RSS 1.0 also uses XML Namespaces, which make it possible to define extension modules such as WikiRssExtension. Finally, the RSS-Dev working group released RSS 1.0, basing this on the original RSS 0.9 - hence it uses RDF, not DTDs, and is not compatible with RSS 0.91/0.92/0.93.RSS 0.93 is also being defined by UserLand. Then, UserLand released RSS 0.92, based on 0.91 but without bothering with a formal DTD.A followup version, RSS 0.91, was renamed RichSiteSummary and switched to using XML DTDs (Document Type Descriptions) instead of RDF.The first RSS version, RSS 0.9, came from Netscape, was originally called 'RDF Site Summary' and was defined using XML and the standard RDF ( ResourceDescriptionFramework).Some history that clarifies things a bit, based on this article: There's an excellent article on RSS at - page 2 explains how XML, DTDs, RDF and XML Schemas are used in defining RSS. ![]() How RSS developed, and why RSS is not RDF
