I thought I'd covered the bases fairly well, but I'll make sure I do a more
thorough job in future of enumerating the issues involved.

Personally, mentioning that there aren't any DFSG issues noticable is
useful, because it means that part of the necessary conditions are
satisfied.  I can see, though, that only saying "there are no DFSG problems"
only gives the OP half the story.

No.  The requirement is quite definitely non-free.  It also doesn't consider
modified models at all, which you may *want* to have renamed, depending on
the modification.  :-)

Just use a free license and then *request* that people use the same name and
background in their games.  They probably will honor your request.

That's because I was attempting to point out potential problems in your
approach, not challenge your findings.

I think starting or ending an analysis with "well, I can't find anything
that directly contravenes the DFSG" is a risky approach to take.

DFSG-conformance is a necessary but not sufficient condition for a work
to be Free Software.

I didn't mean to give personal offense.

Sigh.  Thanks for that, Branden.  Keeping d-legal as happy and healthy as
ever.

I'm not trying to read the DFSG as narrowly as possible.  I was merely
observing that I couldn't find a clause of the DFSG that really stated that
what the OP was proposing was non-free.  You conveniently cut the parts of
my message that gave some possible DFSG problems, depending on
interpretation, and some practical problems that may be significant,
depending on the licensor's interpretation of the given statement.

Then you're not reading it correctly.  The "G" in DFSG stands for
"Guidelines".

We pledge to keep Debian 100% Free Software, not read the DFSG as
narrowly as possible.

I can't find anything which immediately contravenes the DFSG.  You might
have a problem with DFSG 10 (if the name and background of the "character"
would be a considerable chunk of information to have to include in your
software), although I think it's a stretch.  The other problem is going to
be modification -- the licence to the model must allow free modification and
redistribution of modified forms, and how modified should the work be before
we can change the name?  If never, then it's going to be a bit weird with
all these different-looking characters with the same name and background...

Basically, I can't think of anything which is immediately problematic, but I
can think of plenty of potential problems that could occur.

Are you looking at this licence term from a producer or consumer point of
view?

This would render the licence non-free, since you restrict modification
(the background can't be changed). I am not sure about the name thing,
and leave that to debian-legal.

> The idea is to create a recurrent character in different games, like

I'd suggest you to keep the licence free, and especially use a proven
one, like the MIT or GPL licences. You can then add a note, that does
not belong to the licence, stating what you intend. Most people will
stick to that - the world is not as bad as it seems :-)

about licenses for 3D models

2004-04-20 Thread Jiba
Hi all,

About a character 3D model, I am wondering if such a statement can occur
in a free license:

"You can re-use the model, but you must keep the name of the character,
and his background".

The idea is to create a recurrent character in different games, like
Mario of Link.
