Re: Advice regarding chess engine database files license

 The chess tablebase files are generated by the Gaviota Engine whose
 license is clearly not DFSG compatible. However, the author is
 releasing the generated database files under the MIT license. Is the
 MIT license for these database files DFSG compatible?  [...]

Yes, MIT/X11 is DFSG-compatible and http://www.debian.org/legal/licenses
says similar licences are already in the archive.

The Gaviota Engine licence shouldn't apply to the database files. See
http://www.gnu.org/licenses/gpl-faq.html#GPLOutput for a similar topic.

Thanks for asking,

Sounds like they should go to contrib though, due to the non-free build-dep?

If the database files need to be built by the Gaviota Engine, I think.
I don't know it well enough to say.

Hope that helps,

Some small database (compressed) files are included in the upstream sources
and other larger ones can be downloaded from this site:
http://www.olympuschess.com/egtb/gaviota/

So, if we can consider these database files as output files, then I think
these are good to go to main. However, if these should be treated as
binary files which must be generated from the Gaviota Engine, then these
should go to contrib. Can I assume the former and upload these to main?

Thanks,
Varun

MIT code embedded into GPL-3+ library

2013-06-05 Thread Ondřej Surý
Hi,

I am working on packaging ccnet[1] library (requirement for seafile), and the 
upstream code has two licenses in the base directory - MIT and GPL-3+.

When I asked for clarification they have replied the code is GPL-3+ with some 
parts reused from some other project which was MIT licensed.

Unfortunatelly the individual source files are not licensed, so it's unclear to 
me what's the license of the files and the packages as whole.

Can you provide a guidance?

(It would still need openssl+gpl exception to go in.)
