This book is relevant to all those who suspect "WWW" stands for "World Wide Wait." If you don't understand the Internet's shortcomings, just type "antidisestablishmentarianism" into the Google search engine and try to make sense of the 5,890 returns you get. Currently, there are three billion pages of information on the Internet, but within the next year that number will double. The question is how to manage the data while still increasing the functionality of the Web, continuing its transformation from a place where you "find something" to a place where you "do something." To accomplish those tasks, you have to go beyond "meta-tags" - those invisible headlines that tell search engines what any given page is really all about. This volume outlines the Semantic Web approach, which offers answers to those questions. A word of warning: this somewhat technical book will be of greatest interest to programmers, Web designers, specialists and motivated visionaries. We recommend it highly - if you fit into one of those categories.
