Re: Rss Feed ?
RSS stands for Really Simple Syndication. It was originally conceived as a
method for a website to publish a list of headlines, with links back to
their own site; this list would then be picked up by *other* websites.
So without RSS, I could link to your website like this:
<p>Here is <a href="http://example.com ">Piyush's Website</a>.</p>
But with RSS, my website could check your RSS file on a daily (or even
an hourly) basis and build up a list of recent news stories on your
<h2>Latest News from Piyush</h2>
<li><a href="http://example.com/news/006 ">Hello Saturn</a>
<li><a href="http://example.com/news/005 ">Hello Jupiter</a>
<li><a href="http://example.com/news/004 ">Hello Mars</a>
<li><a href="http://example.com/news/003 ">Hello World</a>
As well as this original intention of RSS, some people will now subscribe
to RSS feeds on their own computer. That is, originally RSS was used to
send information from one website to another, like this:
Website ===[RSS]===> Website
and now it is also used like this:
Website ===[RSS]===> Visitor
to send information to any visitors who have subscribed to your RSS feed.
Here is an example RSS file with two stories:
<!DOCTYPE rss SYSTEM
<description>The website of Piyush</description>
<description>Saturn has many rings and
<description>Jupiter is a big ball of gas.</description>
RSS is suitable for websites which have new content added frequently, such
as news websites, weblogs and fora.
XML Sitemaps are another technology used like this:
Website ===[XML Sitemap]===> Website
The information that is shared is completely different though. XML
Sitemaps contain a list of pages at a website, along with some information
about when those pages were last updated; and how often the site publisher
thinks that search engines should wait between re-visiting the page. Here
is an example:
<?xml version="1.0" encoding="UTF-8"?>
Unless you require very fine control over how often your website is
visited by search engine robots, and which pages they view, then it's
unlikely that one of these will be much use to you.
