       This module provides an object to manage multiple namespaces for creating URI::Namespace objects and for
       serializing.

       "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. With that, you can do e.g.

             my $map = URI::NamespaceMap->new( 'rdf', 'xsd', 'foaf' );

           and have the correct mappings added automatically.

       "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.

       "each_map"
           Returns  an  2-element  list  where the first element is a prefix and the second is the corresponding
           URI::Namespace object.

       "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.

       URI::NamespaceMap - Class holding a collection of namespaces

       You can find documentation for this module with the perldoc command.

           perldoc URI::NamespaceMap

         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' )
         $map->foaf; # Returns URI::Namespace object
         while (my ($prefix, $nsURI) = $map->each_map) {
                $node->setNamespace($nsURI->as_string, $prefix); # For use with XML::LibXML
         }

       Version 1.12

       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.
