A common information system (Theia/OZCAR IS) was built to make theirin situobservation FAIR (findable, accessible, interoperable, reusable). The IS architecture was designed after consultation of the users, data producers and IT teams involved in data management. A common data model based on various metadata standards was defined to create information fluxes between observatories' ISs and the Theia/OZCAR IS. Controlled vocabularies were defined to develop a data discovery web portal offering a faceted search with various criteria, including variables names and categories that were harmonized in a thesaurus published on the web. This paper describes the IS architecture, the pivot data model and open-source solutions used to implement data discovery, and future steps to implement data downloading and interoperability services. specialized data portal FAIR data OZCAR-RI information system land surface critical zone in situ observations FRANCE 062 021 020 124 Hydrological Sciences Journal = Journal des Sciences Hydrologiques 67 16 2401-2419 2022 0262-6667 https://www.documentation.ird.fr/hor/fdi:010079116 10.1080/02626667.2020.1764568 0262-6667 [F B010079116] https://www.documentation.ird.fr/hor/fdi:010079116 https://www.documentation.ird.fr/intranet/publi/2020/07/010079116.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2020-07-31 2025-02-24 fdi:010079116 fre
