Upgrade license to CeCILL-B version 2.1+? #1385

Closed brylie closed 2 years ago

brylie commented 4 years ago

We are considering integrating iTowns into a project that is licensed as AGPL. The AGPL license was chosen since our project contains components that run only on a server and we want to preserve the users' right to access the server source code.

While iTowns uses CeCILL-B license version 1.0, this may not have strong compatibility with the AGPL (or EUPL). Later versions of CeCILL-B, namely 2.1, have improved compatibility with AGPL and EUPL licensed.

Please consider upgrading the iTowns license to include CeCILL-B 2.1 (or any later version).

Thanks for the suggestion ! Unfortunately, there is no CeCILL-B 2.1 license. It is either CeCILL-B (the one we are using), either CeCILL 2.1.

The one you are interested in is CeCILL 2.1 I assume. It is a change that could be done, but we need some validation on this before doing so. We'll keep you updated !

IIRC, we dual-licensed iTowns under CeCILL-B and MIT to avoid compatibility issues with other licenses (MIT is compatible with AGPL) while still having a license under the French laws (the additional "citation" clauses were not what mattered).

IANAL but I'd say iTowns can be included in AGPL software because it is licensed under MIT.

OK, thanks.
