SPARUL


SPARUL, or SPARQL/Update, was a declarative data manipulation language that extended the SPARQL 1.0 query language standard. SPARUL provided the ability to insert, delete and update RDF data held within a triple store or quad store. SPARUL was originally written by Hewlett-Packard and has been used as the foundation for the current W3C recommendation entitled SPARQL 1.1 Update. With the publication of SPARQL 1.1, SPARUL is superseded and should only be consulted as a source of inspiration for possible future refinements of SPARQL, but not for real-world applications.

Examples

Adding some triples to a graph. The snippet describes two RDF triples to be inserted into the default graph of the RDF store.

PREFIX dc:
INSERT DATA

This SPARQL/Update request contains a triple to be deleted and a triple to be added. The requested change happens in the named graph identified by the URI http://example/bookStore.

PREFIX dc:
DELETE DATA FROM
INSERT DATA INTO

The example below has a request to delete all records of old books

PREFIX dc:
PREFIX xsd:
DELETE
WHERE


This snippet copies records from one named graph to another named graph based on a pattern.

PREFIX dc:
PREFIX xsd:
INSERT INTO
WHERE
