ROME is a Java framework for RSS and Atom feeds. It's open source and licensed under the Apache 2.0 license.

ROME includes a set of parsers and generators for the various flavors of syndication feeds, as well as converters to convert from one format to another. The parsers can give you back Java objects that are either specific for the format you want to work with, or a generic normalized SyndFeed class that lets you work on with the data without bothering about the incoming or outgoing feed type.
