Thank for the info. I knew that the FSF endorses a number of different
licenses, but I was under the impression that the only projects for
which copyright transfer was in place were under the GPL or LGPL
license. I don't know if it makes much sense for other, more
permissive, licenses.

Indeed. I believe going the burden of copyright transfer makes sense
only for major projects under copyleft licenses.
Cheers,
Daniele

Hi Daniele,
First off, the FSF uses and endorses a number of non GPL licenses. They
reccomend the Apache license over MIT-style licenses for permissive cases
due to patent issues, but they don't require it. In fact, even the GNU
project has several X11 (the FSF's name for the MIT license) licensed
projects (e.g. Off the top of my head, I know ncurses is both an official
GNU project and is X11-licensed.).
However, I'm glad you brought this up. I haven't actually filled out a
copyright transfer form to the FSF. I intended to at one point, but never
did and didn't think about the copyright assignment in the license header
very much. Not doing so, and leaving copyright in the name of any potential
contributors actually makes things quite a bit simpler.
At any rate, it's certainly something I should clarify.
Thanks!

Hello Joe,
I accidentally had a look at the source file you linked to and I found
the copyright and license terms quite strange. Are you really
transferring copyright for your work to the Free Software Foundation
which is releasing it under the MIT license? I find very strange that
the FSF is using a license other than the (L)GPL. Does it also mean
that who wants to contribute to your project must sign a copyright
assignment to the FSF?
I'm puzzled.
Best,
Daniele

Hi Nils,
I'm glad you found it useful!
I'm certainly not opposed to seeing it integrated into matplotlib in the
long run. At the moment, though, it's probably changing a bit too
quickly. There's a lot of little things I'd like to add to it.
On the other hand, if it ever were integrated upstream, there's an
opportunity to clean things up quite a bit, as mpldatacursor currently has
quite a few workarounds for minor bugs in old versions of mpl and minor api
changes, etc.
Cheers!
