RSS Created by Netscape in 1999. The first version is RSS 0.90. Followed by the RSS 0.91 version that has been improved by the Userland company in 2000.
In 2000 the version 1.0 based on RDF was created by O'Reilly and further maintained by the RSS-DEV group, and named RDF Site Summary.
RSS 2.0 was defined by Dave Winer (previously worker at Userland) at Harvard University in 2002.
This page is based on the Really Simple Syndication RSS, 2.01 specification from Harvard.
There are a number of different versions of the RSS format used today, but the popular verson which is used mainly are RSS 1.0 and RSS 2.0.
Each version has its benefits and drawbacks;
Both formats are XML-based and have the same basic structure.
- RSS 2.0 is more simple than RSS 1.0,
- RSS 1.0 is more extensible and fully specified than RSS 2.0.
RSS 1.0 uses XML Namespaces to allow extensions, in a similar manner to RSS 2.0.
RSS 1.0 ,RSS stands for RDF Site Summary. a Web standard for metadata. Because RSS 1.0 uses RDF, any RDF processor can understand RSS without knowing anything about it in particular. This allows syndicated feeds to easily become part of the Semantic Web.
In RSS 2.0, RSS stands for Really Simple Syndication and simplicity is its focus. This branch of RSS is based on RSS 0.91
