Now PostGIS is licensed under the GPL and I wonder if we can use it
in a commercial (customer specific) project then. The source code
will not be made open source, but of course the customer will get
the source code.
Is it still OK to use the GPL licensed PostGIS in this case? Is
that then considered a derivative work because the application will
not work without PostGIS?
If it's pure GPL, then postgresql is automagically relicenced to GPL,
because postgresql allows relicencing and GPL force it to be GPL.
Your source code must be in GPL too. Remember, it's a virus licence
and has the same problem that Midas king had.
Thanks for the answer.
I think we'll better be safe than sorry and we will not use PostGIS then.
It doesn't mean, so you must to publish your source code on net. Your
codes have to be available to your customers. That is all. You can
distribute your product as service, and then you don't need to show
your codes.
I am developing a web system that uses postgres and postgis, my source
code is released under Apache2 licence (The customers has a copy of the
whole source reposotory). The server interacts using jdbc and a C
function for postgres. The client (java) interacts only with my server
application.
I think that this is safe, I'm doing wrong?
My software has to use the GPL? if I can I'd like to use Apache2
licence for my source code.

Edoardo
