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/>.
