    • 1. WHAT IS RSS? by: Sarah Collins
    • 2. RSS RSS formerly known as Rich Site Summery now stands for Really Simple Syndiction. RSS is an XML-based format for content distribution especially for delivering updates to websites for things such as headlines or video feeds in a standardized format. It it most frequently used on news-based sites due to the constant changing of events and web blogging sites.
    • 3. Versions of RSS There are several different versions of RSS falling into two branches. The first being RDF and the other being 2.* The RDF branch includes: RSS 0.90 was the original Netscape RSS version. This RSS was called RDF Site Summary, but was based on an early working draft of the RDF standard, and was not compatible with the final RDF Recommendation. RSS 1.0 is an open format by the RSS-DEV Working Group, again standing for RDF Site Summary. RSS 1.0 is an RDF format like RSS 0.90, but not fully compatible with it, since 1.0 is based on the final RDF 1.0 Recommendation. RSS 1.1 is also an open format and is intended to update and replace RSS 1.0. The specification is an independent draft not supported or endorsed in any way by the RSS-Dev Working Group or any other organization.
    • 4. Versions (cont.) The RSS 2.* branch includes: RSS 0.91 is the simplified RSS version released by Netscape, and also the version number of the simplified version originally championed by Dave Winer from Userland Software. The Netscape version was now called Rich Site Summary; this was no longer an RDF format, but was relatively easy to use. RSS 0.92 through 0.94 are expansions of the RSS 0.91 format, which are mostly compatible with each other and with Winer's version of RSS 0.91, but are not compatible with RSS 0.90. RSS 2.0.1 has the internal version number 2.0. RSS 2.0.1 was proclaimed to be "frozen", but still updated shortly after release without changing the version number. RSS now stood for Rea"y Simple Syndication. The major change in this version is an explicit extension mechanism using XML namespaces.
    • 5. Benefits of RSS RSS solves a problem for people who regularly use the web. They benefit readers who want to subscribe to timely updates from favored websites or to aggregate feeds from many sites into one place. It allows you to easily stay informed by retrieving the latest content from the sites you are interested in. You save time by not needing to visit each site individually. You ensure your privacy, by not needing to join each site's email newsletter. The number of sites offering RSS feeds is growing rapidly and includes big names like Yahoo News.

    • 7. Hosting and Some Down Sides to RSS Many marketers want to know how many subscribers they have, which items in their feeds attract the most interest, or how many click-throughs are generated as a result of an RSS feed. The most common method to track the number of feed accesses or individuals accessing a feed is to use a 3rd party feed host. Companies like FeedBurner essentially track feeds based on accesses. The downside to using a 3rd party like Feedburner, is that the url is a FeedBurner url and any PageRank or popularity associated with the url will benefit the feed host rather than the feed creator. Additionally, no distinction is made between unique views or syndicate feeds.
