Jeff Pollock has just released a book called Semantic Web for Dummies. Over at Semantic Universe you can download a free chapter (registration required), order the book, or read Jeff’s blog posts. I haven’t read the book yet, but Jeff is a really smart person with the ability to speak plainly and compellingly. This book is bound to be useful for people who are trying to understand the Semantic Web, or are still struggling with how to explain it to others. I just put my copy on order.
