The DAML (The DARPA Agent Markup Language Homepage ) site has a nice variation on the usual site map – the new user roadmap. They list some of the primary users:

• software developer
• XML enthusiast
• logician
• WWW standards junkie
• program manager
• Semantic Web researcher
• military user
• reporter

and each is a link to a set of pages for that user type to explore in order to learn about DAML:

And since these are metadata folks, I wouldn’t be surprised if these categories are populated dynamically using metadata.
