Developing Feeds with RSS and Atom

Name

mod_rss091

Synopsis

The mod_rss091 module is designed to give RSS 1.0 “sideways compatibility” with RSS 0.91. Because the three core subelements of the item element are the same in both standards, including mod_rss091 elements in your RSS 1.0 feed allows for dynamic downgrading of the feed for parsers that can’t be bothered with all the RDF stuff. Because the data is rather simple and mostly static, including this module within your RSS 1.0 feed is straightforward. With this in mind, it’s worth doing.

Namespace

The prefix for this module is the self-explanatory rss091:, and the module is represented by the URI http://purl.org/rss/1.0/modules/rss091#. Hence:
