LibreCAD license review

Hello all,

Development is very busy now with tremendous new features that will be
unveiled in LibreCAD 2. Check out what's going on at github and IRC to
get a preview.

I've been periodically watching the progress to make sure everything
stays within license compliance. Some issues we should resolve:

1) what is the license and copyright for jwwlib/? "dl_jww-copy.cpp"
says "Copyright (C) 2001-2003 RibbonSoft. All rights reserved." and
licensed GPLv2, but I can't find that file from anything RibbonSoft
distributes. The other files are not licensed at all. Could we check
into the copyright and license for that library (make it GPL2+ i.e.
GPLv2 or greater)? If we're not planning on releasing this ever (if
the new dxf library doesn't need it, for example), they we don't have
to worry about it.

2) I already talked to Rallaz, but ttf2llf has the same problem (it
says copyright RibbonSoft, but I don't see anything at RibbonSoft's
site about it; and the license is only GPLv2 not GPLv2+)

Cheers,
Scott

Hi Scott,

I just added to repository the following licenses:

GPLv3 and Apache2

because the newly added WenQuanYi fonts are covered by Apache2 or GPLv3.

Thanks

Scott,

I will check the jww licenses but I am pretty sure they are not added by Ribbonsoft

and I think they where added to the header because the person who wrote the software thought

this was the right way todo. I will see if I can contact the person (I think he is chinese or Japanses).

The code was found on a a version of SF.

If I cannot get in contact with the person I think it's fine to remove it again. I only know one person

who is interested in it.

I will let Rallaz answer number 2)

Thanks everyone. I'm trying to keep the LICENSE file up to date with
everything we have. This will make it easier for release and
eventually for upgrading licenses. If you see anything wrong with
LICENSE, please update it or correct it too.

Cheers,

Re: LibreCAD license review

inverse response:

2) the utility program ttf2lff is a modification of ttf2cfx:
http://www.qcad.org/rsforum/viewtopic.php?t=415
some parts have my copyright, but unmodified parts have copyright from RS.

Is posible to mix licenses in one sorce file? like:
** code from Rallaz license GPLv2 or greater
** code from RibbonSoft license GPLv2

1) the jwwlib files do not have any license and copyright, except:
dl_jww.h -> based in dl_dxf.h from dxflib
dl_jww.cpp -> based in dl_dxf.cpp from dxflib
original repository:
http://en.sourceforge.jp/cvs/view/jw-qcad/cad-qt4/jwwlib/src/

It is possible to mix licenses, but until all the original code is
removed it is GPLv2 only. Mix licenses allows for future upgrading or
changing over to new licenses while maintaining compliance in the
short-term.

If it's based on dxflib, it should have at least the same license as
dxflib (since it is GPL.) It would be better to add the correct
license information and copyright information.

I'd be comfortable saying it is GPLv2-only since it is a derived work
from dxflib.

Thank you.

I have asked about the jww license but I didn't got a response back.

I will send him a reminder mail next week.
