SitemapsUntil recently, sitemaps were hand-drawn or script-drawn tree diagrams.
Now browsers that support eXtensible markup language (XML) offer more elaborate
sitemaps as a special feature. The newer sitemaps provide a hierarchical
description of a site, written in the resource
description framework (RDF), an XML application still being developed as a
standard by the World Wide Web Consortium. For example, Netscape's Mozilla
finds RDF sitemaps by looking for <LINK rel=sitemap> tags in your
Web pages. This tag tells Mozilla to open the sitemap and then render the
site diagram as part of the graphical display of the user agent. While
sitemaps themselves may not be the niftiest things in the world, they do
occupy a noteworthy position on the Web's timeline as one of the first
implementations of RDF.
