Hello all

I'm Martin Desruisseaux, a former GeoTools 2 contributor and now a 
developer of the Geotoolkit.org project (http://www.geotoolkit.org).

In our search for a community, we had a recent discussion with members 
of the Apache Spatial Information System project 
(http://incubator.apache.org/sis/), which is in incubation. A small 
email exchange gave me the feeling that our design goals could be in 
phase. We would like to offer them the Geotoolkit.org code. In order to 
make that possible, we need OSGeo permission to re-license 
Geotoolkit.org from its current LGPL 2.1 license to the more permissive 
Apache license. The proposal is not to transfer the totality of 
Geotoolkit.org to Apache SIS, but to allow them to review the code and 
pick-up whatever they wish on a case-by-case basis. The transition to 
Apache SIS would probably be slow and very progressive.

Geotoolkit.org is a fork of GeoTools 2.6 followed by 4 years of 
developments. The project contains two parts: "core" and "pending". Our 
proposal is to begin with the "core" part, which include material 
derived from the following GeoTools 2.6 modules:

   * utilities
   * metadata
   * referencing
   * core of coverage (excluding I/O)
   * many (but not all) Swing widgets

In 2008 those modules were written (according SVN history) at 95% by 
myself, Geomatys or IRD institute. The remaining 5% were written by 
other GeoTools contributors. To my knowledge, everyone signed the 
copyright assignment on http://download.osgeo.org/osgeo/legal/ which 
grants copyright to OSGeo. However because the GeoTools community may 
have vested interest in this re-licensing decision, I wish to ask on 
this mailing list.

I would like to emphases that this is not a demand for relicensing 
current GeoTools, but only relicensing of the GeoTools 2.6 code from 
which "Geotidy" (the Geotoolkit.org precursor) is derived, which is 4 
years old. If the community accepts to grant us the permission to 
relicense 100% of Geotoolkit.org "core", that would be truly 
appreciated. But in case of objection, we are willing to rewrite the 5% 
of "core" code which was not written by myself, Geomatys or IRD.

It the community accepts re-licensing, this would allows Apache SIS to 
gain services they are currently missing, allows Geotoolkit.org code 
base to gain a community, and possibly allows the GeoTools project to 
gain a metadata and referencing library maintained by a trusted 
foundation, which could complete or replace the current referencing 
module as GeoTools wish. The Geotk referencing module got 4 years of 
extensive development since our departure, and has capabilities which 
are - to my knowledge - unique in the open source world.

     Regards,

         Martin Desruisseaux
