I had someone today ask me what RSS was, especially since we have all seen RSS all over the ‘net in the last couple years. For anyone that doesn’t know, RSS is an acronym that stands for Really Simple Syndication, and it represents a standard format for sharing, or syndicating data. You create an XML file in this standard RSS format, that has the data in it you want to syndicate, then the client side can grab that file and process the data to display it on a web page or in a RSS reader or aggregator program.
Rather than re-invent the wheel so to speak, I’ll send you to Wikipedia for more information, they have a great writeup on RSS, and other similar formats past, present and future. In short, RSS is a great way to very easily syndicate or share data elements from one source to many destinations.
