voiD store

Known Limitations

There is a known limitation with this service at present, due to the use of 3store as our underlying storage mechanism. We are investigating moving to 4store. Unfortuantely, 3store does not seem to support passing the results of a variable binding to the pattern part of a regex. This means the following query will fail –

    SELECT ?dataset
    WHERE {
      ?dataset a void:Dataset .
      ?dataset void:uriRegexPattern ?pattern .
      FILTER(REGEX("http://dbpedia.org/resource/Amsterdam", ?pattern))
    }

        

If you have a URI and wish to seek SPARQL endpoints that may contain that URI, then try the lookup service.
