Information for text contributors
To grow the commons of free knowledge and free culture, all users contributing to the FlightGear wiki are required to grant broad permissions to the general public to re-distribute and re-use their contributions freely, as long as the use is attributed and the same freedom to re-use and re-distribute applies to any derivative works. Therefore, for any text you hold the copyright to, by submitting it, you agree to license it under the GNU GPL. Please note that this license does allow commercial uses of your contributions, as long as such uses are compliant with the terms.
As an author, you agree to be attributed in any of the following fashions: a) through a hyperlink (where possible) or URL to the article or articles you contributed to, b) through a hyperlink (where possible) or URL to an alternative, stable online copy which is freely accessible, which conforms with the license, and which provides credit to the authors in a manner equivalent to the credit given on this website, or c) through a list of all authors. (Any list of authors may be filtered to exclude very small or irrelevant contributions.)
Information for non-text media contributors
Non-text media on the FlightGear wiki are available under a variety of different licenses.
Information for re-users
Please follow the guidelines below.
Re-use of text:
- Attribution: To re-distribute a text page in any form, provide credit to the authors either by including a) a hyperlink (where possible) or URL to the page or pages you are re-using, b) a hyperlink (where possible) or URL to an alternative, stable online copy which is freely accessible, which conforms with the license, and which provides credit to the authors in a manner equivalent to the credit given on this website, or c) a list of all authors. (Any list of authors may be filtered to exclude very small or irrelevant contributions.) This applies to text developed by the Wikimedia community. Text from external sources may attach additional attribution requirements to the work, which we will strive to indicate clearly to you. For example, a page may have a banner or other notation indicating that some or all of its content was originally published somewhere else. Where such notations are visible in the page itself, they should generally be preserved by re-users.
- Copyleft/Share Alike: If you make modifications or additions to the page you re-use, you must license them under the GNU GPL Version 2 or later.
- Indicate changes: If you make modifications or additions, you must indicate in a reasonable fashion that the original work has been modified. If you are re-using the page in a wiki, for example, indicating this in the page history is sufficient.
- Licensing notice: Each copy or modified version that you distribute must include a licensing notice stating that the work is released under GNU GPL and either a) a hyperlink or URL to the text of the license or b) a copy of the license. For this purpose, a suitable URL is: http://www.gnu.org/licenses/old-licenses/gpl-2.0.txt
- For further information, please refer to the legal code of the GNU GPL.
Re-use of non-text media:
- Where not otherwise noted, non-text media files are available under various licenses. Please view the media description page for details about the license of any specific media file.
