Tools & capabilities
Overheid Nl tools 4
search_datasetsSearch the data.overheid.nl catalogue of Dutch government open data (CKAN package_search). Returns matching datasets with titles/descriptions (mostly Dutch). Query may be Dutch or English; Dutch matches more.dataset_detailsFull dataset record by id or slug (CKAN package_show), including its resources. Each resource has a download "url" and "format" (CSV/JSON/etc.) — the portal is metadata-only, so fetch those URLs to get the actual data.list_organizationsList publishing organizations (ministries/agencies/provinces) on data.overheid.nl (CKAN organization_list). Use an org "name" in search_datasets fq, e.g. "organization:<name>".list_groupsList thematic groups/categories on data.overheid.nl (CKAN group_list). Note: this portal currently exposes no groups (returns an empty list) — prefer fq facets on search_datasets to narrow by theme.
