"Resource Description Framework" a core technology for the "semantic web" defined by the W3C http://www.w3.org/RDF/ RDF graphs are used to represent metadata and the XML RDF syntax is widely used as a format to distribute, process and exchange metadata. RSS the nice XML vocabulary that many users apply to describe piece of news from their sites (content syndication) is indeed derived from RDF. So the parser can be used also to process RSS documents.
