I agree this is tricky; the ICC specification only provides a
"Copyright" field, and this is clearly designed for proprietary
profiles that cannot be redistributed, rather than open source
profiles that specify a licence with conditions. It's also something
to bear in mind that something like the bluish profile is only really
9 floating point numbers that defines a 3x3 matrix, and so the
"copyright" and "licence" concept is very loose.

I'm open to relabelling the profiles with a new correct profile
string, or adding some kind of metadata encoded in the profile
PROFILE_licence and then leave the Copyright as just the copyright
rather than trying to encode two things in one string.

Sure, I'm open for ideas -- I think clarifying this now is a very good idea.

Well, then I owe you a beer or two. :-)
