Résumé
This presentation focuses on observation data management, with the example of data management in the OSU OREME observatory (http://oreme.org).French observatories are in charge of the data of national observation services (SNO). They deal with diverse type of data, that they have to structure, describe, reference, identify, and disseminate, by respecting FAIR principles: data should be findable, accessible, interoprable and reusable.This presentation describes the methods used at OREME to achieve these aims.
