[jira] [Commented] (LEGAL-362) Supposed GPLv3 non-derivative work
in sub-sub-dependency Apache Airflow
[ https://issues.apache.org/jira/browse/LEGAL-362?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16340815#comment-16340815 ]
Justin Mclean commented on LEGAL-362:
-------------------------------------
IANAL but looks like existing ASF policy would consider it a derivative work. See [https://www.apache.org/licenses/GPL-compatibility.html] where it states:
"We avoid GPLv3 software because merely linking to it is considered by the GPLv3 authors to create a derivative work." and "This is an identical issue for both GPLv2 and GPLv3."

> Project: Legal Discuss
> Issue Type: Question
> Reporter: Bolke de Bruin
> Priority: Major
>
> Hello,
> Apache Airflow (incubating) is dependent on python-nvd3 (BSD) > python-slugify (MIT) > unidecode (GPLv2 and later) by means of importing python-nvd3 as a module. We were made aware of this in AIRFLOW-1430 .--
> As 'unidecode' is a derivative work of a Perl module that was dual licensed Perl Artistic and GPLv2 and later, I initially asked the author to consider dual licensing again. This was [denied|https://github.com/avian2/unidecode/issues/23#issuecomment-360242600].
> Reaching out to the authors of python-slugify I asked them to consider basing on an alternative module citing their MIT license might be in violation of the GPLv2+ licensed module. Again this was denied, [citing|https://github.com/un33k/python-slugify/issues/50#issuecomment-360258528] that they did not consider themselves derivative work of unidecode.
> I reached out again to the author of unidecode, asking if he agrees with the views of the authors of python-slugify. He [does|https://github.com/avian2/unidecode/issues/23#issuecomment-360242600].
> So, I'm inclined to argue that given the author of unidecode does not consider python-slugify is a derivative work of his own work that there is no license violation, but I wonder what your views are.
