[[Image:Kids sharing ice cream.jpg|right|thumb|250px|{{#ifexist:Template:Kids sharing ice cream.jpg/credit|{{Kids sharing ice cream.jpg/credit}}<br/>|}}Sharing, er, content.]] :''Also see [[CZ:License]].'' This document is meant to offer guidance to those who wish to reuse ''Citizendium'' content, such as Wikipedians. Wikipedia will soon be able to reproduce articles, parts of articles, and other content, that originated on the ''Citizendium.'' Wikipedia may right now use our versions of articles that began life on Wikipedia. Everyone else may use our content, as long as they reproduce it using our licenses. See [[CZ:License]] for "the official policy." This is a help/instructional page. The majority of ''Citizendium'' articles, including all of its original articles, are under the [[CZ:Creative_Commons_CC-by-sa_3.0|Creative Commons Attribution-Share Alike-3.0 Unported]] license (CC-by-sa). ''[[Citizendium]]'' additionally hosts a good number of articles under the [[CZ:GNU Free Documentation License|GNU Free Documentation License]] (GFDL) that began life at [[Wikipedia]]. The ''Citizendium'' chose the CC-by-sa for its original articles because we think it has important advantages over the GFDL, although the two provide very similar user rights. Also, we knew that the [[Creative Commons]], [[Free Software Foundation]], and [[Wikimedia Foundation]] had expressed intent to make the CC-by-sa and GFDL compatible in the near future. You '''must''' credit ''Citizendium'' [[CZ:Sharing_Content_with_Wikipedia#How_must_I_attribute_text_I_obtain_from_Citizendium.3F|in the manner stipulated below]]. == Which articles are currently portable to Wikipedia? == Citizendium has differing content policies than Wikipedia, but, after their recent switch to Creative Commons licensing, all Citizendium articles may be copied or merged to Wikipedia, if they fit Wikipedia's policies. == How to give ''Citizendium'' credit == If you use any ''Citizendium'' content elsewhere, you must attribute the ''Citizendium'' and link to http://www.citizendium.org/ as well as the relevant ''Citizendium'' article(s) from which you obtained text; also, include the date accessed. You must display this information ''within the article'' in the same point of font as the article's main text. Also, on wikis like Wikipedia, please make a note within the edit summary mentioning that you have uploaded material from the ''Citizendium'' on the day you do. :;''Example'' :{{cz |article=Félix d'Hérelle |url=http://en.citizendium.org/wiki/F%C3%A9lix_d%27H%C3%A9relle |accessdate=3 January 2007 }} The template {{tl|Cz-gfdl}} is an ideal tool for giving attribution to the ''Citizendium'' (it's been ported to Wikipedia, see [http://en.wikipedia.org/wiki/Template:Cz-gfdl here]). For materials under the CC-by-sa, the template {{Tl|Cz-cc-by-sa}} is another ideal tool, which displays similar to the above. The above also applies to derivative works of ''Citizendium'' text, such as translations. == Reusing articles with content from both ''Citizendium'' and Wikipedia == Third-party sites that reuse ''Citizendium'' CC-by-SA articles ''with'' Wikipedia-sourced content, and/or vice-versa, must credit ''both'' parties and link to the CC-by-SA. For information on attributing ''Citizendium'', see the preceding section. For information on attributing Wikipedia, see [http://en.wikipedia.org/wiki/Wikipedia:Copyrights Wikipedia:Copyrights.] == Reusing ''Citizendium'' images and other media == Although the ''Citizendium'' prefers media under terms compatible with Wikipedia's definition of "free," we accept ''all redistributable works'' (and still "less free", if needed) when media is otherwise unavailable or of inadequate quality.<ref>For an interesting way to compare CZ and Wikimedia projects in this way, see [http://commons.wikimedia.org/wiki/Commons_talk:Licensing/Archive_Ancient this old Wikimedia Commons discussion], where there is a debate between "Commons should accept all redistributable works", and "Commons should accept only 'free' works".</ref> See [[:Category:All media]] for an overview, but [[:Category:High-free media]] is where you will find media compatible with Wikimedia policies. Everything there should be straightaway importable into Wikimedia projects. When importing articles, you will of course need to check the licensing of each instance of media therein to see if you can import it into Wikipedia along with ''Citizendium'' text that is under the GFDL. Basically, if the licensing template of the ''Citizendium'' media instance has a <span style="color: rgb(0, 153, 0);">green background</span>, it ''should'' be good to go. For all other media, you will need to either try to find replacements or undertake your own permissions efforts or other evaluations. For Wikimedia-compatible media authored by ''Citizendium'' contributors, attribute it according to their stipulates and their chosen license. If there are no specific stipulations about attribution, the default is to attribute the media to the author by name, source it to the ''Citizendium'' and link to the specific page where the media resides, and copy over its creation date and licensing data. See also [[CZ:About Media Hosted at Citizendium|About Media Hosted at Citizendium]]. == What about Citizens wishing to transfer content from Wikipedia? == See [[CZ:How_to_convert_Wikipedia_articles_to_Citizendium_articles|How to convert Wikipedia articles to ''Citizendium'' articles]]. In general, in order to maintain a useful difference between the projects, the ''Citizendium'' discourages (but does not disallow!) uploading of Wikipedia articles. ==Links== * [[CZ:License]] * Larry Sanger's [http://www.citizendium.org/czlicense.html#Our%20license%20and%20license%20procedure essay] about why ''Citizendium'' chose the CC-by-sa for its original content. * [[CZ:Creative Commons CC-by-sa 3.0|Local copy: Creative_Commons_CC-by-sa_3.0]] * [[CZ:GNU Free Documentation License|Local copy: GNU Free Documentation License]] * [[GNU Free Documentation License|GNU Free Documentation License]] (an article about the license) ==Footnotes== {{reflist}} {{Content Policy}}
