24 "equals ( $graph1, $graph2 )"
25 Returns true if the invocant and $graph represent two equal RDF
26 graphs (e.g. there exists a bijection between the RDF statements
27 of the invocant and $graph).
28
29 "is_subgraph_of ( $graph1, $graph2 )"
30 Returns true if the invocant is a subgraph of $graph. (i.e. there
31 exists an injection of RDF statements from the invocant to $graph.)
32
33 "injection_map ( $graph1, $graph2 )"
34 If the invocant is a subgraph of $graph, returns a mapping of blank
35 node identifiers from the invocant graph to $graph as a hashref.
36 Otherwise returns false. The solution is not always unique; where
37 there exist multiple solutions, the solution returned is arbitrary.
38
39 "split_blank_statements( $iter )"
40 Returns two array refs containing bindings from $iter, with
41 bindings containing blank nodes and bindings without any blank
42 nodes, respectively.
