[Open-access] Green Gold Gratis Libre

[Mike Taylor]

This almost all looks right to me.

Yes.  It might be worth making the point that CC-BY is a libre licence
(the canonical one, really) whereas CC-BY-NC is merely a gratis
licence.

(We probably don't want to get into discussing CC-BY-SA, since there
are validly differing opinions on where that is more or less free than
CC-BY, just as people disagree over whether the GNU GPL or Modified
BSD licence is more free for software.)

Yes.  This doesn't exhaust the possibilities, either.  For example,
the maintainer of a green subject-specific repositiory might reposit.
Basically, I think it's anyone but the publisher.

Since these aspects are the same for Green and Gold, it's better not
to list them twice, but just to have a separate section at the end on
what neither Green nor Gold guarantees.

In the end, the ONLY difference between green and gold is who makes
the article physically available.  In gold, it's the publisher, in
green it's someone else.  You could characterise the difference as:
does the publisher actually HELP, or merely not hinder?

On permanence: there is a difference between how permanently something
has access rights (e.g. releasing under any CC licence is irrevocable)
and how permanently something is hosted.  In practice, anything CC'd
is free forever because it gets mirrored across the world.

Again this is nothing to do with green vs. gold.  It's about the licence.

Yes.  Gold-CC-BY-SA is also possible, e.g. Elsevier sponsored
articles.  (BTW., I have a blog post about there coming out this
evening.  Anyone who doesn't follow my blog
http://svpow.wordpress.com/ probably should at the moment -- it's
almost entirely about open issues.)

That will be helpful.
