View Source RDF.BlankNode (RDF.ex v1.0.0)

An RDF blank node (aka bnode) is a local node of a graph without an IRI.

This module can also be used as RDF.Resource.Generator for the generation of random identifiers, which is using the new/0 function. For the generation of value-based blank nodes, you can use RDF.BlankNode.Generator.
