[mkgmap-dev] splitter license & copyright

Sat Jan 10 06:17:00 GMT 2015

Hi Bas, hi Steve,

I must confess that I don't care about the licence as long
as I am the author. I'd be happy to hear that someone else
can use a copy of my work, also if it is for commercial purposes.
If I code an algo that is described somewhere I try to point out the source,
and I avoid to copy copyrighted sources as I am not able
to understand lawyers speach (neither in English nor in German).

I do not want to put my full name
into the sources because I don't like to find myself with search engines like
Google, so I use GerdP instead. 
If that is a problem this can be changed, but I'd prefer something like
"Copyright (C) 20xx by the splitter contributors"
if we have to state a copyright at all.

Hi all,

To follow up on my previous email regarding licensing of Osmosis
portions included in the splitter source, there are a few issues with
the splitter source itself too.

Almost none of the splitter source files declare the author beside the
copyright year. All files only declare the copyright year, except:

src/uk/me/parabola/splitter/UnknownFeatureException.java:
 * Copyright (C) 2011 by the splitter contributors

src/uk/me/parabola/splitter/Version.java:
 * Copyright (C) 2007 Steve Ratcliffe

The mkgmap source has this issue too, but to a much lesser extend. Most
of those files declare the year and Steve as the author.

Based on the svn log of the files which only declare the copyright year,
the authors should be as in the attrached splitter-copyright.patch.

For each file the the author of the first SVN revision was assumed to
also be the author of the source file. This may be false assumption when
files are renamed, refactored, or committed by someone else. The svn
usernames were mapped to the authors of related emails to the mkgmap-dev
list.

A second issue with the splitter source files are is that some are
lacking a license header, and Version.java being licensed under the
GPL-2 only instead of "GPL-2 or GPL-3", or just GPL-3, which is
inconsistent with doc/LICENSE.readme that places the code of the project
under the GPL-3.

The splitter.licenses attachment documents the license for each of the
splitter source files.

The splitter-license.patch adds the missing license headers using GPL-3
and the copyright year and author based on the svn log like the
copyright patch. It has the same caveat as the copyright patch, the
first svn committer may not always be the copyright holder of the file
in question.

The splitter-license.patch also bumps the GPL version from 2 to 3 for
Version.java. Using "GPL-2 or GPL-3" like Gerd does for many of his
contributions may be more suitable.

Because the GPL license headers don't include the "or (at your option)
any later version" option, the copyright holders of the unlicensed and
GPL-2 licensed files need to agree with relicensing their contributions
under the GPL-3.

Kind Regards,

Bas
