Atom is an XML-based document format that describes lists of related information known as feeds. Feeds are composed of a number of items, known as entries, each with an extensible set of attached metadata. For example, each entry has a title. The primary use for Atom format is the syndication of Web content such as weblogs and news headlines to Web sites, as well as publishing content directly to user agents.
The IBM® JAX-RS library provides two methods for consuming and producing Atom feeds and Atom entries in a JAX-RS application.
The first method is a JAXB Atom model that is included in the org.apache.wink.common.model.atom and org.apache.wink.common.model.synd Java packages in the Apache Wink-based IBM JAX-RS library JAR. An application can use classes such as a JAXB annotated org.apache.wink.common.model.atom.AtomFeed to read and write ATOM feeds.
You can also choose to use the Apache Abdera library, which is provided in the Feature Pack for Web 2.0, to implement Atom content for requests and responses.
You have developed and deployed a JAX-RS Web application on the application server that uses Atom content for requests and responses.
