I figured out how to delete reified statements but I feel as though there
has to be a more efficient way of doing this. The way I am going about it
now is as follows :
DELETE {?s ?p ?o}
WHERE {
?s rdf:subject <https://myapp/servicea/id/11111111>
?s rdf:predicate <urn:myapp:id> .
?s ?p ?o
}
DELETE {?s ?p ?o}
WHERE {
?s rdf:subject <https://myapp/servicea/id/21111111>
?s rdf:predicate <urn:myapp:id> .
?s ?p ?o
}
DELETE {?s ?p ?o}
WHERE {
?s rdf:subject <https://myapp/servicea/id/31111111>
?s rdf:predicate <urn:myapp:id> .
?s ?p ?o
}
Is there a way to combine all of these into one DELETE statement? I
couldn't figure out a way to do that.
