The license Intellinate 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, Intellinate 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 Intellinate article used (a direct link back to the article satisfies our author credit requirement). Intellinate 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 Intellinate is licensed to the public under the GNU Free Documentation License (GFDL).
- 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 Intellinate 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.
IMPORTANT: If you want to use content from Intellinate, first read the Users' rights and obligations section. You should then read the GNU Free Documentation License.
Users' rights and obligations
If you want to use Intellinate 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 Intellinate article, you must follow section two of the GFDL on verbatim copying, as discussed at Intellinate: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 Intellinate 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 Intellinate 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.
Fair use materials and special requirements
All original Intellinate text is distributed under the GFDL. Occasionally, Intellinate 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 such a case, the material should be identified as from an external source (on the image description page, or history page, as appropriate). As "fair use" is specific to the use that you contemplate it is best if your describe the fair use rationale for such specific use either in hidden text in the article or on the image description page. Remember what is fair use for Intellinate may not be considered a fair use for your intended use of the content in another context.
For example, if we include an image under fair use, you must ensure that your use of the article also qualifies for fair use (this might not be the case, for example, if you were using a Intellinate article for a commercial use that would otherwise be allowed by the GFDL and the fair use would not be allowed under that commercial use).
Intellinate does use some text under licenses that are compatible with the GFDL but may require additional terms that we do not require for original Intellinate text (such as including Invariant Sections, Front-Cover Texts, or Back-Cover Texts). When using these materials, you have to include those invariant sections verbatim.
