The NAIF project (National Approach for Interoperable repositories and Findable research results), co-funded by swissuniversities and 8 Swiss Higher Education Institutions, seeks to strengthen the visibility and interoperability of Swiss research. While institutional repositories hold valuable content, their metadata are often fragmented and heterogeneous, hence limiting the ability to track, connect, and reuse research information. This presentation specifically focuses on Track 4 of NAIF, dedicated to the enhancement of national and global academic data. The focus is on four critical dimensions: organizational data, authorship data, funding data, and open access information. Key challenges include standardizing organizational structures and units, ensuring reliable researcher identifiers, linking publications to funding, and capturing accurate open access metadata. Rather than providing ready-made solutions, the session highlights open questions and tasks that require collective effort. The goal is to identify good practices locally, scale them nationally, and explore opportunities for harmonization.
