Preface

This book is about RSS, the massively popular content-syndication technology. From distributing headlines across web sites and delivering complete content to specialist applications, to providing the building blocks of the Semantic Web, RSS is one of the Internet’s fastest growing technologies.

There are over one million RSS feeds available across the Web; this book shows you how to read them and how to create your own. This book covers:

Extending RSS through modules
RDF and the Semantic Web
Web-based aggregators
Desktop readers
Publish and Subscribe
