Hi,
I have to delete all the data about particular resources in the triplestore,
and I'm finding that it's taking an inordinately long time. I have tried
separate queries like:
DELETE WHERE {
<http://example.org/x> ?p ?o .
}
;
DELETE WHERE {
<http://example.org/y> ?p ?o .
}
;
…
and I have tried a combined query like:
DELETE {
?s ?p ?o .
} WHERE {
?s ?p ?o .
FILTER (
?s = <http://example.org/x> ||
?s = <http://example.org/y> ||
...
)
}
Both of these seem to perform OK on my OWLIM-Lite instance but not on the
OWLIM-SE instance. Could this difference between OWLIM-Lite performance and
OWLIM-SE performance be down to a difference in the reasoning that's enabled (I
have an empty ruleset on the OWLIM-Lite instance, but currently have the
default owl-horst-optimized' on the OWLIM-SE instance)?
Is there an alternative method of deleting all the data about a particular
resource that I should use?
Thanks,
Jeni
