Geo::Address::Mail::Standardizer - A role for Geo::Address::Mail standardization


This module provides an interface for writing address standardization as well as a class to represent the results of a standarization process.

    package Geo::Address::Mail::Standardizer::My;
    use Moose;

    with 'Geo::Address::Mail::Standardizer';

    # use it

    my $std = Geo::Address::Mail::Standardizer::My->new(...);
    my $address = Geo::Address::Mail::MyCountry;
    my $results = $std->standardize($address);


This module provides a simple API. Your Standardizer implementation is likely for a specific locale such as the US, UK or whatever. You should provide a standardize method that accepts the appropriate subclass (Geo::Address::Mail::YourCountry). You would then use the information in the supplied address object with your standardization mechanism. You should not change the argument. Instead, create a new Address object and use it with the Geo::Address::Mail::Standardizer::Results object, setting any changed values:

  sub standardize {
      my ($self, $address) = @_;

      # contact the USPS or your local postal service in your country
      # or implement some algorithm or whatever

      my $results = Geo::Address::Mail::Standardizer::Results->new;
      my $new_addr = $address->clone;
      for(...) { # iterate over the results of your standardization mechanism
        $results->set_changed($field, $new_value) if $changed;

      return $results;
