An RSS file is written in XML (eXtensible Markup Language), so that each item in a list is coded with a unique tag. In turn, programs that read the XML can interpret each item correctly across many different platforms. This make RSS ideal for syndicating timely website content as headlines with links back to the originating site.

There are several versions of RSS files available. certcities.com complies with the RSS 2.0 standards as explained by "Technology at Harvard Law: RSS 2.0." Our files have been validated to RSS 2.0 and are also compatible with most earlier versions including RSS 0.91 released June 2000, RSS 0.92 (December 2000) and RSS 0.94 (August 2002). See RSS Resources below to learn more.

Programs that read valid RSS files are referred to as "aggregators." RSS clients that aggregate feeds are available for the desktop and from the Web. Many are free, some charge for the service. The intrepid can even design and build their own aggregator.A list of the more common RSS aggregators is given below.
