RSS: Usability Problems And Solutions
 By
Danny Wirken
RSS is a family of web-feed formats that is used for web syndication. It can also be used by news websites, weblogs and podcasting, among others.
The acronym can refer to various standards such as Really Simple Syndication (RSS 2.0), Rich Site Summary (RSS 0.91 and RSS 1.0) and the RDF Site Summary (RSS 0.9 and RSS 1.0).
RSS Backgrounder
Several similar formats already existed for syndication before RSS, but none were able to achieve widespread popularity or are still in common use today like it. This is primarily due to the fact that most were envisioned to work only within a single service. The RDF Site Summary which is the first version of RSS was created for use on the My Netscape portal. This eventually became known as RSS 0.9. A prototype that simplified the format and incorporated parts of a new scripting news format was produced in response to comments and suggestions made to the existing version. It was considered an interim measure as an RSS 1.0 like format was suggested through the so-called Futures Document.
The format was left without an owner when Netscape lost interest. Since it is becoming widely used, a working group and mailing list was set by various users and XML notables to continue its development. An RSS fork was created when two companies claimed ownership of the existing RSS.
A format grouped under an RSS 0.92 heading contained incremental changes to the existing format. Meanwhile, another group went on to produce RSS 1.0 which was based on RDF specifications but was more modular. When the RSS 0.92 was released, it contained minor and supposedly compatible set of changes to RSS 0.91. A subsequent draft was published for RSS 0.93 and RSS 0.94 by the same creator. RSS 0.93 was almost identical to 0.92 while the 0.94 reverted changes made in 0.93 and added a type attribute to the description element.
A final successor to the RSS 0.92 known as RSS 2.0 was released in September 2002 which emphasized "Really Simple Syndication" as the meaning of the three-letter acronym. It removed the type attribute added in RSS 0.94 and allowed users to add extension element using XML namespaces. Although several versions of it were released, the version number of the document model remained unchanged.
The adoption of the RSS format by New York Times became the starting point for such a format to becoming a standard. This format enabled it to offer its readers the ability to subscribe to RSS news feeds related to various topics. The RSS 2.0 specification was assigned ownership to Harvard's Berkman Center for the Internet and Society. The creation of the new format and the raising of the version number were criticized and were answered with the creation of RSS 3.0, which is a non-XML textual format. It was only intended as a parody and very few implementations were made.
