EOSC Federation: Architecture and Federating Capabilities

This concept paper describes fundamental concepts to enable the Federation of EOSC Nodes, especially technical aspects, and defines key terms. It presents the EOSC Federation Architecture and introduces the concepts of EOSC Federating Capabilities describing how the Nodes of the Federation should interact to deliver them jointly. To enhance and fine-tune the paper, we also launched a survey to gather community feedback. The survey was available until 29 November 2024, and an updated version of the document will be presented by Q2 2025.
