From English WikiNoah
This agreement only covers text appearing on Wikinoah not otherwise marked with copyright or trademark information. Any copyright, trademark or licensing agreement marked on a specific page supersedes this agreement.
The license Wikinoah uses grants free access to our content in the same sense as free software is licensed freely. This principle is known as copyleft. That is to say, Wikinoah content can be copied, modified, and redistributed so long as the new version grants the same freedoms to others and acknowledges the authors of the Wikinoah article used (a direct link back to the article satisfies our author credit requirement). Wikinoah articles therefore will remain free forever and can be used by anybody subject to certain restrictions, most of which serve to ensure that freedom.
To fulfill the above goals, the text contained in Wikinoah is licensed to the public under the GNU Free Documentation License (GFDL). The full text of this license is at English Wikinoah:Text of the GNU Free Documentation License. This text should not be changed due to legal reasons.
- Permission is granted to copy, distribute and/or modify this document under the terms of the GNU Free Documentation License, Version 1.2 or any later version published by the Free Software Foundation; with no Invariant Sections, with no Front-Cover Texts, and with no Back-Cover Texts.
- A copy of the license is included in the section entitled "GNU Free Documentation License".
- Content on Wikinoah is covered by disclaimers.
The English text of the GFDL is the only legally binding document; what follows is our interpretation of the GFDL: the rights and obligations of users and contributors.
Users' rights and obligations
If you want to use Wikinoah materials in your own books/articles/web sites or other publications, you can do so, but you have to follow the GFDL. If you are simply duplicating the Wikinoah article, you must follow section two of the GFDL on verbatim copying, as discussed at English Wikinoah:Verbatim copying.
If you create a derivative version by changing or adding content, this entails the following:
- your materials in turn have to be licensed under GFDL,
- you must acknowledge the authorship of the article (section 4B), and
- you must provide access to the "transparent copy" of the material (section 4J). (The "transparent copy" of a Wikinoah article is any of a number of formats available from us, including the wiki text, the html web pages, xml feed, etc.)
You may be able to partially fulfill the latter two obligations by providing a conspicuous direct link back to the Wikinoah article hosted on this website. You also need to provide access to a transparent copy of the new text. However, please note that the Wikimedia Foundation makes no guarantee to retain authorship information and a transparent copy of articles. Therefore, you are encouraged to provide this authorship information and a transparent copy with your derived works.
An example notice, for an article that uses the Wikinoah article Metasyntactic variable might read as follows:
- This article is licensed under the <a href="http://www.gnu.org/copyleft/fdl.html">GNU Free Documentation License</a>. It uses material from the <a href="http://en.wikinoah.org/wiki/Metasyntactic_variable">Wikinoah article "Metasyntactic variable"</a>.
("Metasyntactic variable" and the Wikinoah URL must of course be substituted accordingly.)
Alternatively you can distribute your copy of "Metasyntactic variable" along with a copy of the GFDL (as explained in the text) and list at least five (or all if fewer than five) principal authors on the title page (or top of the document). The external Page History Stats tool can help you identify the principal authors.
Fair use materials and special requirements
All original Wikinoah text is distributed under the GFDL. Occasionally, Wikinoah articles may include images, sounds, or text quotes used under the U.S. Copyright law "fair use" doctrine. It is preferred that these be obtained under the most free (libre) license (such as the GFDL or public domain) practical. In cases where no such images/sounds are currently available, then fair use images are acceptable (until such time as free images become available).
In Wikinoah, such "fair use" material should be identified as from an external source (on the image description page, or history page, as appropriate). This also leads to possible restrictions on the use, outside of Wikinoah, of such "fair use" content retrieved from Wikinoah: this "fair use" content does not fall under the GFDL license as such, but under the "fair use" (or similar/different) regulations in the country where the media are retrieved.
Wikinoah does use some text under licenses that are compatible with the GFDL but may require additional terms that we do not require for original Wikinoah text (such as including Invariant Sections, Front-Cover Texts, or Back-Cover Texts). When wanting to contribute such texts that include Invariant Sections or Cover Texts to Wikinoah, see Introducing invariant sections or cover texts in Wikinoah below.
Images and photographs, like written works, are subject to copyright. Someone owns them unless they have been explicitly placed in the public domain. Images on the internet need to be licensed directly from the copyright holder or someone able to license on their behalf. In some cases, fair use guidelines may allow a photograph to be used.
Image description pages can be tagged with a special tag to indicate the legal status of the images, as described at English Wikinoah:Image copyright tags. It is currently unclear what should happen in cases where the same image has been uploaded more than once with different respective copyright statements.
U.S. government photographs
Works produced by civilian and military employees of the United States federal government in the scope of their employment are public domain by statute. However, note that, despite popular misconception, the U.S. Federal Government can own copyrights that are assigned to it by others (for example, works created by contractors). Be careful, however: not all images on .mil and .gov websites are public domain. Among other reasons, the site may be using commercial stock photography owned by others. It may be useful to check the privacy and security notice of the website, but only with an email to the webmaster can you be confident that an image is in the public domain. It should also be noted that governments outside the U.S. often do claim copyright over works produced by their employees (for example, Crown Copyright in the United Kingdom). Also, most state and local governments in the United States do not place their work into the public domain and do in fact own the copyright to their work. Please be careful to check ownership information before copying.
