Atom/RSS Syndication

The Atom/RSS service is an example of a comprehensive Decentralized Software Services (DSS) service that handles a variety of topics including features such as

• Web-based UI using Extensible Stylesheet Language Transformations (XSLT)
• HTML form input and Uniform Resource Identifier (URI) queries
• Definition of complex state. The state of a service is an actual Atom feed document containing XML attributes, nested lists, etc.
• Handling of Decentralized Software Services Protocol (DSSP) operations such as INSERT, DELETE, and UPDATE
• DSSP subscriptions using the Subscription Manager (see System Services)
• Subscribing to other services

While many of these topics are covered in other service tutorials (see Service Tutorials Overview), in this tutorial we go through the various steps to cover these features in order to illustrate how to put together a complete service. This topic goes through the various parts of the Atom service implementation, please see Atom/RSS Service Overview for an introduction to the service.
