As far as I can tell, Wikitravel content can be copied to Wikipedia, is that correct? Wikipedia, by using GFDL, has even tighter restrictions against distributors restricting other people's rights on how to use the content as far as I know, so copying content from Wikitravel to Wikipedia should not breach any of Wikitravel's distribution restrictions. Is this correct? Either way, I guess it's a question which comes naturally, so I think the answer to this should be included in this article. --Gutza 06:59, 6 Oct 2003 (PDT)
Actually, although I'm no lawyer, I don't think this is quite correct. Because Wikitravel content is covered under a "share alike" Creative Commons license, derivative works would formally have to be under such a license, wouldn't they? Now, one could probably argue that the GFDL, since it allows copying the work and commercial profit to be made from such copies is similar enough to Attribution-ShareAlike to qualify. Maybe if a lawyer is reading this, they could give their opinion? Ctylemay 11:46, 6 Oct 2003 (PDT)
IANAL, but my understanding from talking to Creative Commons people, Wikipedia people, and FSF people, is that the Attribution-ShareAlike and GFDL are not compatible in any way (besides normal fair use provisions). This is stupid and wrong, and it's a big mistake that needs to be corrected by the creators of both licenses. Considering that FSF recommends the CC licenses, and vice versa, it seems stupid to have them incompatible. Right now, we can't do much about it -- I recommend that anyone who's got a beef with this should write to the FSF and to Creative Commons and let them know it's an issue. -- Evan 09:46, 7 Oct 2003 (PDT)
The FSF and CC are aware of this problem and are working to resolve it. Meanwhile, the BY requirement in CC-BY-SA seems to me to be unsuitable for wikis, where dozens of people might hash over any given paragraph or sentence at various times. Do you really want to require a printed page to also contain the change history so everyone gets credited? I like the egoless nature of wikis and enjoy contributing anonymously. --anonymous wikipediac
We actually have on-page attribution built into MediaWiki (the software used for Wikipedia and Wikitravel), which is enabled here and not at Wikipedia. You can see it at the bottom of each page. Each user is attributed either with their real name, if provided (another feature disabled at Wikimedia sites, by the way), or their user name, or just as "anonymous user" if they're not logged in. If there are too many to credit at the bottom of the page, we credit them on a separate page. I think we still have a few more steps to perfect this process -- I'd like to have on-page attribution for image contributors, too -- but for now it's working pretty OK. --Evan 04:29, 29 Dec 2004 (EST)
The later versions of Creative Commons licences allow contributors to specify 'attribution parties' to receive attribution instead of themselves, so with a recent CC licence, you could require attribution to the wiki if you wanted to be anonymous. --Carl
I'm not sure I completely understand this, but it seems that Wikitravel is using CC-BY-SA 1.0. When the FSF and/or CC fix their licenses to make them more compatible, the older versions still exsist. The GNU GPL for example has an "or any later version" clause, but when you say CC-BY-SA 1.0, it seems that a later versions is not OK. I guess Wikitravel should be using CC-BY-SA 1.0 or any later version? Or is this not an issue? Comments? Luke Stodola 25 Jan 2004
The GPL does NOT have an "or any later version" clause. Some GPL'd programs have that clause. Some GFDL documents have that clause too. I don't know if Wikipedia has it.
Section 9 of the GPL version 2 specifies what "or any later version" means. Section 10 of the FDL is almost identical. Authors can choose whether or not to allow later versions. --Evan 04:29, 29 Dec 2004 (EST)
Hmmm. I think you have answered wrong part of the question above.
