I am releasing a new open source project that uses ExtJS 2.2. My project is released under the ASL v 2.0 license, which I understand to be compatible with GPL v 3.0. The question I have is, should I provide a notice about the Ext licensing terms in the project notes to make clear that Ext provides commercial licensing terms for commercial projects? Just want to make sure I am doing the right by the Ext licenseing terms....

Thanks,

Rob

Hi Rob,

What is usually implied regarding the ASLv2 being "compatible" with the GPL is the ability to distribute ASL code within a GPL project (not the other way around). In many cases, if code from a GPL project is incorporated into an ASL project, the project must now be GPL.

Ext has addressed the ability for permissive open source projects (like your own) to release code under the ASF, while using Ext JS under the GPL, without requiring the entire project be GPL'ed by using a FLOSS Exception/Extention.

For open source projects that are not distributed under the GPL v3 license, the following FLOSS exceptions are available:





Open Source License Exception for Applications (http://extjs.com/forum/../products/floss-exception.php)
Open Source License Exception for Development (http://extjs.com/forum/../products/ux-exception.php)



You would need to distribute the FLOSS Exception language with the GPL, and indicate you are using one of the above FLOSS Exceptions to release your code under the ASL.

Hope that helps.
