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.
