> The concept of reification has always been part of RDF, but expressing it
in RDF concrete syntaxes such as Turtle, N-Triples, and RDF/XML has been
verbose and cumbersome. This specification describes a new, more compact
conceptual data model and Turtle concrete syntax for reification known as
RDF* (pronounced "RDF star") and Turtle* (pronounced "Turtle star"),
respectively. This model and syntax enable the creation of concise triples
that reference other triples as subject and object resources.
