NAME

       RDF::Trine::Node::Literal - RDF Node class for literals

VERSION

       This document describes RDF::Trine::Node::Literal version 1.000

METHODS

       Beyond the methods documented below, this class inherits methods from the RDF::Trine::Node class.

       "new ( $string, $lang, $datatype, $canonical_flag )"
	   Returns a new Literal structure.

       "literal_value"
	   Returns the string value of the literal.

       "literal_value_language"
	   Returns the language tag of the ltieral.

       "literal_datatype"
	   Returns the datatype of the literal.

       "value"
	   Returns the literal value.

       "sse"
	   Returns the SSE string for this literal.

       "as_string"
	   Returns a string representation of the node.

       "as_ntriples"
	   Returns the node in a string form suitable for NTriples serialization.

       "type"
	   Returns the type string of this node.

       "has_language"
	   Returns true if this literal is language-tagged, false otherwise.

       "has_datatype"
	   Returns true if this literal is datatyped, false otherwise.

       "equal ( $node )"
	   Returns true if the two nodes are equal, false otherwise.

       "canonicalize_literal_value ( $string, $datatype, $warn )"
	   If $datatype is a recognized datatype, returns the canonical lexical representation of the value $string. Otherwise returns $string.

	   Currently, xsd:integer, xsd:decimal, and xsd:boolean are canonicalized.  Additionally, invalid lexical forms for xsd:float, xsd:double,
	   and xsd:dateTime will trigger a warning.

       "is_canonical_lexical_form"
       "is_valid_lexical_form"
	   Returns true if the node is of a recognized datatype and has a valid lexical form for that datatype. If the lexical form is invalid,
	   returns false. If the datatype is unrecognized, returns zero-but-true.

       "is_numeric_type"
	   Returns true if the literal is a known (xsd) numeric type.

       "numeric_value"
	   Returns the numeric value of the literal (even if the literal isn't a known numeric type.

NAME

       RDF::Trine::NamespaceMap - Collection of Namespaces

VERSION

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

SYNOPSIS

	   use RDF::Trine::NamespaceMap;
	   my $map = RDF::Trine::NamespaceMap->new( \%namespaces );
	   $serializer->serialize_model_to_string( $model, namespaces => $map );

	   $map->add_mapping( foaf => 'http://xmlns.com/foaf/0.1/' );
	   my $foaf_namespace = $map->foaf;
	   my $foaf_person    = $map->foaf('Person');

DESCRIPTION

       This module provides an object to manage multiple namespaces for creating RDF::Trine::Node::Resource objects and for serializing.

METHODS

       "new ( [ \%namespaces ] )"
	   Returns a new namespace map object. You can pass a hash reference with mappings from local names to namespace URIs (given as string or
	   RDF::Trine::Node::Resource).

       "add_mapping ( $name => $uri )"
	   Adds a new namespace to the map. The namespace URI can be passed as string or some object, that provides an uri_value method.

       "remove_mapping ( $name )"
	   Removes a namespace from the map.

       "namespace_uri ( $name )"
	   Returns the namespace object (if any) associated with the given name.

       "uri ( $prefixed_name )"
	   Returns a URI (as RDF::Trine::Node::Resource) for an abbreviated string such as 'foaf:Person'.

WARNING

       Avoid using the names 'can', 'isa', 'VERSION', and 'DOES' as namespace prefix, because these names are defined as method for every Perl
       object by default.  The method names 'new' and 'uri' are also forbidden.
