Detailed Description

This class represents a BlankNode in RDF (i.e. an unspecific uri). Each blank node is uniquely identified by an UUID.

The blank node maybe associated with a label. However the label is not considered to check if two blank nodes are equals, only the UUID is used. The label is mainly used for display purposes and as a hint when serializing documents.
