The book is about 15% done (about 50 pages so far) and a rough draft PDF file is available. I realize that the market for this book will be small because AllegroGraph is a commercial product.

This book is fairly easy for me to write because I have existing coding experiments for just about all the Semantic Web application examples in the book. Also, since there are so many good Semantic Web references on the web and in existing books, I am only covering the SW technology that is used in the book examples. I want the book to be self contained: just enough tutorial and reference material covering AllegroGraph and other SW technologies so readers can completely understand the application examples.
