Found an interesting tutorial on Overview of UML from IBM Rational Software. It briefs about software modeling, model-driven development, MDA, UML requirements, philosophy, and structure. Highly recommended for beginners and explained in simple terms. You can download the .ppt file from HERE!.
Great blog and a nerd score of 99! ;-) Awesome buddy!
Though I've good enough idea of UML, I'd like to go through the tutorial you posted. Could you please post it some file format that is accessible easily on all platforms? In my case (and almost all cases) 'pdf' would do.
