SPARQL endpoint

You can retrieve dataset descriptions registered by yourself and others from our triple store’s web interface.

Alternatively, use the SPARQL endpoint at https://datasetregister.netwerkdigitaalerfgoed.nl/sparql directly. For example using the Comunica SPARQL client:

comunica-sparql sparql@https://datasetregister.netwerkdigitaalerfgoed.nl/sparql 'select * {?s a <http://www.w3.org/ns/dcat#Dataset> . ?s ?p ?o . } limit 100'

Or curl:

curl -H Accept:application/sparql-results+json --data-urlencode 'query=select * {?s a <http://www.w3.org/ns/dcat#Dataset> . ?s ?p ?o . } limit 100'  https://datasetregister.netwerkdigitaalerfgoed.nl/sparql

Queries​

You can get some help building queries at the Dataset Register website, using the ‘SPARQL’ button.

You probably only want to view currently valid datasets. For this, follow the link from dataset to registration URL and check whether that URL is valid:

PREFIX dcat: <http://www.w3.org/ns/dcat#>
PREFIX schema: <http://schema.org/>
SELECT * {
  ?dataset a dcat:Dataset ;
    schema:subjectOf ?registrationUrl .
  ?registrationUrl schema:additionalType <https://data.netwerkdigitaalerfgoed.nl/registry/valid>
}
