NAME

       RDF::Closure::Model - RDF::Trine::Model-compatible inferface

DESCRIPTION

       This module provides a subclass of RDF::Trine::Model allowing you to dollop some reasoning into existing RDF::Trine code very easily. While
       RDF::Closure::Engine allows you to infer lots of new statements from an existing model, this class also allows you to add and remove
       statements from the reasoned model with new inferences calculated on-the-fly.

       Removing a statement is much slower than adding one, though adding a statement isn't what you'd call fast. Juditious use of
       "begin_bulk_ops" and "end_bulk_ops" is recomnmended.

       If a lot of statements have been added and removed from a model since it was created, then it's theoretically possible for the inferred
       data to contain statements which are no longer entailed by the explicit data, or for the inferred data to be missing some inferences. A
       "recalculate" method is provided which allows you to re-run the inference from scratch.

   Constructor
       o   "new($input, [, engine => $engine ] [, store => $store ])"

	   Instantiates a module. $input may be undef, an existing RDF::Trine::Model or an RDF::Trine::Store. The input will not be modified.

	   $engine is the inference engine to use; a string suitable for passing to "RDF::Closure::Engine->new"; defaults to 'RDFS'.

	   $store is an RDF::Trine::Store to use to build the inferred model in; defaults to a new, temporary store.

   Methods
       This package inherits from RDF::Trine::Model and provides all the methods it does. It additionally provides:

       o   "entailment_regime"

	   Returns a URI string identifying the type of inference in use.

       o   "recalculate"

	   Drops and re-infers all inferred data.

SEE ALSO

       RDF::Closure, RDF::Closure::Engine, RDF::Trine::Model.

       Take careful note of the "begin_bulk_ops" and "end_bulk_ops" methods present in RDF::Trine::Model. Judicious use of them can seriously
       speed up this module.

NAME

       RDF::Trine - An RDF Framework for Perl

VERSION

       This document describes RDF::Trine version 1.000

SYNOPSIS

	 use RDF::Trine;

DESCRIPTION

       RDF::Trine provides an RDF framework with an emphasis on extensibility, API stability, and the presence of a test suite. The package
       consists of several components:

       o   RDF::Trine::Model - RDF model providing access to a triple store.

       o   RDF::Trine::Parser - RDF parsers for various serialization formats including RDF/XML, Turtle, RDFa, and RDF/JSON.

       o   RDF::Trine::Store::Memory - An in-memory, non-persistant triple store.

       o   RDF::Trine::Store::DBI - A triple store for MySQL and SQLite, based on the Redland schema.

       o   RDF::Trine::Iterator - Iterator classes for variable bindings and RDF statements, used by RDF::Trine::Store, RDF::Trine::Model, and
	   RDF::Query.

       o   RDF::Trine::Namespace - A convenience class for easily constructing RDF node objects from URI namespaces.

FUNCTIONS

       "iri ( $iri )"
	   Returns a RDF::Trine::Node::Resource object with the given IRI value.

       "blank ( $id )"
	   Returns a RDF::Trine::Node::Blank object with the given identifier.

       "literal ( $value, $lang, $dt )"
	   Returns a RDF::Trine::Node::Literal object with the given value and optional language/datatype.

       "variable ( $name )"
	   Returns a RDF::Trine::Node::Variable object with the given variable name.

       "statement ( @nodes )"
	   Returns a RDF::Trine::Statement object with the supplied node objects.

       "store ( $config )"
	   Returns a RDF::Trine::Store object based on the supplied configuration string.  See RDF::Trine::Store for more information on store
	   configuration strings.
