Résumé
The French program OneWater - Eau Bien Commun (2022-2032) aims to better manage water as a common good. It generates a wide range of data (scientific, social, models) that are not yet in line with FAIR principles.To remedy this, a national FAIR platform is currently being developed. It aims to create an ecosystem of interoperable data, beyond a simple catalog, based on international standards and national and global collaborations.Three axes are being developed:1 -A survey to identify needs and build the platform with users.2- An adaptation of FAIR principles to the water sector, with grids tested on existing data.3 - A technical architecture in line with recent standards (OGC, W3C, etc.) incorporating FAIR best practices.The project reinforces access, sharing and reuse of water-related data.
