Really Simple Syndication
The first version of RSS was called RDF Site Summary. It was made by Dan Libby and Ramanathan V. Guha at Netscape and made public in March 1999. This became RSS 0.9. In July 1999, RSS 0.91 was created by Dan Libby,  which got rid of some features that weren't useful. It also added elements from Dave Winer's news syndication format. Libby renamed the format from RDF to RSS Rich Site Summary and planned how it should be made better in the future.
