RSS (Really Simple Syndication)

RSS (Really Simple Syndication) is a kind of description and synchronous web content format, is currently the most widely used XML application.

RSS is a originated from Netscape push technology, will subscribe subscriber content is transmitted to their communication collaborative format ( Protocol ).

Discussion and Blog related technologies, can not talk about RSS, the acronym in English can have several sources, and different technical groups do different interpretation. Can be both" Rich Site Summary", or" RDF Site Summary"," Really Simple Syndication can also be". Why are there so many meanings? This also from a RSS today there is no clear relationship.

Today there is still remember IE4 just pushed out when there is an interesting feature, that is the news channel. The news channel's function and Netscape launched a news channel is very similar ( Netscape was still the market leader in browser ). The Netscape defines a set of descriptions of news language, this is RSS, but Netscape since then go from bad to worse, so in the end did not release an official RSS specifications ( only released a version 0.9 ). While Microsoft was also launched in support of their IE CDF ( Channel Definition Format ) data specifications, and is similar to RSS. Microsoft tried to use news channel function of the" push" ( Push ) technology has become a mainstream, and Netscape. But beyond prediction is," push" technology from first to last did not find a suitable business model, and with other types of network characteristics, is unable to display its own advantages. News channel in the browser status eventually sunset Xishan, finally also in subsequent versions of IE disappeared.

News channel is entered trough, but the RSS has not been abandoned by industry professionals. Over the past two years, Blog from a professional groups in the beginning, gradually became the most popular new topic on the network. While RSS be described Blog theme and updated information about the most basic method. So this RSS technology is the famous Blogger / Geek Dave winner ( Dave Winner ), UserLand took over, continuing to develop new versions, to adapt to the new network applications require. A new network application is Blog, because Dave Wen that effort, RSS upgrade to version 0.91, and reached 0.92 edition, then in various Blog tools has been applied, and many professional news site support. In a wide range of applications, many professionals recognize the need to organize, the RSS become a generic specification, and further standardization. A joint group according to the W3C of a new generation of semantic web technology of RDF on RSS was redefined, released RSS 1, and RSS is defined as" RDF Site Summary". This work was not associated with Kevin Dave that communicate effectively, but Dave insisted on his own imagination direction on the further development of subsequent versions of the RSS, also does not recognize the validity of RSS 1. RSS began differentiation formed the RSS 0.9x / 2 and RSS 1 two camps, which also caused extensive debate in the professional groups.

Because of controversy over the existence, until today, RSS 1 has yet to become ISO standard. Dave winner in 2002 September alone the RSS upgrade to version 2, which by definition is completely new models, and no RSS 1 shadow. This caused further controversy whether the network, allowing a more universal data format into an open standard, or by a company to define and control, became the focus of controversy. Kevin Dave doesn't defended himself, his view is that RSS still needs further development, the need for professionals to be more clearly defined, but I'm afraid that touch on lightly not eliminate people on the RSS" was a commercial company exclusive" worry.

The front upholstery on the users may not too much significance, may be more concerned about how to in their own Blog increased RSS output, so that you can make a lot of news aggregation tools ( such as CNBlog just recommended NewzCrawler ) it is easy to find you and get your Blog automatic updates.
