This book was written with two somewhat interrelated groups in mind:

Web developers and web site authors: This book should be read by all web developers who want to share their site with others by offering RSS-based feeds of their content. This group includes everyone from bloggers and amateur journalists, to those running large-budget, multiuser sites. From multinational news organizations to neighborhood sports groups, the use of RSS can extend the reach, power, and utility of your product � this book shows you how.
Developers: This book is also for developers who want to use the content that other people are syndicating. This group includes everyone from fan-site developerss wanting the latest gaming news, or intranet builders needing up-to-date financial information on the corporate Web, to developers looking to incorporate news feeds into artificially intelligent systems or build data-sharing applications across platforms. For you, this book delves into the interpretation of metadata, different forms of content syndication, and the increasing use of web services technology in this field.
