Your answer is in the licensing FAQ (http://plone.org/foundation/copyrights/license-faq): *Must add-on products for Plone be licensed under the GPL?* In most cases, yes. The GPL covers any "derivative works" of Plone, and defines these derivative works as those which: * copy or modify the code we provide to you (this includes Python code, HTML, images, etc.) * links to our GPL'd Python code (eg, by using Python's "import" statement) The vast majority of add-on products exhibit one or both of these behaviors, and, as such, must be licensed under the GPL. It is possible to create an add-on product that does not exhibit these behaviors (many generic Zope products that are not specific to Plone, and some Plone themes, do not). Such products need not be licensed under the GPL. *Must theme products for Plone be licensed under the GPL?* Yes, if the theme product imports from GPL-licensed code. See the Plone Theme License Policy <http://plone.org/foundation/materials/foundation-resolutions/plone-framework-components-relicensing-policy> for more information. > Does that prevent you from being to sell a plugin and not publish the plugin > on pypi or plone.org? The GPL allow you to sell any product on the condition you share modifications with your customers. You must mention in the documentation the original work and you can publish your own version (call it a branch or a fork, as you prefer) where you want. It can be your own pypi server. Publication management on pypi and on plone.org with the same name can be complicated if the original author doesn't want to give you rights, or if he disappeared. Renaming is allowed. -- Encolpe DEGOUTE http://encolpe.degoute.free.fr/ Logiciels libres, hockey sur glace et autres activités cérébrales _______________________________________________ Product-Developers mailing list product-develop...@lists.plone.org https://lists.plone.org/mailman/listinfo/plone-product-developers
