NAME

       RDF::Trine::Statement - Class for triples and triple patterns

VERSION

       This document describes RDF::Trine::Statement version 1.000

METHODS

       "new ( $s, $p, $o )"
	   Returns a new Triple structure.

       "construct_args"
	   Returns a list of arguments that, passed to this class' constructor, will produce a clone of this algebra pattern.

       "nodes"
	   Returns the subject, predicate and object of the triple pattern.

       "node_names"
	   Returns the method names for accessing the nodes of this statement.

       "subject"
	   Returns the subject node of the triple pattern.

       "predicate"
	   Returns the predicate node of the triple pattern.

       "object"
	   Returns the object node of the triple pattern.

       "as_string"
	   Returns the statement in a string form.

       "has_blanks"
	   Returns true if any of the nodes in this statement are blank nodes.

       "sse"
	   Returns the SSE string for this algebra expression.

       "from_sse ( $string, $context )"
	   Parses the supplied SSE-encoded string and returns a RDF::Trine::Statement object.

       "type"
	   Returns the type of this algebra expression.

       "referenced_variables"
	   Returns a list of the variable names used in this algebra expression.

       "definite_variables"
	   Returns a list of the variable names that will be bound after evaluating this algebra expression.

       "clone"
       "bind_variables ( \%bound )"
	   Returns a new algebra pattern with variables named in %bound replaced by their corresponding bound values.

       "subsumes ( $statement )"
	   Returns true if this statement will subsume the $statement when matched against a triple store.

       "from_redland ( $statement )"
	   Given a RDF::Redland::Statement object, returns a perl-native RDF::Trine::Statement object.

       "rdf_compatible"
	   Returns true if and only if the statement can be expressed in RDF. That is, the subject of the statement must be a resource or blank
	   node; the predicate must be a resource; and the object must be a resource, blank node or literal.

	   RDF::Trine::Statement does allow statements to be created which cannot be expressed in RDF - for instance, statements including
	   variables.

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.
