RSS and Atom in Action is organized into two parts. The first part introduces the blog technologies of news feed formats and publishing protocols-the building blocks. The second part shows how to put to those blocks together to assemble interesting and useful blog applications. In keeping with the behind Manning's "In Action" series, this book shows the reader, through numerous examples in Java and C#, how to parse Atom and RSS format newsfeeds, how to generate valid newsfeeds and serve them efficiently, and how to automate blogging via web services based on the new Atom protocol and the older MetaWeblog API. The book also shows how to develop a complete blog client library that readers can use in their own applications. The second half of the book is devoted to a dozen blog apps-small but immediately useful example applications such as a community aggregator, a file distribution newsfeed, a blog cross-poster, an email-to-blog gateway, Ant tasks for blogging softwarebuilds, and more.
