SPARQLConstruct

[Experimental]

SPARQLConstruct[patterntemplate]

is a query operator that can be applied to an RDFStore, which returns an RDFStore generated from template, based on solutions of matching pattern.

SPARQLConstruct[pattern]

uses pattern as template.

Details and Options

  • SPARQLConstruct can be used in SPARQLExecute to query a SPARQL endpoint.
  • The result of executing SPARQLConstruct[patterntemplate] is a RDFStore object containing for each solution the triples of template where variables have been replaced with values of this solution.
  • In SPARQLConstruct[pattern], pattern can take the same form as in SPARQLSelect[pattern].
