(via Simon Dückert auf Mastodon und en.wikipedia.org/wiki/RSS):
“RDF Site Summary, the first version of RSS, was created by Dan Libby and Ramanathan V. Guha at Netscape. It was released in March 1999 for use on the My.Netscape.Com portal.[8] This version became known as RSS 0.9.[5] In July 1999, Dan Libby of Netscape produced a new version, RSS 0.91,[3] which simplified the format by removing RDF elements and incorporating elements from Dave Winer’s news syndication format.[9] Libby also renamed the format from RDF to RSS Rich Site Summary and outlined further development of the format in a “futures document”.[10]”
