Re: Licence question: using AGPL and Odoo proprietary modules on the same server

OCA should veil for the open source part of Odoo (https://odoo-community.org/about). Encouraging to use LGPL only favors the closed source part of the ecosystem, as you can mount on top OCA LGPL modules any private module, so people will only provide to/improve OCA base tools, while keeping by themselves the finished business solutions as private. That's why if we relicense even these base tools to LGPL, the real value provided by OCA will go down, only getting base/tool modules that are not finished business solutions. That's why we should force people to play with the same open source rules. And the tool for that is AGPL. Imagine if my company Tecnativa would retain their RMA, HR shift, resource booking, etc complete apps as private because technically they don't depend on AGPL code, what would OCA be without them?

And this is not something that each individual should investigate, OCA should invest resources in assuring that there's no problem in this, and as this sometimes requires an initial jurisprudence case, to assure that if that case comes one day, OCA will provide the legal assistance. If none of these things happen, OCA would fail in its mission IMO.

Regards.

  • Licence question: using AGPL and Odoo proprietary modules on the same server
    Hi,

    After years of only working on Odoo community, we are starting to have several enterprise clients.

    The OCA website at https://odoo-community.org/resources/faq indicates:

    Can I run OCA AGPL modules and closed source modules on the same instance?
    Yes, as long as closed source modules do not depend on AGPL ones and respect the license of its dependencies defined in the “depends” key of its manifest file (and vice versa).


    Will we be able to use AGPL modules and paid ones?

    Odoo projects will be able to use AGPL modules or paid modules under proprietary licenses, but it is not possible to combine both. Combining LGLPv3 modules and proprietary modules is fine however, so we encourage current owners licensing under AGPL to move to LGPLv3 too, in order to avoid complications for end users.

    My CEO believes that this using both AGPL and proprietary modules, even if they do not have dependencies, is not allowed by the AGPL license.
    I’ve searched a bit on the mailing list (that started in 2015) but I have not found no discussion on the subject.
    On what basis does the OCA position comes from?
