[postgis-users] The first release of the PostGIS Add-ons is out!

[Mathieu Basille]

Sorry to be a little bit late in the discussion, but in my opinion, there 
are really two sensible solutions:

1) Use the most simple and liberal (permissive) license. No license is not 
an option, since it means copyright by default, and public domain is not a 
good option due to specific issues in some countries. With this approach, 
the BSD is probably the best choice: the license is very short, and very 
easy to read and understand. This would basically allow anybody to reuse 
parts or whole of the code in open source or proprietary projects.

2) Stick to the PostGIS license as you suggest. This can be justified by 
the fact that the code would be hard to reuse without PostGIS itself, so 
that it's not such a big deal to restrict the reuse of the code... As the 
others said, if you're more comfortable with it, stick to it! However, keep 
in mind, that, if you have many contributions, it would make a latter 
change to a more liberal license all the more difficult (every other 
authors would have to give his agreement). This doesn't make it a bad 
choice, though, but it's better to know the pros and cons in advance!
