Does the "at arm's length" case apply for GRASS GIS and GRASS GIS<br>
addons? Do GRASS GIS core and GRASS GIS addons considered to operate as<br>
one?<br></blockquote><div><br></div><div>Please note that there is a difference between creating a custom GRASS GIS module and contributing that module to GRASS GIS Addons repository. For "addons" we, at least currently, require 100% compatibility with the "core", i.e. GPL >=2 (SPDX: GPL-2.0-or-later), to be able to move code freely between these two (without even a need to think about the license at that point and being on the safe site when distributing everything).<br></div><div><br></div><div><a href="https://trac.osgeo.org/grass/wiki/RFC/2_LegalAspectsOfCodeContributions">https://trac.osgeo.org/grass/wiki/RFC/2_LegalAspectsOfCodeContributions</a><br></div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

If yes,<br>
<br>
1. this would mean that the GPL and the EUPL cannot be combined, in<br>
the case of GRASS GIS addons.<br></blockquote><div><br></div><div>I agree with Moritz that this would be best answered by those would created EUPL (i.e. some "open source office" in European Commission) or alternatively by Free Software Foundation Europe (<a href="https://fsfe.org/">https://fsfe.org/</a>). <br></div><div><div></div></div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
<br>
2. would the GRASS GIS team consider to add a similar "compatibility<br>
clause" to effectively make both licenses 100% cross-compatible?<br></blockquote><div><br></div><div><br></div><div>This would count as changing the license. Changing the license would mean getting approval from all past contributors which would be very hard, close to impossible. (Changing to a later version of GPL is of course a different story because of the "or later" part.)<br></div></div></div></div></div></div></div>
