     Hello-

     I am writing on behalf of a community of developers working on a
     project that extends ExtJS (2.x) classes with mapping functionality
     from the OpenLayers library.  We have a number of questions related
     to licensing (and intellectual property) that we are hoping to get
     answers on.

     First, we have been calling our project GeoExt, and wanted to make
     sure the name was appropriate for us to use.  Below is a mockup of
     our issue tracker with a logo at the head.

     http://img.skitch.com/20090409-jksimuqt2axkrciw386bx2n3f4.png.

     Please let us know if the name and look of the logo are acceptable
     for us to use.

     Our library [1] extends Ext components and data utilities with
     mapping functionality from OpenLayers [2].  Our plan has been to
     distribute GeoExt under a BSD license and to include OpenLayers
     (with a BSDish license) in our releases.  We will provide
     instructions with our releases on obtaining Ext from extjs.com
     <http://extjs.com/>.  Our understanding is that we meet the terms of
     the Open Source License Exception for Development [3].

     We have received some questions from interested application
     developers regarding licensing of applications built with GeoExt and
     Ext.  I'll enumerate them below.  Thanks for any answers you are
     able to provide.


     1) If an application includes a script that is a minified version
of the
     Ext source and is not produced by the Ext build tools [4] (e.g.
minified
     with YUICompressor), I assume this is considered "Conveying Non-Source
     Forms" and not "Conveying Modified Source Versions" under GPL v3.  Is
     this assumption correct?

     If so, the GPL says the object code provider must also convey the
     machine-readable source.  One of the ways this can be done is to offer
     access to the source from a designated place (point 6.d).  Is it enough
     for the application provider to include a notice in the minified code
     that references the license and gives instruction to download the
source
     from Ext?  I'm assuming the application provider doesn't have to
provide
     access to anything else themselves (e.g. the tools used to minify the
     source or the source itself).


     2) A typical application would include Ext and application code that
     calls Ext methods.  The Open Source License Exception for
     Applications [5] suggests that code that is independent of the
     library may be distributed under one of the listed licenses (point
     2.a and the paragraph preceding it).  Is application code that
     relies on Ext (calls methods and accesses properties) considered
     independent and can this code be distributed under one of the listed
     licenses (assuming other terms are met)?


     Thanks for your responses.  We're excited to be using Ext and to be
     introducing developers of mapping applications to a rich new set of
     features.
