The EU-funded RELIANCE project seeks to extend the EOSC's capabilities with an enhanced support for various research activities, aligned with the EOSC Interoperability Framework. It will boost the discovery of and access to research data, including Copernicus data, improve the extraction of relevant information, and manage the research lifecycle via research objects while promoting FAIR and open science principles. By adopting a holistic research management approach, the project aims to enhance support for multidisciplinary research, particularly in Earth Science, improving European science as a whole.
