I've posted the notes from Wednesday's class on Effective XML at SD Best Practices. I've been giving this talk for a few years now. It used to be I could assume that XML was the default choice for most applications. However, in 2007 there are some alternatives such as JSON for some use cases, so I added a new "Part O" that explained when competing formats were and were not appropriate; and why you might choose one over the other.
PowerPoint's XML export is truly hideous and incompatible with Firefox so I've used Openoffice Impress 2.3 to generate these. I see a number of issues I should file bugs on with OpenOffice, just as soon as they send me a password for the Bug tracker.
