Main Principals

This is the production release of the British Museum's linked data and SPARQL endpoint service using the CIDOC CRM ontology. It contains the data for over 2 million objects and provides one or more images for over 750,000 records. If you experience any issues please send a mail to:

Linked Data

All British Museum URIs start with HTTP and are within the domain We have attempted to map fields from our collections system to URIs which follow a pattern in the url structure which is demonstrated below.

Sparql Endpoint

The sparql endpoint allows querying of the triple store. The queries can be made in 2 ways:

  • navigating to /Sparql and subitting queries via the editor
  • HTTP-GET requests to (RESTful API

A simple query for the Rosetta Stone is

<> ?p ?o .

This creates the URL*%0D%0AWHERE+{}+LIMIT+100&_implicit=false&implicit=true&_equivalent=false&_form=%2Fsparql returns xml (in the browser this is a downloadable file) returns json


Returns the first level of the Rosetta stone graph and is the equivalent of http request

As will be seen when queries are submitted via the editor, the URL will define the parameters to the service:

  • Query: The SPARQL Query
  • The Endpoint is CORS compliant and therefore available through JavaScript calls from a browser.

    The same results can be achieved by submitting a header (Accept) in the request:

    • Sparql Results XML (Content Type: application/sparql-results+xml): Accept: application/sparql-results+xml
    • Sparql Results JSON (Content Type: application/sparql-results+json): Accept: application/sparql-results+json
