Developers,

I've completed a new version of my MQL tutorial, and have made it available, in PDF form, here: http://www.davidflanagan.com/Metaweb/mqltutorial.pdf

This new version is better organized and more complete than the one that is currently available in HTML on freebase.com. New material includes coverage of these MQL features:

- link queries - reflective queries - history queries - the != operator an optional:forbidden directive - enumerations - the ! property prefix - the return:count directive

I'm posting this updated chapter before I update the rest of the book because there is so much new material in it. I hope you find it useful. Your feedback on this draft is most welcome. Please note that the tutorial is Copyright (c) 2008 by Metaweb Technologies, Inc.
