NAME

6       RDF::TriN3 - notation 3 extensions for RDF::Trine
7

DESCRIPTION

9       This module extends RDF::Trine in three ways:
10
11       •   Adds a Notation 3 parser.
12
13       •   Adds a Notation 3 serializer.
14
15       •   Provides a subclass of literals to represent Notation 3 formulae.
16
17       In addition, a parser is provided for Notation 3 extended with
18       ShorthandRDF notation - <http://esw.w3.org/ShorthandRDF>.

BUGS AND LIMITATIONS

21       Implementing N3 logic and the cwm built-ins is considered outside the
22       scope of this distribution, though I am interested in doing that as
23       part of a separate project.
24
25       RDF::TriN3 currently relies entirely on RDF::Trine to provide
26       implementations of the concept of graphs, and storage. Thus any graphs
27       that can't be represented using RDF::Trine can't be represented in
28       RDF::TriN3. RDF::Trine's graph model is a superset of RDF, but a subset
29       of Notation 3's model. While this allows literal subjects, and literal
30       and blank node predicates, these may not be supported by all storage
31       engines; additionally top-level variables (?foo), and top-level
32       @forSome and @forAll (i.e. not nested inside a formula) might cause
33       problems.
34
35       RDF::Trine::Store::DBI has some issues with literal subjects, and
36       literal and blank node predicates, allowing them to be stored, but not
37       retrieved. From version 0.128, RDF::Trine::Store::DBI offers a
38       "clear_restrictions" method that should resolve these issues.
39       RDF::Trine::Store::Memory is fine. Other stores are not tested.
