Source[det]rdf_compare(-Diff, +Left, +Right)
True if the RDF terms Left and Right are ordered according to the comparison operator Diff. The ordering is defines as:

  • Literal < BNode < IRI
  • For literals

    • Numeric < non-numeric
    • Numeric literals are ordered by value. If both are equal, floats are ordered before integers.
    • Other data types are ordered lexicographically.

  • BNodes and IRIs are ordered lexicographically.

Note that this ordering is a complete ordering of RDF terms that is consistent with the partial ordering defined by SPARQL.
