The license the Regional Knowledge Resource Kit (RKRK) 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, Regional Knowledge Resource Kit (RKRK) 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 Regional Knowledge Resource Kit (RKRK) article used (a direct link back to the article satisfies our author credit requirement). Regional Knowledge Resource Kit (RKRK) articles therefore will remain free under the GNU Free Documentation License (GFDL) 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 Regional Knowledge Resource Kit (RKRK) is copyrighted (automatically under the Berne Convention) by Regional Knowledge Resource Kit (RKRK) contributors and 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, no Front-Cover Texts, and no Back-Cover Texts.

Contributors' rights and obligations

If you contribute material to the Regional Knowledge Resource Kit (RKRK), 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 must be in a position to grant this license, which means that either

• you hold 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 copies of materials that you place here; these copies will remain under GFDL until they enter the public domain.

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.
