This presentation describes a project completed at Verio, Inc. to create a brandable, scalable web hosting application platform for the use of Verio clients and resellers. Using a distributed, Perl daemon that sends and receives XML, a Java XSLT engine running under Apache Jakarta, and a hierarchical database of XSL/XML branding data, the applications group at Verio has created a framework that allows resellers to independently deploy custom applications that get distributed across servers.

The presentation will cover the following points:

• Why Perl *is* a language of choice for event-driven XML applications
• How a meta-language can describe application logic independent of code
• How everyone benefits by complete separation of content, display, and app logic elements

The presentation is of interest to anyone involved in the development of large applications, especially within web hosting environments.
