Fwd: [Orekit Developers] Distribution of orekit-python "egg"

[Petrus Hyvönen <pe...@gmail.com>]

Hi JCC developers,

As this discussion could be of potential interest of others who makes python
modules using jcc I cross post it.

I am really not experienced in the licensing issues of open source, closed
source etc.

A JCC generated external java library .egg, do contain some JCC code, is
there something I need to do to ensure that the JCC license is fulfilled?

In my case the wrapped library is also in apache, so I guess it should not
be an issue to put the egg under apache?

Hi Luc,

Good to hear, I think it is good with an easy-entry to the orekit through
python.

I really don't know much about the licensing stuff.

- My work in this process is rather minimal, issuing the right command line
parameters.
- The JCC tool that I use for wrapping is under apache 2.0 license as well.
http://pypi.python.org/pypi/JCC/
- orekit and common maths library are included in the egg. (common math
assumed to be under apache as well)

Microsoft compiler has been used in the process, but as I understand this
does not affect the licensing?

Please send me the paper and I can understand it better, I am not really
clear right now what the actual content of the authorization is about.

Regards
/Petrus

As the licenses are the same can't imagine an issue here.

In the LICENSE file - or is that the NOTICE file - of your distribution, you 
should include a copy of the Apache2 license for JCC.

That being said, I am not a lawyer...

Giving attribution to Apache JCC is always appreciated, though.

Thanks !