Let's assume that CC-BY-SA 9.0 will become GFDL compatible. Problem is that Wikitravel content will not be automatically available under CC-BY-SA 9.0. All the current content is under CC-BY-SA 1.0 and will always be unless all authors agree to move it to CC-BY-SA 9.0. So the statement If and when the CC licenses become GFDL compatible, other Free Content authors can include Wikitravel content into their work and a few similar seems to be false. --JanSlupski 22:16, 4 April 2006 (EDT)
Version 1.0 of CC BY-SA doesn't include an 'or any later version' clause. Versions 2.0 and later do. --Carl
I guess the problem is that we see "share alike" as a way to avoid having our contributions be amalgamated into a fully copyrighted derivative work, but maybe no one thought of the other restrictions that go along with the way this is done. For example, my understanding is that a derivative of a BY-SA work could not be issued under a BY-NC-SA license! So anyways, I've pointed this out on the mailing list at creative commons and we'll see what happens. -- ctylemay 22:00, 7 Oct 2003 (PDT)
Thanks a whole bunch; I saw your post on cc-licenses, and it was succinct and cogent. I think if people from the Wikipedia and Wikitravel communities put some pressure on CC and FSF, we can see compatible licenses in future versions. It's necessary and valuable. Thanks for the work, again. -- Evan 22:34, 7 Oct 2003 (PDT)
The fact that you can't relicense from BY-SA to BY-NC-SA is intentional; BY-SA, like the GNU licences, says "You're free to use this, even commercially, provided you give everyone else the same rights". Adding a non-commercial restriction for downstream users would be totally inconsistent with this. If you really want your work to be combinable with work under BY-NC-SA as well as BY-SA, you could dual-license it (to keep some kind of copyleft), or use CC Attribution-Only.
I already got a response from Glen Otis Brown (the executive director at Creative Commons.) Basically, it looks like they're working on it, and that future versions of share-alike licenses may alow inclusion of material into derivative works under other share-friendly licenses. So sit tight Gutza, soon the transfer of content may be easier, even though for now it is not possible. -- CL 22:59, 7 Oct 2003 (PDT)
Re: GFDL "requiring that all copies of the work be distributed with a copy of the GFDL and a changelog, as well as "transparent" (i.e. source) versions if you distribute over 100 copies", isn't the inclusion of the URLs of the GFDL, the changelog, and the source version, considered to meet this requirement?
Not by my reading of the GFDL, no. I don't think it's in the letter or the spirit of the GFDL. The FSF specifically recommends against using the URL-based referencing in the Creative Commons licenses. -- Evan 12:47, 29 Oct 2003 (PST)
Wikipedia breaks about ten terms of the GFDL and its poor governance and use of SQL dumps as the only way to move masses of articles, means it really isn't providing source transparency either. It's technically possible to sue the "Wikimedia foundation" and force them to (a) meet these terms or (b) sign a cross-licensing agreement for a license that actually does satisfy these terms.
Not that this is necessarily the best way! But this really isn't a problem. There are lots of groups printing out 1-2 page Wikipedia articles and assuming that the URL on the pages meets those requirements mentioned. They are not at all wrong to do so, especially since Wikipedia itself can easily meet all of those requirements at one URL, if it actually bothered to make it a priority...
Given the two options -- keeping our legal tail covered, and those of our users, rather than freely being able to borrow from Wikipedia at will -- I'd prefer the former. Most Wikitravellers seem to agree. That said, you are welcome to label your contributions as being dual-licensed, as long as you're not basing them on other people's by-sa licensed work. -- Evan 12:47, 29 Oct 2003 (PST)
OK, so, I got burnt with this discussion, since some people apparently want to dual-license their work. I've created an article on how to dual-license things here; comments and modifications welcome, of course. -- Evan 09:31, 2 Nov 2003 (PST)
CapitanCook / World66
Browsing the meta pages, I found an inacurrency here. You state that CapitanCook is licenced under the GFDL, although the link goes to to World66 which is licenced under Creative Commons. Yann 09:50, 19 Jan 2004 (EST)
HOLY CRAP! You're right! This is a relatively new development -- everything used to be GFDL there. WOW! This is cool news. --Evan 10:32, 19 Jan 2004 (EST)
Good, isn't it? I only noticed the other week. Although I'm interested to know how precisely how valid such a relicensing is. --Earle 11:27, 25 May 2004 (BST)
"Creative Commons is [are?] planning to issue a new revision of their [its?] suite of licenses some time in the winter of 2003-2004." - I know it's still a bit wintry here in Wellington some mornings, but one wonders whether that sentence needs serious attention by someone in the know. Robin Patterson 01:10, 8 Sep 2004 (EDT)
Seems that the wait is over. Or has the 2.0 SA license been around for a while? Caffeine 23:08, 2 Oct 2004 (EDT)
I rolled back an edit that changed the list format in the first section so that each list element was further indented. I didn't see the point, and I didn't like how it looked. Mostly, I thought it was confusing -- suggesting that each group was a sub-group of the previous one. So, I rolled it back. --Evan 15:11, 18 Jan 2006 (EST)
