Subject [jira] [Commented] (LEGAL-173) Using Virtuoso GPL2 JDBC driver in one of the Apache Clerezza (optional) components

Lawrence Rosen commented on LEGAL-173:


I'm glad we're focusing on the underlying issue here. You wrote:

Where in Apache policy does it say that libraries our software uses have to be changeable,
or even open source? Even Richard Stallman realized from the beginning of the free software
movement that there are non-free dependencies we have to make use of -- at least until there
is an open source version of that software that meets our needs. For example, we're using
GPL dictionaries in our Open Office product without adverse consequences! We design our software
to link to proprietary software without adverse consequences! 

Is our distribution of unmodified, non-Apache (albeit "open source") software always counter
to Apache policy, even if it helps us and our users?

We are being given permission to use the JDBC driver without changes, and we don't want to
change it. Furthermore, we're being given assurances that we (and our downstream users) can
do exactly the same thing without any adverse affects on our (or their) other software.

I recognize that we are free to define our policy as you tried paraphrased it. But if we do
that, let's please debate the consequences of saying that "GPL+exception" is the same as "GPL"
merely because that "exception" doesn't apply if we modify the library (which we won't do

particular case Virtuoso has the following exemption in one of its license files (https://github.com/openlink/virtuoso-opensource/blob/develop/6/LICENSE):
