Comment(by SimonKing):
I am about to produce a version 1.0.1, that will essentially be an attempt
to fix the licence.
- I took the COPYING file from the MeatAxe 2.2.4 and put it on top of our
modified MeatAxe version. Since the licence allows redistribution of the
modified work, as long as the COPYING file isn't touched, this should be
alright.
- The C-code of David Green got a similar COPYING file. So, this is GPL
2+ as well.
- Each of my files starts with a header, referring to the GPL, version 2
or later.
- I think it should be appropriate to put the data bases under a Creative
Commons Attribution-Share Alike licence.
__Questions:__
- In order to put the data bases under the mentioned licence, does it
suffice to state it in the documentation, as I now did in
http://sage.math.washington.edu/home/SimonKing/Cohomology/#licence ? You
suggested to put a 'LICENSE.txt' into the package; but the major part of
the data base is not included in the package, but only available in the
internet. So, I thought that the package documentation is the right place
for stating the licence. Is this OK? Or perhaps I should add some words
concerning the data bases in the file 'SPKG.txt', that has a licence
section anyway?
- It is also stated that the documentation itself is under CC
Attribution-Share Alike. But: The documentation is mainly auto-generated
using the source code of our package, which means that the documentation
is derived work from something that is under GPL 2+. So, is it legal to
use another licence for the documentation, or am I shooting myself in the
foot?
Once theses questions are addressed, I will put a version 1.0.1 of our
package online, so that hopefully the last reviewing steps can be done.
Best regards,
Simon
