FAIR-IMPACT works towards improving the FAIRness of data and other research outputs by coordinating the implementation of frameworks and the alignment of FAIR data practices. It identifies practices, policies, tools and technical specifications to guide its target stakeholders towards a FAIR data management cycle. It focuses on a) persistent identifiers (PIDs), b) metadata and ontologies, c) metrics, certification and guidelines, d) interoperability. The expected impacts related to these pillars of FAIR-IMPACT are a) a coherent implementation of PIDs across the EOSC, b) improved interoperability of federated research objects across the EOSC enabled by better governance of FAIR semantic artefacts and clear, common ways to interact with metadata and ontologies, c) adapted guidelines and frameworks for creating and assessing the FAIRness of data, research software, semantic artefacts and the trustworthiness of repositories that curate them as Trustworthy Digital Repositories (TDRs), d) increased data accessibility for researchers and other European data users and stakeholders. FAIR-IMPACT supports wide uptake of and compliance with FAIR data principles and practices by national and European research data and metadata providers and repositories, leading to the development of a Web of FAIR data and related services. Active, engaged and informed research communities supporting the implementation of an operational, open and FAIR EOSC ecosystem through increased uptake and adoption at cross-domain and pan-European level is of high significance. Adoption and implementation are supported by open calls for funding, in-kind contributions and harmonisation efforts. A High Level Advisory Committee advises at strategic level and 13 EOSC FAIR Champions act as ambassadors in their respective communities. FAIR-IMPACT operates at national, European and institutional levels addressing a wide range of stakeholders, providing extra support to research performing organisations, repositories and data service providers, and national initiatives. Integrated real-life use cases in social sciences and humanities, photon and neutron sciences, life sciences and agri-food and environmental sciences bring expertise and solutions and act as a bridge to their communities. FAIR-IMPACT contributes to the Horizon Europe EOSC Partnership in line with specific action areas of the EOSC Strategic Research and Innovation Agenda. The Technical Bridging Team, Synchronisation Force, and FAIR Implementation Team constitute clear and functioning mechanisms for supporting the governance, coordination, and collaboration activities carried out by the EOSC Partnership.
