The Eclipse Foundation (EF) is a 17 years old non-profit organization with legal jurisdiction in the European Union that was... "Created to allow a vendor-neutral, open, and transparent community to be established around the original Eclipse Project, the Foundation provides a global community of individuals and organizations with a mature, scalable, and commercially focused environment for collaboration and innovation. Its stated aim is to cultivate both the community and "an ecosystem of complementary products and services." [1] Eclipse Foundation currently hosts +450 Open Source projects and 18 different ecosystems of organizations, called Working Groups, having a total of +320 Member organizations. This talk will describe the structure that these community driven projects and Working Groups have unique approach that the Eclipse Foundation have as well as how the Working Groups support the Open Source projects. It will also describe the relation between these two different entities and how the Eclipse Foundation guarantees that community driven projects do not become pay-to-play environments. Through examples, Wayne Beaton will analyse the successes and challenges of this set up as well as some of the most relevant lessons learnt through these years of relation between these two Governance structures.
