Open meets Geo: DCAT-AP schema plugin for GeoNetwork
Informatie Vlaanderen and GIM have developed a DCAT-AP schema plugin for GeoNetwork. The schema plugin is based on an encoding of DCAT-AP v1.1 in RDF/XML syntax. It includes the following features: an enhanced editor, a DCAT-AP RDF harvester, an enhanced RDF endpoint with LDP paging, and an HTML and PDF view of DCAT-AP records. Whereas GeoNetwork was previously mostly used for maintaining metadata about geographical datasets in the ISO19139 standard, this plugin makes it possible to also maintain records in GeoNetwork using the DCAT-AP standard, which is commonly used for describing open government data. Additionally, the schema plugin makes it possible to bi-directionally convert metadata from one standard into the other. Finally, the harvester and RDF endpoint facilitate a better exchange of metadata between GeoNetwork and other open-data platforms such as CKAN or TheDataTank. The plugin will be released under the GPLv2 license by October 2018.
