Using the query service

  • Query service lives here
  • Documentation on WbStack's query service (general)
  • Queries are made in SPARQL
  • Note that you cannot use the standard Wikidata prefixes when constructing your query. Instead, fill in the P# and Q# in the following:
    • Property: <http://cul-dlc-test.wiki.opencura.com/prop/direct/P#>
    • Item: <http://cul-dlc-test.wiki.opencura.com/entity/Q#>
  • Example queries
    • Get the URIs for all library locations in the Hyacinth Locations vocabulary (Q-numbers only)
      • SELECT * WHERE { ?libraryQnumber <http://cul-dlc-test.wiki.opencura.com/prop/direct/P1> <http://cul-dlc-test.wiki.opencura.com/entity/Q3> . }
    • Get the labels for all library locations in the Hyacinth Locations vocabulary
      • SELECT ?label WHERE { ?b <http://cul-dlc-test.wiki.opencura.com/prop/direct/P1> <http://cul-dlc-test.wiki.opencura.com/entity/Q3> ; <http://www.w3.org/2000/01/rdf-schema#label> ?label .}
