I am willing to be overridden by the Foundation Board on this. Absent that, consider this an edict. :) Actually we briefly discussed this in a board meeting today, unrelated to this topic. I think the general principle of the repository should be that if you check out something, you can use it under the terms of the ZPL, and it won't pull in something with more restrictive clauses that affect your larger application. I don't think we've codified this principle anywhere yet, so perhaps we should. This is why depending on GPL-ed code should be avoided. Depending on, say, something LGPL-ed or MIT licensed would be fine. Note that I'm not speaking from any particular biased against GPL - I accept that projects use it and it's an appropriate license.

An application returning JSON data structures for consumption by the Ext libraries would hardly be a "derived work" from Ext: copyright doesn't control that kind of integration, or else we would have to forbid use of Python standard modules which provide interfaces to glibc. The GPL can't control what copyright law does not provide for. In particular, copyright allows regulation of creation and distribution of "derived works", but it does *not* allow the copyright holder to make up arbitrary definitions about what makes a given work "derived" or not: that would be up to the courts. >> Having an unambiguous FOSS license on the code has to be good news for >> those who would like to build and distribute such components. > > I don't find anything about the GPL to be unambiguous unless I read it > with the broadest, most paranoid interpretation.

The dependency is clearly on the presence / dynamic linkability of the non-ZPL code, and does not appear to create a "derived work" at all. >> We *still* can't put the ExtJS code itself into svn.zope.org, but >> perhaps we can now allow checking in ZPLed code which uses it. > > > No, we can't.

I was interested in the discussions surrounding it because of this; I'd already decided not to use it. Don't think that since they mention it's LGPL it actually *is* LGPL - it's clear their intent is different. ExtJS is not *actually* licensed under the LGPL.
