SPARQLDeleteData

SPARQLDeleteData[data]

is an update operator that can be applied to an RDFStore, which deletes the data data.

Details and Options

  • SPARQLDeleteData can be used in SPARQLExecute to delete data from a SPARQL endpoint.
  • data is usually a list of RDFTriple.
  • data is normally deleted from the default graph.
  • Triples can be deleted from a named graph using SPARQLGraph.

Examples

Basic Examples  (1)

Wolfram Language code: Needs["GraphStore`"];

Data about paintings:

Wolfram Language code: ex[s_] := URL["http://example.org/" <> s];
Wolfram Language code: paintingsGraph = RDFStore[{ RDFTriple[ex["monaLisa"], ex["depicts"], "woman"], RDFTriple[ex["starryNight"], ex["depicts"], "cypress"], RDFTriple[ex["starryNight"], ex["depicts"], "sky"], RDFTriple[ex["starryNight"], ex["depicts"], "tomato"] }]

Delete a triple about "The Starry Night":

Wolfram Language code: paintingsGraph = paintingsGraph//SPARQLDeleteData[RDFTriple[ex["starryNight"], ex["depicts"], "tomato"]]
