Developing Feeds with RSS and Atom

Introducing RSS 1.0

Now that we’re steeped in metadata and RDF syntax, it’s time to move on to RSS 1.0. This standard, released in December 2000, brought two major changes to the RSS world: the reintroduction of RDF and with it an introduction of namespaces .

Nowadays, of course, both flavors of RSS have namespaced modules. But only RSS 1.0 is in RDF. Example 5-4 shows what it looks like.
