RSS (Rich Site Summary); originally RDF (Resource Description Framework) Site Summary; often nicknamed Really Simple Syndication, uses a family of web feed formats standard to publish frequently updated information: blog entries, news headlines, audio, and video. An RSS document (called "feed", "web feed", or "channel") includes full or summarised text, and metadata, such as the date of publication and the name of the author.
What is RSS Feed
RSS feeds allow you to publishers syndicate data automatically. An XML file format standard ensures compatibility with many different machines / programs. RSS feeds also benefit users who want to receive the timely updates of your favourite web pages or to add data from many sites.
Why subscribe to an RSS Feed
Subscribing to an RSS feed eliminates the need for the user to manually check the website for the new content. On the other hand, your browser constantly monitors the website feed and informs the user of the updates. The RSS browser can also be ordered to automatically download the new data for the user.
What is RSS Software
Software called "RSS reader", "RSS aggregator" or "feed reader", which can be desktop based or on mobile devices, present data based RSS web users. Users subscribe to the RSS feeds or by entering the URI of a feed on the reader or by clicking on the RSS icon of the browser. The RSS reader checks the user feeds regularly for new information and you can download automatically, if this function is enabled. The RSS reader also provides a user interface.
The RSS formats were preceded by several attempts to organise website syndication that did not achieve great popularity. The basic idea of the restructuring of the information about websites dates right back to as early as 1995, when Ramanathan Guha and others in Apple's Advanced Technology Group Computer developed the Metal Content Framework.
RDF Site Summary, the first version of RSS was created by Dan Libby and Ramanathan Guha in Netscape. It was launched in March 1999, for use in the portal My.Netscape.Com. This version became known as RSS 0.9. In July of 1999, Dan Libby of Netscape produced a new version, RSS 0.91, which simplifies the format through the elimination of RDF elements and the incorporation of elements from syndication format of news from Dave Winer. Libby also change the name of the format of RDF to RSS Rich Site Summary and outline a further development of the format in a "document of future".
This would be the last participation in the Netscape RSS development for eight years. As an RSS feed was being embraced by the web publishers who wanted their food to be used in My.Netscape.Com portals and other early RSS, Netscape abandoned the My.Netscape.Com RSS support in April 2001 during the restructuring of the new owner of the company AOL, also remove documentation and tools that support the format.
Two entities emerged to fill the vacuum, with the assistance or approval of Netscape: The Working Group RSS-DEV and Dave Winer, whose Software userl had published some of the first publication tools outside of Netscape who could read and write RSS.
Winer published a modified version of the RSS 0.91 specification in the userl web page, which covers the way in which it is used in the products of your company, and claim the right to author with the document. A few months later, userl introduced the registration of a mark of USA for RSS, but has not responded to the request for a Trade Mark examiner of the USPTO and the request was rejected in December of 2001.
The RSS-DEV Working Group, a project whose members included Guha and representatives of O'Reilly Media and another part, produced RSS 1.0 in December 2000. This new version, which regained the name of RDF Site Summary of RSS 0.9, reintroduced the support for RDF and added support for XML namespaces, taking elements of metadata vocabularies such as Dublin Core standard.
In December 2000, Winer released RSS 0.92 a smaller set of changes, apart from the introduction of the housing element, which allowed the audio files to be carried in the RSS feeds and podcasting helped spark. He also published the draft RSS 0.93 and RSS 0.94 that were subsequently withdrawn.
In September 2002, Winer released a new version of the format and important, RSS 2.0 , that redubbed its acronym for Really Simple Syndication. RSS 2.0 removed the attribute of aggregate type in RSS 0.94 project and has added support for namespaces. To preserve backward compatibility with RSS 0.92, support of namespace applies only to another type of content included within a channel RSS 2.0, RSS 2.0 and not the elements themselves. (Although other standards such as Atom attempt to correct this limitation, the RSS feeds are not added with other types of content often enough to move the popularity of RSS to other formats with support of full namespace.)
Due to the fact that neither Winer nor the Working Group of RSS-DEV had the participation of Netscape, could not make a formal complaint on behalf of RSS or format. This has fuelled the dispute in progress in the development community of unionisation in regard to that entity was the appropriate editor of RSS.
One of the products of this controversial debate was the creation of an alternative syndication format, Atom, which began in June 2003. The Atom syndication format, whose creation was motivated in part by the desire to obtain a clean outlet free of the issues surrounding RSS, it has been adopted as standard Proposed IETF RFC 4287.
In July 2003, Winer and userl Software assigned the rights of the author of the RSS 2.0 specification to the Harvard Berkman Center for Internet and Society, which had just started a period as visiting professor. At the same time, Winer launched the RSS Advisory Board with Brent Simmons and Jon Udell, a group whose objective was to maintain and publish the specifications and answer questions about the format.
What is the RSS icon
In September 2004, Stephen Horlander created the RSS icon now ubiquitous (Feed-icon.svg) for use in the Mozilla Firefox browser.
In December 2005, the team of Microsoft Internet Explorer and the Microsoft Outlook team announced on his blog that they were taking RSS icon in Firefox. In February 2006, Opera Software has done the same thing. This made effective the orange square with waves of white radio the industrial standard for RSS and Atom feeds, in replacement of the wide variety of icons and text that had been used previously to identify data to organise.
In January 2006, Rogers Cadenhead has relaunched the Advisory Board of RSS without the participation of Dave Winer, with a government's desire to continue with the development of the RSS format and resolve ambiguities. In June 2007, the Council revised its version of the specification to confirm that the namespaces can be extended the basic elements with the namespace attributes, because Microsoft has done in Internet Explorer 7. In his opinion, a difference of interpretation left publishers unsure if this was allowed or prohibited.
What does an RSS feed look like
Here is an example of an actual RSS feed from Facebook:
