NAME
   RDF::TriN3 - notation 3 extensions for RDF::Trine

DESCRIPTION
   This module extends RDF::Trine in three ways:

   *   Adds a Notation 3 parser.

   *   Adds a Notation 3 serializer.

   *   Provides a subclass of literals to represent Notation 3 formulae.

   In addition, a parser is provided for Notation 3 extended with
   ShorthandRDF notation - <http://esw.w3.org/ShorthandRDF>.

BUGS AND LIMITATIONS
   Implementing N3 logic and the cwm built-ins is considered outside the
   scope of this distribution, though I am interested in doing that as part
   of a separate project.

   RDF::TriN3 currently relies entirely on RDF::Trine to provide
   implementations of the concept of graphs, and storage. Thus any graphs
   that can't be represented using RDF::Trine can't be represented in
   RDF::TriN3. RDF::Trine's graph model is a superset of RDF, but a subset
   of Notation 3's model. While this allows literal subjects, and literal
   and blank node predicates, these may not be supported by all storage
   engines; additionally top-level variables (?foo), and top-level @forSome
   and @forAll (i.e. not nested inside a formula) might cause problems.

   RDF::Trine::Store::DBI has some issues with literal subjects, and
   literal and blank node predicates, allowing them to be stored, but not
   retrieved. From version 0.128, RDF::Trine::Store::DBI offers a
   "clear_restrictions" method that should resolve these issues.
   RDF::Trine::Store::Memory is fine. Other stores are not tested.

   Please report any bugs to <http://rt.cpan.org/>.
