I've posted the notes from last night's Native XML Databases presentation at the New York PHP User's Group monthly meeting. It was an active and inquiring audience, which is always fun; so we only got through the first 30 or so slides. I didn't really have time to go into the details of XQuery. There was also a tangent on REST and proper URL and web application design, we couldn't really explore fully. Maybe next time.
If anyone's interested in having me deliver this talk to their user group or conference, drop me a line. I don't have much time for out of town travel right now, but I can usually arrange something in New York City and its immediate vicinity.
