Jason Hunter is co-founder of the JDOM project, proprietor of servlets.com and xquery.com, and author of the classic book Java Servlet Programming. Nowadays Jason works with Mark Logic, whose Content Interaction Server (CIS) marries fulltext search with XQuery-based XML search and transformation. In today's screencast, Jason shows me some of the things he can do with a corpus of O'Reilly book content, using the Mark Logic CIS as a combined XQuery engine and Web application server.
Because a lot of people said my Wikipedia screencast was long at 8.5 minutes (though worthwhile), I've edited this one down to about twelve minutes. It's not a demonstration of the Mark Logic product per se, but rather a tutorial that focuses on XQuery itself. If you've been looking for a way to get a handle on XQuery, this will be a good place to start.
Meanwhile, I've installed the Mark Logic server, and when I get a bit farther along I plan to use it to offer structured search of my own weblog and of the blogs I read. What I can tell you so far agrees with what Jason told me. This engine loads XML content really fast, indexes as it loads, and makes it easy to start writing CGI-style XQuery scripts.
