How It All Fits Together

Mike Schroepfer posted a diagram showing the Mozilla Platform and its building parts. The lower levels have mostly been in use for years, only Cairo/Thebes and SQLite are quite new. The top level, Toolkit, is the way where Suiterunner is going. The only things I don't know about (when it comes to SeaMonkey) are Widget and XBL. And, as you might notice, RDF is missing. It's probably deprecated and not widely used nowadays, especially in Toolkit applications.
