About Grunnlink

Grunnlink is a searchable index of historical, renamed and vanished street and place names in Groningen. Every name is sourced and, where possible, linked to BAG, Wikidata and the Groningen Archives. The aim: an open, citable authority that plugs into the Dutch Digital Heritage Network (NDE).

Public API

All data is already publicly queryable:

/reconcile — Reconciliation API: match old or uncertain names to modern ones (works directly in OpenRefine).
/id/:type/:slug — Permanent URIs: every name returns JSON-LD, Turtle or HTML.
/api/suggest?q= — Autocomplete: typeahead suggestions by name.
/api/map — Map data: GeoJSON of located (vanished) places.

Coming soon: a SPARQL endpoint and bulk RDF dumps.
