The RDF model interfaces are organized in the following hierarchy:

       Value          Statement       Model
      /     \
     /       \
 Resource  Literal
   /  \
  /    \
IRI   BNode

An individual RDF triple or statement is represented by the Statement interface. Collections of RDF statements are represented by the Model interface.

Creation of new Model elements (IRIs, Literals, BNodes, Statements) is done by means of a ValueFactory
