  • Possible values for the gi are:
  • URL["iri"]graph identified by the given identifier
    "Default"default graph
  • The graph identified by g2 is cleared before data is inserted.

Examples

Basic Examples  (1)

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

Import a catalog of paintings:

Wolfram Language code: catalogStore = ImportString[" prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> prefix schema: <http://schema.org/> prefix ex: <http://example.org/> ex:LandschaftMitOlivenbaumen rdfs:label \"Landschaft mit Olivenb\\u00e4umen\"@de ; schema:author ex:vanGogh . ex:DerSamann rdfs:label \"Der S\\u00e4mann\"@de ; schema:author ex:vanGogh . ex:backup\\/2018-07-26 { ex:LandschaftMitOlivenbaumen rdfs:label \"Landschaft mit Olivenb\\u00e4umen\"@de ; schema:author ex:vanGogh . ex:leMoulinDeLaGalette rdfs:label \"Le Moulin de la Galette\"@fr ; schema:author ex:vanGogh . } ", "TriG"]

Restore the default graph from a backup stored in a named graph:

Wolfram Language code: catalogStore = catalogStore//SPARQLCopy[URL["http://example.org/backup/2018-07-26"], "Default"]

Review the labels of paintings in the default graph:

Wolfram Language code: catalogStore//SPARQLSelect[RDFTriple[RDFBlankNode[], URL["http://www.w3.org/2000/01/rdf-schema#label"], SPARQLVariable["label"]]]
