      • RSS is divided into two parts:
        • Feeds
        • Aggregators(A software program that you can download and then use to read your RSS feeds)
      • Tested clients:
        • Local Readers (browser and stand alone readers)
        • Web based readers
    • How to find RSS feeds?
      • Look for a button like these within a site:
    • Consuming RSS
      • All tools have common traits
        • Access RSS Feeds
        • Track what a user has already read
        • Reproduce feed content
        • Link to original source
    • Current Scenario
    • Advantages of RSS
      • You can read feeds from multiple websites in one location.
      • No SPAM!
      • No Pop-Ups!
      • Most blogs now have feeds, and more journals and news sites are adding them.
    • Disadvantages
      • Some users prefer email updates over an RSS feed.
      • Graphics and photos do not appear in all RSS feeds.
      • Publishers cannot determine how many users are subscribed to their feed and the frequency of their visits.
      • Higher traffic and demands on the server.
      • Since it is a new technology, many sites still do not support RSS.
    • Bake it From Scratch
      • Declare the RSS version you’re using (2.0 is the latest) with the <rss> tag
      • Use the <channel> tag to begin your feed
      • Use the <title>, <description>, and <link> tags to describe your feed as a whole (there are other optional tags that apply to your feed as a whole, like <copyright>, <image>, and <webMaster>)
      • Start each item with the <item> tag
    • Bake it From Scratch
      • Within each item, add a <title>, <description>, and <link>
      • End each item with </item>
      • End your feed with </channel>
      • End your file with </rss>
      • Save your files as an XML file (eg. sciencenews.xml)
    • What does it look like?
    • That’s it! Now upload your .xml file to your server and subscribe to your feed using your feed reader.
