* One license for the Wiki. If a contributor wants to put up material with a different license, then link to it as Udo suggested. (This also makes it clear that the link is to material that is not to be edited by others, whereas by definition the entire Wiki actively solicits editing by others.)
* That license should be maximally permissive. Anything viral defeats B(ii). Preferably even more permissive than BSD (e.g. no obligation to display a copyright notice. Who would the copyright notice be *to*?) I'm not fussy about the details. Just some way of saying "You can do what you like with this material".
We won't be able to include the Haskell 98 Report on the wiki (which is intended to replace the entire haskell.org site) because it has a more restrictive license. -- Ashley Yakeley
