Especially for my wife, who as a former ontologist is more understanding and patient than most people could ever be with a semantics-obsessed husband. Without her love and support, this book would not have been possible. Author’s Acknowledgments Semantic Web is a passion for me. Without the inspiration of Tim Berners- Lee, Jim Hendler, Ora Lassila, Deb McGuinness, Ian Horrocks, and others like them, I would not have ever embraced this vision for the future. Without people like Nova Spivack, Mark Greaves, Eric Miller, and Dean Allemang con- stantly evangelizing and refi ning the way we all talk about the Semantic Web vision, I would not have been able to simplify and distill my own thoughts into a coherent whole. Finally, I owe very special thanks to Samir A. Batla and David Provost, whose contributions to several chapters in this book have made it a better work, more practical and more encompassing of the full scope of the Semantic Web. 01_396797-ffirs.indd v 01_396797-ffirs.indd v 2/13/09 6:42:23 PM 2/13/09 6:42:23 PM Publisher’s Acknowledgments We’re proud of this book; please send us your comments through our online registration form located at http://dummies.custhelp.com.
