When I have this string in License tag in spec: Good License or Bad license Then the result is Good license and the package is allowed to be in Fedora, right?So first of all if I change your question to be about the actual underlying license terms of the package as opposed to the representation in the spec file, I believe the answer must be "yes" and there are probably a lot of examples of this in Fedora. (Think of any arbitrary package that says it's under some FOSS license and also says informally that proprietary licenses are also available.) With the spec file, though, I believe there is an inconsistency in how Fedora deals with this, but this is just a casual impression. On the one hand, there is the common case of traditionally-licensed Perl modules (typically, a dual license involving unversioned GPL and a license identified as the Artistic License 1.0 [which I realize exists in multiple forms, but let's ignore that]). Fedora spec files for such Perl module packages generally say something like "GPL or Artistic", even though Fedora classifies the Artistic License as a "bad" license. I *think* there may be other examples, not involving Perl modules or the Artistic License, where the code is dual licensed under a good license and a bad license and the spec file only gives the good license. The only rationale I could come up with for the difference in approach is that the Artistic License, while "bad" from Fedora's perspective, is generally seen as plausibly-FOSS (it's an OSI-approved license, for one thing). I think it comes down to whether Fedora wants to have spec files that say, for example, "GPL or Proprietary" much as it has spec files that say "GPL or Artistic".
It's true there is inconsistency regarding the License tag in the spec file. As the package maintainer and as part of the Fedora project, I would prefer that the License tag in the spec reflect the license terms that we are distributing the built package against. So in the case of Perl modules that are generally GPL or Artistic, the Fedora project is really redistributing them under the terms of the GPL only, right? Does it follow that we [Fedora] take an open source project that is dual licensed and use the license that is acceptable in our project and redistribute under those terms? Is that even a thing one can do? Given the "or" usage, my assumption is yes. The author is giving the downstream user the choice of using that work under the terms of the GPL or the terms of the Artistic license. In the case of Fedora, we've deemed Artistic undesirable which means our use of the modules is technically under the terms of the GPL. For me, I would prefer to see this reflected in the License tags in spec files so we can see how we're integrating components in to Fedora. If we note a license that we can't use or that we are not using, it makes it harder to see at a glance _what_ terms actually apply to that component. And that makes it harder for other packagers looking for license-compatible dependencies. I realize this is yet another work project and also that I may be incorrect regarding what we can and can't do with regard to dual-licensed projects. If we are unable to say "we're using the Perl modules under the terms of the GPL" and exclude the Artistic license, then really the "or" boolean doesn't apply and it's really always "and". So many licenses, so many questions.... -- David Cantrell <dcantrell@xxxxxxxxxx> Red Hat, Inc. | Boston, MA | EST5EDT _______________________________________________ legal mailing list -- legal@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to legal-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/legal@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
