Very simple metadata support along the lines of

        $wiki->write_node( "Reun Thai", "A restaurant", undef,
            { postcode => "W6 9PL",
              category => [ "Thai Food", "Restaurant", "Hammersmith" ] } );

        @nodes = $wiki->list_nodes_by_metadata( metadata_type  => "category",
                                                metadata_value => "Pub" );

Have also been thinking about plugins, something like:

  use CGI::Wiki;
  use CGI::Wiki::Plugin::Location;

  my $locator = CGI::Wiki::Plugin::Location->new;

  my $wiki = CGI::Wiki->new;
  $wiki->register_plugin($locator);

  $wiki->write_node( "Jerusalem Tavern", "A good pub", $checksum,
                     { os_x => 531674, os_y => 181950 } );

  # Just retrieve the co-ordinates.
  my ( $x, $y ) = $locator->coordinates( node => "Jerusalem Tavern" );

  # Find the distance between two nodes.
  my $distance = $locator->distance( from => "Jerusalem Tavern",
                                     to   => "Calthorpe Arms"    );

  # Find the nearest five other things that our wiki knows about.
  my @others = $locator->find_nearest( node => "Jerusalem Tavern",
                                       number => 5  );


Also, the UseMod formatter is ready for release as soon as chromatic
releases Text::WikiFormat 0.6, which should be soon.
