Berlin Open Data Search: Datasets by Keyword, Publisher and Licence

berlinopendata/search-datasets

Searches the Berlin open data register (datenregister.berlin.de) for datasets matching your search terms and returns the total match count plus, for each dataset on the requested page, its title, description, publisher, declared licence, tags, resources and download links. Catalogue records only, not the data files; text is German. Data of Land Berlin publishers, each under its own declared licence, served by Eden Engine; not an official Land Berlin product.
