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)
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)
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)
