[Mypaint-discuss] Licensing policy: a proposal
We should write down some simple policy for which licenses we accept into the MyPaint main distribution, primarily to keep things simple for coders and artists. What about the following, expressed in FAQ style? --8 DRAFT NOT OFFICIAL * DRAFT NOT OFFICIAL * DRAFT NOT OFFICIAL Q: What licenses should I use when contributing to MyPaint? A: If you want your contribution to go into the official MyPaint distribution, you need to pick a license: 1. All program code and supplemental data files should be GPLv2[1] or LGPL. This includes program icons and artwork for display within the program. 2. Supplemental artworks and promotional material included in the distribution should be CC-Zero, CC-By, or CC-By-SA, version 3 [2]. 3. Elements which are highly likely to be reused by artists in the creation of new works[3], e.g. bundled brushes[4] or background texture images, should be licensed as CC-Zero or Public Domain. You'll get attribution in the official distribution, of course :) DRAFT NOT OFFICIAL * DRAFT NOT OFFICIAL * DRAFT NOT OFFICIAL ---8--- Please pick apart point by point. The final tone should be friendly and not too lawyery :) [1] which might in due course be globally updated to GPLv3, as the license permits. Before you ask :) [2] CC licenses (version 3) are almost certainly DFSG-compatible. Versions 2.5 and below are not. We'd really like Debian to pick us up. [3] Background elements are very likely to be reused without the artist giving any thought to licensing. And they shouldn't have to. Therefore it is vital that the license permit that *and* re-licensing. [4] I initially thought that brush settings might be best expressed best as 1. since they're little programs. However brush settings are copied into strokemaps during routine operations, so when you change a setting, paint with the brush and save as .ORA then - *booya!* - you just made a derived work[5]. So it's best if all core brushes are CC-Zero. [5] there's a chance that this might be mere aggregation, which is a possible escape from this potential trap. We could state that *in our opinion* that's what it is, always, and thus accept GPLed brush code. In fact we may have to do that anyway for grandfathering reasons :/ -- Andrew Chadwick ___ Mypaint-discuss mailing list Mypaint-discuss@gna.org https://mail.gna.org/listinfo/mypaint-discuss

This is the license used for existing code, and allows downstream recipients to chose under which version of license they want to distribute the work, and allow us to move to GPLv3+, if we would like to. -- Jon Nordby - www.jonnor.com ___ Mypaint-discuss mailing list Mypaint-discuss@gna.org https://mail.gna.org/listinfo/mypaint-discuss
Re: [Mypaint-discuss] Licensing policy: a proposal
I see that is a good idea to have this kind of help to choose license, thanks to all for the support. This way we can center our energies on create stuff for this app. We are growing and this will be helpful for other users too. take care 2011/3/7 Jon Nordby jono...@gmail.com On 7 March 2011 14:17, Andrew Chadwick (email lists) andrewc-email-li...@piffle.org wrote: We should write down some simple policy for which licenses we accept into the MyPaint main distribution, primarily to keep things simple for coders and artists.

Maybe just mention public domain here, and give an example statement how to do this later down, using CC0. Background texture must be public domain. * Brush packs should be licensed as for background texture images. Brush packs should also be placed into the public domain. Alternatively, you can use CC-By 3.0 or CC-By-SA 3.0; the pack's internal brush settings[1] should still be licensed CC0 1.0 or Public Domain, however. Okay, but we absolutely need an example statement for this, for copy/paste. (I'd say only provide one for the CC-By 3.0 variant.) -- Martin Renold ___ Mypaint-discuss mailing list Mypaint-discuss@gna.org https://mail.gna.org/listinfo/mypaint-discuss
