Berlin Open Data (daten.berlin.de) is the open-data portal for Germany, covering Berlin. It runs on CKAN, an open catalogue standard used by many national governments. You can browse it directly at datenregister.berlin.de.
On Berlin Open Data (daten.berlin.de), most datasets here are clearly licensed — only a small share are undeclared. It's important to know that "no licence declared" is not the same as public-domain or free-to-use. Undeclared data carries no explicit permission to copy, adapt, or redistribute it — so reusers should treat it cautiously and check with the publisher before relying on it. Vizzie flags each dataset's licence (or its absence) so you can see this before you build.
Of the 2,514 datasets here whose licence Vizzie can identify, essentially all of them can be used commercially; 1% carry a share-alike condition, so work built on them has to be published under the same terms; 1% are non-commercial only. Attribution is required by almost every open licence — Vizzie writes the attribution line for you when you export or publish.
