The document outlines a plan called Plan4Business that aims to establish platforms for open and commercial data sharing to enable sustainable business practices. It proposes an "onion model" with an open data platform at the core that is separated from commercial repositories and services. The open platform would make data more accessible for communities and not dependent on any single commercial entity. It describes policies for data ownership, licensing, and interoperability on the open platform. Revenue models are suggested for maintaining both platforms, including contributions, future project funding, advertising, and cost-sharing partnerships. The goal is to eventually expand commercially across Europe and beyond while building a large community around the open data resources.
