Open access to scientific data: excerpts from the INSU prospective

Data is at the heart of the scientific method at INSU, the French national institute for Universe Sciences. INSU disciplines were engaged in data sharing and data management long before political acceptance to Open Science and the definition of FAIR principles (Findable, Accessible, Interoperable, Reusable). This early involvement brought us to the leading edge of data sharing. Open access to scientific data was therefore a natural topic for the first INSU inter-displinary prospective organized in 2019-2020. The discussion was organized on different points: the FAIR context, scientific data management and services, data models and metadata standardisation, and the certification of data repositories (CoreTrustSeal). The current paper provides an excerpt from the discussions, conclusions and recommendations, with an intended bias toward astronomy and astrophysics. The aim is to trigger interest and give extra motivation to read the full online document with the conclusions from the prospective on open access to scientific data.
