SPARQLInsert[patterntemplate]

is an insert operator that can be applied to an RDFStore, which inserts data generated from template, based on solutions of matching pattern.

Details and Options

  • SPARQLInsert can be used in SPARQLExecute to insert data into a SPARQL endpoint.
  • In SPARQLInsert[patterntemplate], template corresponds to the INSERT clause, and pattern corresponds to the WHERE clause of a SPARQL update request.

Basic Examples  (1)

Wolfram Language code: Needs["GraphStore`"]

Specify a graph containing data about geometric objects:

Wolfram Language code: ex[s_] := URL["http://example.org/" <> s];
Wolfram Language code: graph = RDFStore[{ RDFTriple[ex["square"], ex["edgeLength"], 1], RDFTriple[ex["square"], ex["area"], 1], RDFTriple[ex["disk"], ex["radius"], 1], RDFTriple[ex["disk"], ex["area"], 3.14] }];

Add the diameter to objects that have a radius:

Wolfram Language code: graph = graph//SPARQLInsert[{ RDFTriple[SPARQLVariable["obj"], ex["radius"], SPARQLVariable["r"]], "d" -> 2SPARQLVariable["r"] } -> RDFTriple[SPARQLVariable["obj"], ex["diameter"], SPARQLVariable["d"]]]

Look up diameters:

Wolfram Language code: graph//SPARQLSelect[RDFTriple[SPARQLVariable["obj"], ex["diameter"], SPARQLVariable["d"]]]

Applications  (1)

Wolfram Language code: Needs["GraphStore`"]

Export an insert operator as a SPARQL update string:

Wolfram Language code: ExportString[ SPARQLInsert[{ RDFTriple[SPARQLVariable["obj"], URL["http://example.org/radius"], SPARQLVariable["r"]], "d" -> 2SPARQLVariable["r"] } -> RDFTriple[SPARQLVariable["obj"], URL["http://example.org/diameter"], SPARQLVariable["d"]]], "SPARQLUpdate", "Prefixes" -> <|"ex" -> "http://example.org/"|> ]
