"Other books claim to present the complete Web services platform architecture, but this is the first one I've seen that really does. The authors have been intimately involved in the creation of the architecture. Who better to write this book?" - Anne Thomas Manes, Vice President and Research Director, Burton Group

"This is a very important book, providing a lot of technical detail and background that very few (if any) other books will be able to provide. The list of authors includes some of the top experts in the various specifications covered, and they have done an excellent job explaining the background motivation for and pertinent details of each specification. The benefit of their perspectives and collective expertise alone make the book worth reading." - Eric Newcomer, CTO, IONA Technologies
