A study on RSS - Part 2: The RSS format
In the last article I made a simple introduction to what is an RSS Feed and showed the path to creating XML files in PHP. Now itÂ’s time to explain the RSS file structure along with some basic history.
The RSS format was not the first to be used in site summaries, in 1997 the Channel Definition Format created by Microsoft showed up along other less know formats, but it wasnÂ’t until RSS that one specific format became largely popular and used by the Â“massesÂ”. The first RSS version, known as RDF Site Summary, was created by Dan Libby in 1999 to be used in NetscapeÂ’s portal. This format became known as RSS 0.9 and was followed by RSS 0.91, based on alteration proposed by public opinion.
