NAME
URI::NamespaceMap - Class holding a collection of namespaces
VERSION
Version 1.00
SYNOPSIS
use URI::NamespaceMap;
my $map = URI::NamespaceMap->new( { xsd => 'http://www.w3.org/2001/XMLSchema#' } );
$map->namespace_uri('xsd')->as_string;
my $foaf = URI::Namespace->new( 'http://xmlns.com/foaf/0.1/' );
$map->add_mapping(foaf => $foaf);
$map->add_mapping(rdf => 'http://www.w3.org/1999/02/22-rdf-syntax-ns#' );
$map->list_prefixes; # ( 'foaf', 'rdf', 'xsd' )
$map->foaf; # Returns URI::Namespace object
DESCRIPTION
This module provides an object to manage multiple namespaces for creating
URI::Namespace objects and for serializing.
METHODS
`new ( [ \%namespaces | @prefixes | @uris ] )`
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) or namespaces_map with a hashref. You may
also pass an arrayref containing just prefixes and/or namespace URIs,
and the module will try to guess the missing part. To use this
feature, you need RDF::NS::Curated, RDF::NS, XML::CommonNS or
RDF::Prefixes, or preferably all of them.
`add_mapping ( $name => $uri )`
Adds a new namespace to the map. The namespace URI can be passed as
string or a URI::Namespace object.
`remove_mapping ( $name )`
Removes a namespace from the map given a prefix.
`namespace_uri ( $name )`
Returns the URI::Namespace object (if any) associated with the given
prefix.
$name
This module creates a method for all the prefixes, so you can say e.g.
$map->foaf
and get a URI::Namespace object for the FOAF namespace. Since
URI::Namespace does the same for local names, you can then say e.g.
$map->foaf->name
to get a full URI.
`list_namespaces`
Returns an array of URI::Namespace objects with all the namespaces.
`list_prefixes`
Returns an array of prefixes.
`guess_and_add ( @string_or_uri )`
Like in the constructor, an array of strings can be given, and the
module will attempt to guess appropriate mappings, and add them to the
map.
`uri ( $prefixed_name )`
Returns a URI for an abbreviated string such as 'foaf:Person'.
prefix_for `uri ($uri)`
Returns the associated prefix (or potentially multiple prefixes, when
called in list context) for the given URI.
abbreviate `uri ($uri)`
Complement to "namespace_uri". Returns the given URI in `foo:bar`
format or `undef` if it wasn't matched, therefore the idiom
my $str = $nsmap->abbreviate($uri_node) || $uri->as_string;
may be useful for certain serialization tasks.
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. Names of
methods of Moose::Object must also be avoided.
Using them will result in an error.
