What are the differences?

RSS 1.0 is the only version developed using the W3C's RDF (Resource Description Framework) standard.

The idea embodied in RDF is to help build a semantic web.Read more about RDF and the Semantic Web here. Although this has little to do with ordinary users, the use of web standards makes data exchange easier for individuals and applications.
