# RSS History * * * Many different versions of RSS have been released. * * * ## The History of RSS ## The History of RSS * **1997** - Dave Winer developed scriptingNews. RSS was born from this. * **1999** - Netscape developed RSS 0.90 (supported by scriptingNews). This was a simple XML with an RDF header. * **1999** - Dave Winer at UserLand developed scriptingNews 2.0b1 (which incorporated features specific to Netscape's RSS 0.90). * **1999** - Netscape developed RSS 0.91. In this version, they removed the RDF header but included most features from scriptingNews 2.0b1. * **1999** - UserLand abandoned scriptingNews and adopted RSS 0.91 exclusively. * Netscape discontinued RSS development * **2000** - UserLand released the official 0.91 specification * **2000** - A team led by Rael Dornfest at O'Reilly developed RSS 1.0. This format used RDF and namespaces. This version is often confused with a new version of 0.91, but it is an entirely independent format unrelated to RSS 0.91. * **2000** - Dave Winer at UserLand developed RSS 0.92. * **2002** - After leaving UserLand, Dave Winer developed RSS 2.0. * **2003** - The official RSS 2.0 specification was released. * * * ## Where Are the Differences? RSS 1.0 is the only version developed using the W3C RDF (Resource Description Framework) standard. The concept behind RDF is to help build a semantic web. (#). Although this has little relevance for ordinary users, data exchange becomes easier for individuals and applications through the use of web standards. * * * ## Which RSS Version Should I Use? RSS 0.91 and RSS 2.0 are easier to understand than RSS 1.0. Our tutorial is based on RSS 2.0. * * * ## Is There an Official Web Standard for RSS? No official standard exists for RSS. * Approximately 50% of all RSS feeds use RSS 0.91. * Approximately 25% use RSS 1.0. * The remaining 25% use either RSS 0.9x versions or RSS 2.0.
