Extended abstract presented at the CRIS2022 conference in Dubrovnik.-- Event programme available at https://cris2022.srce.hr/#section-program ; 16 slides.-- Presentation delivered within the session "Open Science implementation [II]" ; In 2020, the Luxembourg National Research Fund (FNR), the National Library of Luxembourg (BnL), and ChronosHub joined forces and embarked on a collaborative journey to help address and resolve challenges emerging from OA developments in the research ecosystem. In 2017, FNR introduced its first Open Access Policy and created an Open Access Fund to contribute to APC costs for publications resulting from FNR funded research. The administrative burden for FNR and institutions in general was prominent, causing a lot of painful processes that impacted the entire workflow. Prompted to find a solution to enhance and improve the infrastructure and address these challenges, FNR and BnL entered a pilot with ChronosHub, a platform that offers a 360-degree approach to OA Management. Now, FNR, BnL, and ChronosHub have moved on to sign a long-term operational agreement to streamline OA management on a national level which ties in all research institutions in the country. Luxembourg now has a systematic approach to drive Open Access, FAIR data, and Open Science and the partnership between ChronosHub and Luxembourg has helped optimize the interplay and the communication between FNR, publishers, institutions, and authors.
