RDW Open Data publishes 100 open datasets for Netherlands. Browse them live in Vizzie and turn any one into a map or chart.
RDW Open Data is the open-data portal for Netherlands. It runs on Socrata, Tyler Technologies' open-data platform. You can browse it directly at opendata.rdw.nl.
On RDW Open Data, a majority of datasets here declare no licence at all. 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 49 datasets here whose licence Vizzie can identify, essentially all of them can be used commercially. Attribution is required by almost every open licence — Vizzie writes the attribution line for you when you export or publish.
The Dutch vehicle authority's national thematic portal. Half the sampled catalogue declares no licence at all (link-only); the other half is a bare "Public Domain" assertion (PUBLIC-DOMAIN class).
RDW Open Data doesn't expose a machine-readable breakdown of who publishes what, so there's no reliable publisher ranking to show here. Vizzie still surfaces each dataset's own publisher as you browse.
