RSS (Really Simple Syndication) is a format for web content syndication that allows users to subscribe to frequently updated information from websites. RSS uses XML files to deliver headlines, summaries, or full text content to users through an RSS reader in a standardized format. It benefits both publishers by letting them syndicate updated content easily and readers by subscribing to automatic updates from websites in one place.

1. About RSS
RSS is a Web content syndication format.
Its name is an acronym for Really Simple
Syndication.RSS is a dialect of XML. All RSS
files must conform to the XML 1.0
specification, as published on the World
Wide Web Consortium (W3C) website.

2. Introducing to How RSS Works
If you're addicted to the constant flow of data
that we know as the Internet, you're not going
to be able to manage it without some help. One
way to keep track of it all has grown very
popular since its introduction in 1997: RSS. Short
for Really Simple Syndication (at least now --
more on that later), RSS is a way to subscribe to
a source of information, such as a Web site, and
get brief updates delivered to you.

3. RSS Reader
Reading RSS feeds can be a great time-saver. In
the time it takes you to scan whole Web pages
for information, you can review headlines from
dozens of sites all collected in one place. On the
other hand, the ease with which you can view
RSS headlines may convince you that you can
subscribe to even more sites. You may end up
spending just as much time reading feeds as you
used to on regular Web sites.

4. Creating RSS Feeds
RSS isn't really that different from a normal
Web site. In fact, they're the same in one
respect: Both are simple text files on Web
servers. RSS uses the World Wide Web
Consortium's RDF as a guide to tell a feed
aggregator how to read the file. RDF is based on
XML , a cousin of HTML , which is the language
used for everyday Web sites.

5. Extending RSS
RSS originated in 1999, and has strived to be a
simple, easy to understand format, with
relatively modest goals. After it became a
popular format, developers wanted to extend it
using modules defined in namespaces, as
specified by the W3C. RSS 2.0 adds that
capability, following a simple rule. A RSS feed
may contain elements not described on this
page, only if those elements are defined in a
namespace.

6. Rss is a family of web feed formats
RSS is a family of web feed formats used to publish
frequently updated works—such as blog entries, news
headlines, audio, and video—in a standardized format. An
RSS document includes full or summarized text, plus
metadata such as publishing dates and authorship.
RSS feeds benefit publishers by letting them syndicate
content automatically. A standardized XML file format
allows the information to be published once and viewed
by many different programs. They benefit readers who
want to subscribe to timely updates from favorite
websites or to aggregate feeds from many sites into one
place.
