| |
| |
| <p>RSS (Really Simple Syndication) is an XML-based document format for the syndication of web content such as weblogs and news headlines to Web sites as well as directly to user agents. Apache Wink supports the RSS 2.0 specification.</p> |

| |
| <p>Apache Wink provides an RSS data model for consuming and producing RSS Feeds (application/xml). All of the model classes are located under <b>org.apache.wink.common.model.rss</b> package.</p> |
