Eclipse Foundation Industry Collaborations are part of the Foundation’s broader ecosystem and operate within its membership and governance framework. Organisations must first become Eclipse Foundation members before joining a Working Group or an Interest Group. This ensures that every participant benefits from the same legal, intellectual property, governance, and community framework, creating a trusted, vendor-neutral environment for collaboration.
