RSS is a way of syndicating content published on a web site. The idea is
really no different to no different to traditional news syndication. For
example in the world of newspapers Cambridge Evening News take stories
from the Press Association and Reuters and publish them in their paper
as CEN stories.
RSS does the same thing for the web. Web sites that want to syndicate
their content, which is typically either online news sites like The
Register or Milton Village or the County Council press office, to take
some examples I'm familiar with, or individual's blogs (essentially
people's online diaries) provide the content as an RSS feed.
The RSS feed contains information about the news source (who owns it, a
short and long description, the editor's email address, that sort of
thing) and it contains the most recent articles published on the web
site. For each article you get the headline, some or all of the content,
a URL to the actual page where the original article can be found, the
date published and other optional fields.
So that's the "Press Association" end of things: the syndication. But
the RSS feed is raw data. Think of it as being like a teletype in an old
style newpaper office spitting out stories in capital letters on a long
ribbon of paper. To make use of it you need to do something with that
data. Cambridge Evening News typeset it to produce their paper. So the
content doesn't change but the way it looks does.
With RSS it's much the same - there are a wide variety of applications
that take the RSS and do stuff with it to make it presentable. They also
let you combine lots of RSS feeds to that you get news from lots of
places presented to you in one interface.
Here's two examples:
1. There's a web site www.bloglines.com - sign up to that (it's
free) and you can build up a set of RSS feeds. Every time you visit
you click on "My Feeds" and it shows you a list of all the new
stories from your feeds. Click on a link and you can go to the full
story on the original web site.
2. I have a program called KNewsTicker on my desktop (it's a Linux
program but there's similar programs around for Windows). If I have
that running it shows the latest headlines from a selection of news
feeds of my choosing which scroll across the screen in a long thin
window. If a story catches my eye I click on the headline and it
opens my web browser on the right page on the original web site.
Some web sites use it to show news as part of their other content -
"latest headlines from XXXXX" they'll say - that will probably be via an
RSS feed.
And it's also used for things other than news and blogs. For example I
use a Linux distribution called Gentoo. Every day new software is
released and they use RSS as one way of letting people know what's been
released - every release results in an RSS article being published.
> And lets stop all this (I know more than you do ) attitude please.
Hey, we do - or else you wouldn't be asking ;-)
Anyway I hope the above helps. In truth I knew very little about RSS
either other than in the broadest terms until I took on this project -
it's been fascinating to learn more.
If you want to know more about RSS 2.0, which is the version we use,
then the place to go is what is effectively its homepage
blogs.law.harvard.edu/tech/rss
where there's a good overview and lots of links as well as examples of
feeds from other places.
