NAME

       URI::NamespaceMap - Class holding a collection of namespaces

VERSION

       Version 0.30

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.

       "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.
