This session covers "collection indexing" or HTTP server directory listings with XML, and implications for Web applications. Attendees learn about mod_autoindex, W3C XHTML compliant collection index pages, XSL Transformations while maintaining backwards compatibility with deployed browsers, XLink, and other issues such as ISO8601 formatting of dates. The presentation culminates in a demonstration of a JavaScript1.1 implementation of the traditional hard drive explorer (that is, a "folder" tree on the left and a table view of resource properties on the right).
