Hi all,
I'm thinking about wrapping up ExtJS (a JavaScript framework, http://extjs.com) for TurboGears and wondered if the license conditions are okay for it to be included in Fedora. Note that there are two stable versions, v1.1 and v2.0, which are partly incompatible and there is code that won't work with the newer one.
Basically it sounds to me like "LGPLv3 for the JavaScript code, other assets (graphics, style sheets) may only be shipped with these components" which seems to be what we allow for e.g. games where artwork often has a restrictive license, but anyway here are the relevant bits from LICENSE.txt in the relevant ZIP archive:
--- 8< --- ExtJS v1.1.1 ------- http://extjs.com/license
The CSS and Graphics ("Assets") distributed with Ext are licensed for use ONLY with their associated Ext JavaScript component ("Component"). Use of the Assets in any way that does not also include the Component is prohibited without explicit permission from Ext JS, LLC. Deriving images and CSS from the Assets in an effort to bypass this license is also prohibited.

Ping -- does anyone have an opinion on the following issue?

IMO, this is completely unacceptable unless we have a free "assets" set that can replace this.

Hmm, I wonder why shipping uqm-content is acceptable then, see /usr/share/doc/uqm-0.6.2:

I agree that CC-BY-NC-SA is slightly less restrictive than the extjs assets license above, but where do we (in our licensing guidelines) make that distinction?

You should file a bug report. This isn't allowed either.

Looks like this is even murkier.
