More detailed info would definitely be helpful. I've also gone ahead and added the board list via CC since this was intended to go to the board.

Just to throw out there, I am aware of a couple things. At least Jon Cruz (I believe also Felipe Sanches) has committed multi-licensed code at some point. At least some of the MPL was also licensed as GPL. Regarding the GPL2 vs 3 issue, we still haven't run across anything that explicitly states GPL2 only and what is there says GPL2 or later... so according to discussions with SFC, we are technically still a GPL2 project just with some GPL3 code.

One example of a multi-licensed file can be viewed at http://bazaar.launchpad.net/~inkscape.dev/inkscape/trunk/view/head:/src/ege-...

Cheers, Josh

Hello Jan,

I personally am not aware of any licensing issues that we have in Inkscape, thanks for bringing this to our attention! Do you have a report that has more detail of which files/directories are which license so we can look into it with more detail?

Thanks, Ted

Hello Inkscape board,

We are planning to use inkscape. Thus we scanned the source code of inkscape 0.48.4 for OSS licenses. So we found out that inscape 0.48.4 includes the following licenses:

GPL 2.0

GPL 3.0

LGPL 2.1

MPL 1.1

Apache License 2.0

creativecommons Attribution-ShareAlike 3.0 Unported

BSD-2-Clause

BSD-3-Clause

MIT

Zlib

W3C

Unfortunately there are license incompatibilities between some on the licenses. E.g.:

Apache 2.0 <-> GPL 2.0

GPL 2.0 <-> GPL 3.0

MPL 1.1 <-> GPL 2.0 + GPL 3.0 + LGPL 2.1 + Apache License 2.0

This leads to a serious problem: The creator of the code published under Apache License 2.0 can prohibit a publishing of his code under GPL 2.0. So we are not allowed to publish it at all.

So here are my questions:

Is the community aware of this problem?

Is there a general statement regarding this topic available?

Are there any counter measures planned/implemented?

Kind Regards

Jan Kanefeyer
