This extension is part of the plugin set for the Datenregister, the non-public CKAN instance that powers Berlin’s open data portal daten.berlin.de. It defines a dcatap_de profile that layers on top of euro_dcat_ap from ckanext-dcat, implementing the German DCAT Application Profile (DCAT-AP.DE). The extension draws on ckanext-dcatde but is separate due to different underlying CKAN schema requirements. It includes file format mappings and implements the IBlueprint interface for custom routes.
