Re: Internet Society's RFC license: DFSG-free or not?
It might be worth going back to Internet Society and asking if the
qualification on derivative works is intended to be operative or
informative. Remember you are dealing with a group that uses the term
request for comments to cover anything from reports of network outages
many years ago to the Internet protocol itself. I might be able to
make an argument that the set of things that could be a comment on an
RFC is broad enough to cover all derivative works. Certainly, if the
copyright holder intends this interpretation the license is fine.
