Résumé
The document presents the method used at OSU OREME observatory to harvest a standardized metadata GeoNetwork 3 catalogue by the Open platform for French public data data.gouv.fr.The harvesting process is based on DCAT standard. Some corrections and improvements are necessary to achieve the harvesting by data.gouv.fr. First, the GeoNetwork DCAT conversion has to be modified: change its configuration, fix some conversion errors, and adapt the conversion for data.gouv.fr. Then, recommandations have to be followed for metadata furniture.This communication provides a detailed process to allow metadata to be displayed in the national data platform.
