I'm not sure how things work legally, but the wiki itself has all of the authorship information in it. Simply acknowledging that something came from the Haskell wiki would allow anyone to identify the underlying source given the ability to crawl around in page histories. I wouldn't want to have to acknowledge in any finer detail than that myself. I'm not sure if that is something that has to be addressed in the license itself or not though.
John PS - please forgive my earlier attempt at lame humor when discussing the wiki. When talking about copying from the wiki I mentioned Paul Hudak and forgot a much needed smiley after his name. Paul is most definitely a writer of highly original content in the Haskell world and has absolutely no need to do anything untoward with the contents of haskell.org. Furthermore, the community should know that it is Paul that has to pay for haskell.org itself - something we should all be grateful for. _______________________________________________ Haskell mailing list Haskell@haskell.org http://www.haskell.org/mailman/listinfo/haskell
