What does RSS 2.0 Support Right Out of the Box?

Welcome back to our short series on presenting RSS and Syndication for the beginner. In today's article I'm going to talk a bit 'of RSS in its current format version 2.0. RSS has a long history of change from both programming languages ​​for XML, RDF and RDF back and now back to XML. The reason for this is rather simple.

RSS was originally developed under the RDF, which is a little 'how to HTML. And 'basic and direct, but you can only use tags that are pre-programmed by the developer original language. Because of this, RDF has become the limiting factor for the development RSS. XML was later commuted because it allowed developers to create and use their own tags to facilitate the growing demand from developers. Later in version 1.0, RSS, RDF is returned to the picture that was previously used in version 0.90. This time RSS had 3 main modules to work with to facilitate the needs of the developers were trying otherwise.

This time in the RSS version 2.0 had 3 tags unique. They are:

A tag for the date of publication. This was really important for blogging as some blogs are not updated for a period of time, while others are constantly updated.

A "guid" or Global Unique Identifier is now included in the RSS 2.0 The "guid" RSS readers allowed to redisplay objects if their names or other information related to the changes.

Version 2.0 also supports namespaces. An XML namespace is a feature that allows the user to refer to a URL that specifies the standards that you want to use. These namespaces allow developers to add advanced functionality to the RSS feed including things like the formatting options.
