org.apache.clerezza.rdf.core.BNode
A Blank Node, extends a NonLiteral. represents a resource, but does not indicate a URI for the resource. Blank nodes act like existentially qualified variables in first order logic. @author reto

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.
