Using geo dcat ap specification for sharing metadata in geoss and inspire

The document discusses using the GeoDCAT-AP specification for sharing metadata in the Global Earth Observation System of Systems (GEOSS) and the INSPIRE Directive. It describes the Czech Republic's implementation of a national INSPIRE geoportal that harvests metadata from various catalogues using the Common Warehouse Metamodel and publishes the metadata using GeoDCAT-AP to be discoverable on the European INSPIRE geoportal and other systems. The national geoportal extends the Catalogue Service for the Web to support additional standards like ISO 19139 and allows metadata to be harvested from sources like the Czech National Open Data Catalogue using its API or the DCAT-AP format.
