SPARQL 1.1 specifies that it supports a subset of XPath 2.0 constructor functions (i.e. casting) on all SPARQL operand datatypes, as well as any additional datatypes imposed by the RDF data model. These datatypes are listed here: https://www.w3.org/TR/sparql11-query/#operandDataTypes .

Although implicit conversion is supported, and explicit casting is supported for the SPARQL operand dataypes, RDF4J currently has no explicit casting operators for the additional datatypes:

  • xsd:nonPositiveInteger
  • xsd:negativeInteger
  • xsd:long
  • xsd:int
  • xsd:short
  • xsd:byte
  • xsd:nonNegativeInteger
  • xsd:unsignedLong
  • xsd:unsignedInt
  • xsd:unsignedShort
  • xsd:unsignedByte
  • xsd:positiveInteger
