NAME
    XML::Generator::RFC822::RDF - generate RDF/XML SAX2 events for RFC822
    messages

SYNOPSIS
      my $folder = Email::Folder->new($path_mbox);

      while (my $msg = $folder->next_message()) {

          my $writer    = XML::SAX::Writer->new();
          my $filter    = XML::Filter::DataIndenter->new(Handler=>$writer);
          my $generator = XML::Generator::RFC822::RDF->new(Handler=>$filter);

          $generator->parse($msg);
      }

DESCRIPTION
    Generate RDF/XML SAX2 events for RFC822 messages.

    Messages are keyed using SHA1 digests of Message-IDs and email
    addresses. In the case of the latter this makes it easier to merge
    messages with contact data that has been serialized using
    XML::Generator::vCard::RDF (version 1.3+)
