Please copy stuff over from hawiki only if you own the copyright to it or it's licensed under the GNU FDL. Actually, don't at all until we've settled on a license. —Ashley Y 01:14, 9 January 2006 (EST)
GFDL is more convenient if we wish to import material from Wikipedia. Most Haskell library code is available under BSD. Opinions? —Ashley Y 01:14, 9 January 2006 (EST)
I think the content has to be such that it is easy to add things to Haskell implementations and libraries. As fptools and GHC are under the BSD3 license having the wiki with a more restrictive license can create problems. --EinarKarttunen 03:12, 9 January 2006 (EST)
There's a quick discussion of the various licenses at LWN.
I'll just note that if we start with a very liberal license, it can be tightened later. If we start with a restrictive license, there is no such option (short of contacting every author (or their heirs), and having them agree to it).
I don't care much for the FDL, it is too complex, and it's hard to grok how to deal with invariant sections, authorship (you are required to list at least five for derived works) etc.
I notice it is possible to interpret the wiki as a collection of independent works (see Udo Stenzel's recent post on the haskell list) - which wreaks havoc on any scheme requiring attribution. If so, I agree PD is probably less hassle.
(Of course, this assumes we are in a jurisdiction where PD is a meaningful concept - this excludes at least some European countries. I can't imagine this being a problem in reality, but perhaps there should be a textual note with a bit more detail?)
I've never heard of OPL, but have heard of the others, so perhaps OPL is too obscure. I would go for either public domain or BSD.
