An RDF blank node. @author Mariusz Cygan
org.openrdf.model.BNode
A blank node (aka bnode, aka anonymous node). A blank node has an identifier to be able to compare it to other blank nodes internally. Please note that, conceptually, blank node equality can only be determined by examining the statements that refer to them.
