Suppose the following situation:

  • There is a specific triple somewhere in a massive dataset in a Virtuoso DBMS.

  • There are too many possible named graphs associated with the pattern so

    SPARQL DELETE

    (which requires

    FROM

    i.e., Named Graph scoping) isn't adequate

What is the solution?

Using SQL you can execute the following:

SQL> SPARQL
DELETE FROM rdf_quad
WHERE s = iri_to_id ('http://linkeddata.uriburner.com/about/id/entity/http/twitter.com/kidehen')
  AND o = iri_to_id ('http://purl.org/ontology/bibo/Document')
  AND p = iri_to_id ('http://www.w3.org/1999/02/22-rdf-syntax-ns#type');
