Many of the licenses, notably all the original licenses, grant certain "baseline rights", such as the right to distribute the copyrighted work without changes, at no charge. Some of the newer licenses do not grant these rights.
Creative Commons licenses are currently available in 43 different jurisdictions worldwide, with more than nineteen others under development. Licenses for jurisdictions outside of the United States are under the purview of Creative Commons International.
Original licenses Edit
The original set of licenses all grant the "baseline rights". The details of each of these licenses depends on the version, and comprises a selection of four conditions:
- Attribution (by): Licensees may copy, distribute, display and perform the work and make derivative works based on it only if they give the author or licensor the credits in the manner specified by these.
- Noncommercial or NonCommercial (nc): Licensees may copy, distribute, display, and perform the work and make derivative works based on it only for noncommercial purposes.
- No Derivative Works or NoDerivs (nd): Licensees may copy, distribute, display and perform only verbatim copies of the work, not derivative works based on it.
- ShareAlike (sa): Licensees may distribute derivative works only under a license identical to the license that governs the original work. (See also copyleft.)
Mixing and matching these conditions produces sixteen possible combinations, of which eleven are valid Creative Commons licenses. Of the five invalid combinations, four include both the "nd" and "sa" clauses, which are mutually exclusive; and one includes none of the clauses. The five of the eleven valid licenses that lack the Attribution element have been phased out because 98% of licensors requested Attribution, but are still available for viewing on the website. There are thus six regularly used licenses:
- Attribution alone (by)
- Attribution + Noncommercial (by-nc)
- Attribution + NoDerivs (by-nd)
- Attribution + ShareAlike (by-sa)
- Attribution + Noncommercial + NoDerivs (by-nc-nd)
- Attribution + Noncommercial + ShareAlike (by-nc-sa)
A number of additional licenses have been introduced, which are more specialized:
- Sampling licenses, with two options:
- Sampling Plus - parts of the work can be copied and modified for any purpose other than advertising, and the entire work can be copied for noncommercial purposes
- Noncommercial Sampling Plus - the whole work or parts of the work can be copied and modified for noncommercial purposes
Besides licenses, Creative Commons also offers an easy way to release material into the public domain through the Public Domain Dedication, as well as Founder's Copyright, through which the work is released into the public domain after 14 or 28 years.
Retired licenses Edit
Due to either disuse or criticism, a number of previously offered Creative Commons licenses has since been retired, and are no longer recommended for new works. The retired licenses include all licenses lacking the Attribution element, as well as two licenses not allowing non-commercial copying:
- Sampling – parts of the work can be used for any purpose other than advertising, but the whole work can't be copied or modified
- DevNations – a Developing Nations license, which only applies to countries deemed by the World Bank as a "non-high-income economy". Full copyright restrictions apply to people in other countries.
The maintainers of Debian GNU/Linux, a Linux distribution known for its adherence to software freedom, do not believe that even the Creative Commons Attribution License, the least restrictive of the licenses, adheres to the Debian Free Software Guidelines due to the license's anti-DRM provisions (which could restrict private redistribution to some extent) and its requirement in section 4a that downstream users remove an author's credit upon request from the author. As the other licenses are identical to the Creative Commons Attribution License with further restrictions, Debian considers them non-free for the same reasons. There have been efforts to remove these problems in the new version 3.0 licenses, so they can be compatible with the DFSG. As of July 2007, it remains to be seen if version 3 of the Attribution and Attribution-ShareAlike licenses will be approved by Debian.
Free Software Foundation Edit
The Free Software Foundation accepts the CC-BY v2.0 and the CC-BY-SA v2.0 Creative Commons licenses as being free, though not recommending it for software, but explains that it is vital to avoid the problem with the overly vague statement "I use a Creative Commons license" , without noting the actual license. Richard Stallman has criticised particular licenses for not allowing the freedom to make verbatim copies of the work for noncommercial purposes, and said that he no longer supported Creative Commons as an organisation, as the licenses no longer all had this freedom in common. Creative Commons have since retired these licenses, and no longer recommends their use.
Freelance photographer Dan Heller claimed that the licenses are created in such a way that if the work was licensed in CC by someone altering the copyright notice of the original work, then the licensee will be held liable to copyright infringement damages, even though the downstream licensees were fooled by original perpetrators, which increases legal risk for CC licensee. Furthermore, copyright holder of the registered copyrighted works can game the CC system by withdrawing CC licenses and erase evidence of the issuing such licenses, then sue people who use the copyrighted works. One could argue however, that this would be a limitation of the media upon which the content is stored, not the license itself.
In 2007, Virgin Mobile launched a bus stop ad campaign promoting their cellphone text messaging service using the work of amateur photographers who uploaded their work to Flickr using a Creative Commons-by (Attribution) license. Users licensing their images this way freed their work for use by any other entity, as long as the original creator was attributed credit, without any other compensation required. Virgin upheld this single restriction by printing a URL leading to the photographer's Flickr page on each of their ads. However, one picture, depicting 15 year-old Alison Chang at a fund-raising carwash for her church, caused some controversy when she sued Virgin Mobile. The photo was taken by Alison's church youth counselor, Justin Ho-Wee Wong, who uploaded the image to Flickr under the Creative Commons license. Template:Cquote
