ROME: RSS and Atom Utilities
"...ending syndication feed confusion by supporting all of 'em. " *

ROME is a set of Atom/RSS Java utilities that make it easy to work in Java with most syndication formats:

• RSS 0.90
• RSS 0.91 Netscape
• RSS 0.91 Userland
• RSS 0.92
• RSS 0.93
• RSS 0.94
• RSS 1.0
• RSS 2.0
• Atom 0.3
• Atom 1.0

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.

If you use ROME for your site or software, please add it to the wiki page PoweredByRome, or drop us an email.
