Metadata Markup

Now available: Cordes, Christopher Sean (2005) Creating HTML Meta-tags with the Dublin Core Element Set. Tutorial.
The breadth and scope of information available online and through intranets are making the standardization and use of metadata to identify records imperative if not mandated. Some measure of searchability is provided by the HTML meta tag <meta>, but the tag has limited potential for describing complex documents. The Dublin Core Metadata Initiative group has developed metadata standards that support a broad range of purposes and business models, most notably the Dublin Core Element Set. The set is fairly easy to learn, but must be combined with HTML if to provide metadata for referencing by a web crawler or search engine. This paper outlines the steps needed to create HTML metadata using the Dublin Core Element Set, and some of the benefits of doing so.
I don't think many search engines are now using any meta tags, except maybe description. However, as a tool for providing better searcing on your own site this is still of value.
