Forum:Licensing update

Summary: Do you have any views on migrating from GFDL to CC-BY-SA?

The text of most Wikia wikis is available under a free content license called the GFDL. This license was chosen because it's the license that Wikipedia uses. Wikipedia uses it because it was the best option when they launched in 2001. But now there is a better suite of licenses from the Creative Commons. The latest version of the GFDL (1.3) allows a one-time migration from GFDL to the Creative Commons Attribution Share-Alike License (CC-BY-SA). This license essentially gives everyone the same freedoms that the GFDL does - the content can be used for any purpose, derivatives must be released under the same free license, and attribution must be given.

Some of the advantages in switching license would be to remain compatible with Wikipedia (assuming they do switch), being able to share text with the many projects that already use this Creative Commons license, having a license that is simpler to use and understand, having a license which has been officially translated into many languages (the GFDL is only official in English).

Quoting from Wikimedia's information on this:
 * "The proposed license update is designed to achieve greater interoperability and greater re-use of free knowledge world-wide in service to our vision: a world in which every single human being can freely share in the sum of all knowledge."

Tomorrow, Wikimedia will begin a vote for their editors to give an opinion on the proposal. Anyone with at least 25 edits to any Wikimedia project prior to March 15, 2009 can vote. (Note that Wikia isn't a Wikimedia project, so edits here are not counted.)

Any such migration would only affect wikis that are already under the GFDL.

More details can be found at Licensing update and FAQ. Any dual-licensing discussions you see there need not affect Wikia sites (though of course such arrangements can be made on a per-wiki basis like now if desired).

At this stage, I'm just interested to know your opinion on the proposal of migrating from GFDL to CC-BY-SA.

 * I personally think it is a good idea, especially if it makes things easier for sharing information and for users to understand the licensing realm. I've looked into the situation a bit in the previous weeks, and it appears to be the correct thing to do &mdash; and I haven't seen anything negative that could potentially come out doing this. Other people's thoughts or comments will hopefully provide some more constructive feedback on this.

I dont think this wouldn't really be usefull for fr.guildwars since the licence of GuildWiki is not exactly the same. They have the NC clause. So, if fr.guildwars would change, that would mean we wouldn't able to translate any wiki at all (the Official wiki been in GFDL). Or maybe i'm misunderstanding something. — TulipVorlax 01:05, 12 April 2009 (UTC)


 * Do you know whether the official wiki intends to switch license? As that one is GFDL, they too have this option until August. Angela (talk) 12:29, 12 April 2009 (UTC)


 * I think the main differences need to be highlighted before I can comment. -- LordTBT Talk! 04:10, 12 April 2009 (UTC)


 * If you would like to see the detailed differences, the full text of both licenses can be found at GFDL and CC-BY-SA. One advantage to the Creative Commons one is that they have a nice summary of the license here. There is also a detailed Wikipedia article on the GNU Free Documentation License and on the Creative Commons licenses generally. The specific Creative Commons license that is allowed to replace the GFDL is one that is defined as "free" by the Free Content Definition project. Angela (talk) 12:27, 12 April 2009 (UTC)


 * As Iunderstood, it won't be a Change GFDL license to a CC-BY-SA license, but a Relicense the content under both GFDL 1.3 and CC-BY-SA 3.0 licenses. Some highlights:
 * The change must be made before 1 August 2009, as required by GFDL 1.3 (see FDL1.3 FAQ, section Q. What is the purpose of the two different dates in section 11? Why did you choose those specific dates?.
 * Content imported from another wiki licensed under a GFDL1.2 only license must not be re-licensed, and if a relicense is made in the wiki, it should be deleted.
 * Conted imported from another wiki licensed under a GFDL 1.2 or (at your option) any later version could be re-licensed under the dual-license. But only if it was put in a public wiki before 1 November 2008. See FDL1.3 FAQ, section Q. Exactly what material can be licensed under CC-BY-SA 3.0?.
 * About TulipVorlax comment, if GuildWiki uses GFDL 1.2 or any later version it would be possible to do the dual-licensing, but only content since 1 november 2008 and no further content can be imported since this date.
 * In my opinion, it would be good to give each wiki the decision to switch to a dual license like wikipedia, but not impose it to all wikis --Ciencia Al Poder (talk) -WikiDex 11:01, 12 April 2009 (UTC)


 * On Wikipedia, if the decision is to switch, then each article will be both GFDL and CC-BY-SA until someone imports some CC content into an article, at which time it becomes CC only. You would not be allowed to import GFDL-only content into Wikipedia in future. This dual-licensing step is not necessary for other wikis, but of course is an option if anyone needs it.


 * Original content added to a wiki after November can be relicensed, but if you imported GFDL content from somewhere that was not a wiki after November, that content can not be relicensed. I'm sorry that this sounds so complicated. The reason for it is that the Foundation that writes the GFDL did not want someone suddenly adding lots of GFDL software manuals to a wiki after this was announced purely with the intention of re-licensing them!


 * If any wikis do want to dual-license, then please let me know. My personal opinion is that it's a complicated step with no benefit to the wiki, but I'm sure there will be some exceptions. (In fact there already are 2 or 3 Wikia sites that have chosen dual-licensing) Angela (talk) 12:27, 12 April 2009 (UTC)
