NDE Dataset Register

Netwerk Digitaal Erfgoed, beheerd door het Nationaal ArchiefNetherlands, dataset

The Dataset Register of the Dutch Digital Heritage Network is the catalogue of Dutch heritage data: archives, museums, libraries and municipalities register their dataset descriptions, the register harvests and validates them and loads them into a SPARQL endpoint. On 16 October 2026 it held 3,401 datasets with a valid registration from 159 publishers. The register contains descriptions, not the data itself: each description points to downloads or APIs (OAI-PMH, SPARQL, IIIF) at the institution. It is maintained by the National Archives.
