Hi

Did anyone here know if the GPL+ v2.0 /v3.0 is compatible with the
CC-BY v3.0 (unported)
http://creativecommons.org/licenses/by/3.0/

I only found here
http://wiki.debian.org/DFSGLicenses#Creative_Commons_Attribution_Share-Alike_.28CC-BY-SA.29_v3.0


that the CC-BY-SA v3.0 is compatible, but no mention of the CC-BY
v3.0 My understanding is that the CC-BY v3.0 has less restrictions
then the CC-BY-SA version, but I'm a bit unsure.

Background: I would include some work which is under the CC-BY v3.0
to my project, which is under the GPL+ v2.0 (or later). I wouldn't
violate the DFSG, so I would make sure there is no issue at all when
I'm do so. The Author of the CC-BY v3.0 files is fine with my wishes.

any hints?

you can derive a version of the cc-by work, eveb with no
modifications. You just need to give it a different name and credit
the original author. Then you can change the license to a compatible
one. I suggest cc by sa since this adds GPL compatible copyleft.
Changes on your version need to be relicened as ccbysa then while the
original ccby version stays untouched.

This is a general principle: a work which is as freely licensed as cc
by, public domain or compatible can be relicensed as-is with a more
strict one.
Do you believe that it is needed to re-license it, I would prefer to
leave the license untouched, and include it "as it is", if possible.
My impression now, after reading all the posts about this theme on the
debian mailing list is, that they didn't make a difference between
cc-by-sa or just cc-by. They just mention the cc-by-sa on the wikki
page, because it is more restricted, but open enough.
Oh, what a hell, those license jungle. :-(
yes. That is possible. You can do whatever you want with cc by except
not giving credit.

My suggestion assumed you want to be able to modify things and thus
are interested in copyleft.

Well, no, there is no need to modify, and I would give credits,
already done on the project page, even if I didn't have upload the
files to our repository and will do in the about box as well, when I
upload them.

I just was unsure what the license really mean, and if it is DFSGL
compatible. Now, after investigate some time in research, I know, that
the debain folks itself didn't know that for themselves, but the usual
practice is to accept cc-by since version 3.0 (2.5).

The best is happen at least,
I receive the permission from the original author, to re-license the
files and distribute them under the terms of the GPL. That's so great,
leave all those license jungle behind me.
:-)
You didn't even need the permission. That is what I wrote at first: CC-by 
implies that you can relicense the work with a more strict license at any time. 
From cc-by-sa over GPL up to closed source. As long as you keep the authors 
name around.

Since I don't know the actual code/object/thing we are talking about you might 
have stepped in the jungle yourself now:
If that work is a binary work like audio data then the GPL is the wrong license. GPL is 
all about source code and its binary form. You can't simply redifine other data as source 
code and then say "the rest is GPL".

If the original work was already fitting for CC-by (and not a mislicensed piece 
of code) then CC-by-sa might be much more appropriate, since it is the 
binary-data equivalent of the GPL.

In any case and bottom line: All that matters not if you don't modify.

Have fun!

Nils
umpf, back in the jungle, or what?
Indeed we talk about (impulse response) wav files.
I've contacted now the debian maintainer from our package, to ask him what debian will prefer / accept.

thanks for your informative input Nils, I know you have fight some time with the possible licenses of audio files for sample library’s, so I guess you are right with what you said.

hermann
