I just wanted to quick mention one feature of the Ordnance Survey linked data SPARQL endpoints that I think it pretty neat. Go to the SPARQL endpoint and try one of the queries from my last four blogs posts. In this post I’ll got with the following simple query (recall this query gets the name, lat, long, gss code and unit_id for all districts in Great Britain):
select ?name ?lat ?long ?gss ?unit_id
?x <http://www.w3.org/2000/01/rdf-schema#label> ?name .
?x <http://www.w3.org/2003/01/geo/wgs84_pos#lat> ?lat .
?x <http://www.w3.org/2003/01/geo/wgs84_pos#long> ?long .
?x <http://data.ordnancesurvey.co.uk/ontology/admingeo/hasUnitID> ?unit_id .
You will notice that on hitting the query button that a box will appear that says “Request” and a rather long URL will appear:
where LONG_URL is your long URL. You should now see the JSON response from that GET request.
