Subject [jira] [Commented] (LEGAL-362) Supposed GPLv3 non-derivative work in sub-sub-dependency Apache Airflow
Date Sat, 03 Feb 2018 16:14:02 GMT

    [ https://issues.apache.org/jira/browse/LEGAL-362?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16351436#comment-16351436

Bolke de Bruin commented on LEGAL-362:

It is a runtime dependency. So we don't distribute 'unidecode' ourselves and the original
is obtained from its official distribution channel when installing by the package manager
(pip / anaconda).

> 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
> 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 that they are not to be considered a derivative of unidecide.
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.
