[Webical-developers] Webical License

[Mattijs H. <ma...@fu...>]

Hi all,

I wrote a little script to add a license file to the java files used in 
Webical. I want to add the license, but first we have to agree on the 
license to use.

I want to propose the GPL version 3 license and the following text at 
the start of each java file:

    /*
      *    Webical - http://www.webical.org
      *    Copyright (C) 2007 Func. Internet Integration

      *    (at your option) any later version.
      *

      *    but WITHOUT ANY WARRANTY; without even the implied warranty of

      *    along with this program.  If not, see
    <http://www.gnu.org/licenses/>.
      */


This text is the standard text for GPLv3 from the opensource website [1].

I found that a piece of code (LocalFileSystemStorage.class) used in 
Webical is licensed under the Apache 2.0 license.
I checked for compatibility and found this on the Apache website [2]:

    Is the Apache license compatible with the GPL (GNU Public License)?

     From the Free Software Foundation website:

    Apache License, Version 2.0

    This is a free software license, compatible with version 3 of the
    GPL. Please note that this license is not compatible with GPL
    version 2, because it has some requirements that are not in the
    older version. These include certain patent termination and
    indemnification provisions.


So the Apache 2.0 license is actually compatible with the GPLv3 license.

Let me know what you think of the license we should choose and the 
proposed text.

cheers,
Mattijs
