others to copy, distribute, and display only verbatim copies of a work, not derivative works based on the work.
ShareAlike (share-alike, BS, “SA”): Allows others to distribute a derivative work only under a license identical to the license granted to the original work (see also copyleft). Merging and matching these conditions results in six twelve possible combinations, of which eleven are valid Creative Commons licenses. Of the five invalid combinations, four of them include both “nd” and “sa” clauses which are mutually exclusive; and the other does not include a single clause, which means relinquishing the rights of a work in the public domain. Five of the eleven valid licenses that do not include the Attribution element are (almost) deprecated because 98% of licensors request Attribution, but are still viewable on the website. There are six commonly used licenses:
Six CC . general licenses
Attribution only (BY): Creators (including licensors) are credited
Attribution-NonCommercial (BY-NC): The author is credited and for non-commercial purposes only.
Attribution-No Derivatives (BY-ND): The author is credited and only the verbatim (exact match) work is given.
Attribution-ShareAlike (BY-SA): The author is credited and the work may be downgraded under an identical license.
Attribution-NonCommercial-No Derivatives (BY-NC-ND): The author is credited and the work is verbatim for non-commercial purposes only.
Attribution-NonCommercial-ShareAlike (BY-NC-SA): The author is credited and may be downgraded under an identical license for non-commercial purposes only.
