Gosh. There sure are a lot of things that go by those initials, if acronymfinder.com is any judge. I'm assuming you're not talking about anything to do with radar, though, which knocks a lot of the contenders out of the running.

I'll assume you're talking about "Really Simple Syndication" (although "RDF Site Summary" also looks promising), not that I know what that does apart from the obvious. What does it do?
