The EOV Metadata Submission Application is designed to streamline the creation of metadata JSON-LD files and sitemaps for data producers (e.g. programmes, projects, and/or institutions) that monitor Essential Ocean Variables (EOV). This tool is intended to facilitate integration with the GOOS BioEco Portal and the Ocean Data and Information System (ODIS). Generated JSON-LD files are submitted to the BioEcoOcean GitHub repository as issues, when entries are updated, a date is added in a comment. A sitemap is produced of all entries which is connected to the ODIS Catalogue.
