Government — entry 009 of 90
City, Berlin
Berlin's open-data frontend at daten.berlin.de runs on Drupal, but that's only half the picture: the frontend's own page settings name a backing CKAN instance, datenregister.berlin.de, and a live keyless GET against its /api/3/action/package_search endpoint returns full JSON metadata for more than 2,600 datasets. Neither that response nor an OPTIONS preflight carries an Access-Control-Allow-Origin header, so cross-origin reads are blocked. Dataset resources are still published as JSON, WMS, and WFS files across various berlin.de subdomains, and everything stays keyless over HTTPS.
