NAME

HTML::DublinCore - Extract Dublin Core metadata from HTML

SYNOPSIS

  use HTML::DublinCore;

  ## pass HTML to constructor
  my $dc = HTML::DublinCore->new( $html );

  ## get the title element and print it's content
  my $title = $dc->element( 'Title' );
  print "title: ", $title->content(), "\n";

  ## get the same title content in one step
  print "title: ", $dc->element( 'Title' )->content(), "\n";

  ## list context will retrieve all of a particular element 
  foreach my $element ( $dc->element( 'Creator' ) ) {
      print "creator: ",$element->content(),"\n";
  }

  ## qualified dublin core
  my $creation = $dc->element( 'Date.created' )->content();

DESCRIPTION

HTML::DublinCore is a module for easily extracting Dublin Core metadata that is embedded in HTML documents. The Dublin Core is a small set of metadata elements for describing information resources. Dublin Core is typically stored in the <HEAD> of and HTML document using the <META> tag. For more information on embedding DublinCore in HTML see RFC 2731 http://www.ietf.org/rfc/rfc2731. For a definition of the meaning of various Dublin Core elements please see http://www.dublincore.org/documents/dces/.

HTML::DublinCore actually extends Brian Cassidy's excellent DublinCore::Record framework by adding some asHTML() methods, and a new constructor.

METHODS

new()

Constructor which you pass HTML content.

    $dc = HTML::DublinCore->new( $html );

asHtml()

Serialize your Dublin Core metadata as HTML <META> tags.

    print $dc->asHtml();

TODO

  • More comprehensive tests.

  • Handle HTML entities properly.

  • Collect error messages so they can be reported out of the object.
