CZ:Reusing Citizendium 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 Creative Commons Attribution-Share Alike-3.0 Unported license (CC-by-sa). Citizendium additionally hosts a good number of articles under the 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 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
- This article incorporates text from the Citizendium article "Félix d'Hérelle" (retrieved on 3 January 2007), which has been licensed under the GNU Free Documentation License.
The template {{Cz-gfdl}} is an ideal tool for giving attribution to the Citizendium (it's been ported to Wikipedia, see here).
For materials under the CC-by-sa, the template {{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 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.[1] 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 green background, 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.

What about Citizens wishing to transfer content from Wikipedia?
See 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.
