The document discusses the EOSC-hub project, which aims to create an integration and management system called "the Hub" for the future European Open Science Cloud (EOSC). The Hub will engage providers from major European digital infrastructures to offer services, software, and data for advanced research. EOSC-hub will integrate production-ready services, operate and provide access to resources, and support the utilization of resources for open science, open innovation, and being open to the world. It will support the EOSC Declaration by providing a service integrator and federator for the EOSC and developing expertise in procuring digital services.
