[Mediawiki-l] Licensing of extensions

[Brianna Laugher]

Hi,

On mediawiki.org one of the parameters on {{extension}} is "License".
Is this to be interpreted as extra licenses in addition to the GPL? I
think that because MediaWiki is GPL, extensions must also be GPL.

http://www.fsf.org/licensing/licenses/gpl-faq.html#GPLModuleLicense says:

++++
If I add a module to a GPL-covered program, do I have to use the GPL
as the license for my module?

    The GPL says that the whole combined program has to be released
under the GPL. So your module has to be available for use under the
GPL.

    But you can give additional permission for the use of your code.
You can, if you wish, release your program under a license which is
more lax than the GPL but compatible with the GPL. The license list
page gives a partial list of GPL-compatible licenses.
++++

So does it seem safe to assume that all published extensions must be
GPL, + whatever else is specified?

thanks,
Brianna