UK Crown Copyright
- Crown copyright protection in published material lasts for fifty years from the end of the year in which the material was first published. Therefore [for example] material published [fifty-one years ago], and any Crown copyright material published before that date, would now be out of copyright, and may be freely reproduced throughout the world. 
Contributors' rights and obligations
If you contribute material to Wikinoah, you thereby license it to the public under the GFDL (with no invariant sections, front-cover texts, or back-cover texts). In order to contribute, you therefore must be in a position to grant this license, which means that either
- you own the copyright to the material, for instance because you produced it yourself, or
- you acquired the material from a source that allows the licensing under GFDL, for instance because the material is in the public domain or is itself published under GFDL.
In the first case, you retain copyright to your materials. You can later republish and relicense them in any way you like. However, you can never retract the GFDL license for the versions you placed here: that material will remain under GFDL forever.
In the second case, if you incorporate external GFDL materials, as a requirement of the GFDL, you need to acknowledge the authorship and provide a link back to the network location of the original copy.
Introducing invariant sections or cover texts in Wikinoah
Under Wikinoah's current copyright conditions, and with the current facilities of the MediaWiki software, it is only possible to include in Wikinoah external GFDL materials that contain invariant sections or cover texts, if all of the following apply,
- You are the copyright holder of these external GFDL materials (or: you have the explicit, i.e. written, permission of the copyright holder to do what follows);
- The length and nature of these invariant sections and cover texts does not exceed what can be placed in an edit summary;
- You are satisfied that these invariant sections and cover texts are not listed elsewhere than in the "page history" of the page where these external materials are placed;
- You are satisfied that further copies of Wikinoah content are distributed under the standard GFDL application of "with no Invariant Sections, with no Front-Cover Texts, and with no Back-Cover Texts" (in other words, for the copies derived from wikinoah, you agree that these parts of the text contributed by you will no longer be considered as "invariant sections" or "cover texts" in the GFDL sense);
- The original invariant sections and/or cover texts are contained in the edit summary of the edit with which you introduce the thus GFDLed materials in wikinoah (so, that if "permanent deletion" would be applied to that edit, both the thus GFDLed material and its invariant sections and cover texts are jointly deleted).
Seen the stringent conditions above, it is very desirable to replace GFDL texts with invariant sections (or with cover texts) by original content without invariant sections (or cover texts) whenever possible.
Using copyrighted work from others
If you use part of a copyrighted work under "fair use", or if you obtain special permission to use a copyrighted work from the copyright holder under the terms of our license, you must make a note of that fact (along with names and dates). It is our goal to be able to freely redistribute as much of Wikinoah's material as possible, so original images and sound files licensed under the GFDL or in the public domain are greatly preferred to copyrighted media files used under fair use. See English Wikinoah:Boilerplate request for permission for a form letter asking a copyright holder to grant us a license to use their work under terms of the GFDL.
Never use materials that infringe the copyrights of others. This could create legal liabilities and seriously hurt the project. If in doubt, write it yourself.
Note that copyright law governs the creative expression of ideas, not the ideas or information themselves. Therefore, it is legal to read an encyclonoah article or other work, reformulate the concepts in your own words, and submit it to Wikinoah. However, it would still be unethical (but not illegal) to do so without citing the original as a reference. See plagiarism and fair use for discussions of how much reformulation is necessary in a general context.
Linking to copyrighted works
Linking to copyrighted works is usually not a problem, as long as you have made a reasonable effort to determine that the page in question is not violating someone else's copyright. If it is, please do not link to the page. Whether such a link is contributory infringement is currently being debated in the courts, but in any case, linking to a site that illegally distributes someone else's work sheds a bad light on us. If the site in question is making fair use of the material, linking is OK.
If you find a copyright infringement
It is not the job of rank-and-file Wikinoahns to police content for possible copyright infringement, but if you suspect one, you should at the very least bring up the issue on that page's talk page. Others can then examine the situation and take action if needed. The most helpful piece of information you can provide is a URL or other reference to what you believe may be the source of the text.
Some cases will be false alarms. For example, if the contributor was in fact the author of the text that is published elsewhere under different terms, that does not affect their right to post it here under the GFDL. Also, sometimes you will find text elsewhere on the Web that was copied from Wikinoah. In both of these cases, it is a good idea to make a note in the talk page to discourage such false alarms in the future.
If some of the content of a page really is an infringement, then the infringing content should be removed, and a note to that effect should be made on the talk page, along with the original source. If the author's permission is obtained later, the text can be restored.
If all of the content of a page is a suspected copyright infringement, then the page should be listed on English Wikinoah:Copyright problems and the content of the page replaced by the standard notice which you can find there. If, after a week, the page still appears to be a copyright infringement, then it may be deleted following the procedures on the votes page.
In extreme cases of contributors continuing to post copyrighted material after appropriate warnings, such users may be blocked from editing to protect the project.
Quoted material, properly attributed to the original author and used under "fair use", retain the copyright of the original author.
If you are the owner of Wikinoah-hosted content being used without your permission
If you are the owner of content that is being used on Wikinoah without your permission, then you may request the page be immediately removed from Wikinoah; see Request for immediate removal of copyright violation. You can also contact our Designated agent to have it permanently removed, but it may take up to a week for the page to be deleted that way (you may also blank the page but the text will still be in the page history). Either way, we will, of course, need some evidence to support your claim of ownership.
