[xwiki-users] LGPL w/r/t plugins - are they derivative?

[Catalin Hritcu]

Hi Apperson,

My advice is to read this:
http://www.gnu.org/licenses/lgpl.html
and the relevant entries here:
http://www.gnu.org/licenses/gpl-faq.html
or consult a copyright lawyer.

IANAL, but to me this might very well be a border case, so it depends
very much how your plugin interfaces with XWiki. With the current
plugin architecture you will quite likely have to modify XWiki in
order to interface with it, so at least this interface code will have
to be LGPL. In the near future it is very likely that plugins will be
a completely separate components using XWiki services, but this is
unfortunately not the case at this time.
