This document describes Attean::Result version 0.030


  use v5.14;
  use Attean;
  my $result = Attean::Result->new(bindings => { name => $literal, homepage => $iri } );
  my @vars = $result->variables; # ('name', 'homepage')
  my $term = $result->value('name'); # $term == $literal


The Attean::Result class represents a SPARQL result (a set of bindings from
