NAME¶
URI::NamespaceMap - Class holding a collection of namespaces
VERSION¶
Version 0.22
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' )
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, 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 namespace object (if any) associated with the given
prefix.
- "list_namespaces"
- Returns an array of URI::Namespace objects with all the namespaces.
- "list_prefixes"
- Returns an array of prefixes.
- "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.
