I'm following this list since the recent exchanges about re-lisensing and wanted to speak about Justin's comments on Arnulf e-mail.
I wanted to clarify some points about contributions done by people (and more precisely by Justin) under Martin's "authority".
I asked Martin about it and here's his answer :
- About Justin's contribution, we know that he wrote the NewZealandMapGrid projection. He has always been cited as the first author of that class  and we never had the intention to re-license it. See also the Mercurial history for those who want to be sure that we didn't changed the author ordering.
- Other Justin's contributions (URN factory, String <-> Number converters) can easily be delegated to Apache SIS contributors. Again, Justin has always been cited as the first author of those classes (, ).
- We have always recognized the other contributions straight in the javadoc home page .
 http://www.geotoolkit.org/apidocs/overview-summary.html - see "Authors" close to the bottom
An other important thing to note : for every GeoTools-derived classes ported to SIS, we intend to publish a web page with the full history, highlight on commits of other contributors and an explanation about how those contribution has been omitted or fully rewritten. Anyone will be able to verify by himself.
I hope you will be reassured by this, but please be aware that it is easy to verify the historical contributions of everyone, looking at the Geotools SVN logs and compare it to our Mercurial repository, which of course is freely accessible.
All the best,
