while creating a Debian package from LDView I ran into trouble regarding the copyright of LDView and its included components. It is hard to gather the required information as most files included in LDView lack a copyright statement at the beginning of the file. Here are my more specific questions:
http://ldview.sourceforge.net/ states "LDView and this web page are both Copyright © 2009 Travis Cobbs". This conflicts with "some" files which claim that LDView is copyright of "Travis Cobbs & Peter Bartfai". On the other hand there are directories like LDExporter which contain only one hint of the copyright holder. In LDExporter/LDExporter.cpp it says "m_appCopyright("Copyright (C) 2008 Travis Cobbs")". So is LDExporter and its content by Travis Cobbs only or by Travis Cobbs AND Peter Bartfai? It is released under the GPL2 as well?
The LDLoader subdirectory seems to all be by "Lars C. Hassing"? There are only four files which say so. Are there exceptions which are not by him?
The LDLib, TRE and QT directories contains no C++ source file at all which tells who has the copyright. In fact the files which do contain copyright information are translation files and not sourcecode files. So maybe they are all GPL2. Are they? And even if they are: who is the author of the source code in those directories?
Then there is the TCFoundation directory. The only two files in it which state copyright information are ConvertUTF.c and ConvertUTF.h which are by "Unicode, Inc.". What about the rest? Is TCFoundation part of another project? Who is the author?
The there are all the resources like images and models. They probably GPL too? Who is their author?
Can you please clarify the situation? It would be nice if you either add a copyright notice at the top of each file or one file which explains the situation. It would further help if you add at least the years for which authors hold copyright over each file? It seems that Travis Cobbs is having copyright over most files since 2000 and Peter Bartfai only joined in 2009?
