What is RSS?
RSS, which stands for RDF Site Summary, but often referred to as Really Simple Syndication, is a tool for
condensing information into a feed, which can then be downloaded
automatically as new information becomes available. It
is a computer-generated data-file format that sites use to communicate
their contents to other sites and applications. Using a really simple
definition structure, (thus the name), RSS makes it easy for developers
to extract and integrate data from other sources into their own (J.
Spool). Typically
sites that change or add content regularly provide RSS feeds to save
users the trouble of having to visit the site and check for anything
new.
At a technical level, RSS is a file format as well as the process for
converting things to that format and distributing them. This technology
allows you to “subscribe” to any source (website, weblog, database,
etc.) that provides an RSS feed. To subscribe to a feed you use a piece
of software called an “aggregator.” Aggregators will soon be built into
all browsers but they can also be integrated with email programs like
Outlook. The aggregator acts as a personal mailbox receiving items -
articles, podcasts, etc. - from the feeds to which you subscribe.
