Interface Union
- All Superinterfaces:

public interface Union
- extends SetOperation
The set union of two graphs - all of the items in the first graph are
added to the second graph (no duplicates).
In the case of blank nodes, as noted in 1.5 in the RDF Semantics Document (http://www.w3.org/TR/rdf-mt/#unlabel) a
union of two graphs corresponds to a conjunction. The merge of two separate graphs, graphs from two different
sources, results in a merge - where all blank nodes will retain their identity.
