1.5.61. How Do I Clean Up Errant Data using SPARQL Update Language?
¶
Why?
All data endeavors involve varying degrees of prospective and retrospective error correction.
¶
How?
Given a triple in a Virtuoso Quad store that contains an errant URI e.g. one that accidentally contains spaces, here is a SPARQL example that showcases how to delete said triple using a built-in function:
DELETE FROM <your_graph>
{
`iri("http://isbsg.clearbluewater.com.au/wsf/datasets/378/Capers Jones_107_12122011081257")`
a <http://isbsg.org/ontology/data/Dataset>
};
