The following is an official introduction to RSS:
First, what is RSS?
Maybe everyone is the first time I heard the concept of RSS, what is RSS? RSS is an easy way (also called aggregated content), usually used in news and other websites, such as BLOG. The introduction of a project may contain all the introduction of the news. Or just additional content or short introduction. The links of these items are usually linked to all content. Network users can read the website content that supports RSS output without opening the website content page with the client's news aggregation tool software that supports RSS.
To be more simple, RSS is an XML format used to distribute and bring web content! If you still don't quite understand, there is no relationship, and RSS is in fact, it is not important. It is important that RSS can do. Let's take a look, RSS can bring us?
Small Knowledge Blog: Blog is a referusion of web logg. In China, people usually call it a blog. It is an intermediary with readers to interact with a diary style. In the software community, people have become more popular with the blog form and thoughts, and people began to learn from each other in the form of blogs. The blog has become a place of technology exchange! Such as: http://blogs.msdn.com is a blogging on the MSDN. And China's blog China is also more famous. Http://www.blogchina.com.
XML: XML is an extensible Markup Language, an extensibility identifier language.
Second, the history of RSS
So what is RSS? There are two kinds of sayings, one is "Rich Site Summary" or "RDF Site Summary", and the other is "Really Simple Syndication", and these differences need to be said from the history of RSS development. The initial 0.90 version RSS is designed by Netscape, the purpose is to build a portal integrating the main news site content, but the 0.90 version of the RSS specification is too complicated, and a simplified RSS 0.91 version also has Netscape Company The abandonment of the project was suspended in 2000.
Soon, a company specially engaged in blog writing software has taken over the development of RSS 0.91, and continues to develop it as one of its blog writing software, and gradually launches 0.92,0.93 and 0.94 versions. With the popularity of the network blog, RSS is also supported by more and more websites and blog software.
While Userland is handling and continuously developing RSS, many professionals recognize the need to develop RSS into a general specification through a third party, non-commercial organization, and further standardize. So, in 2001, a joint group was based on the development of the 0.90 version of RSS. Based on the W3C's new generation of Semantic Network Technology RDF (Resource Description Framework), RSS1.0 is redefined, and RSS1.0 is released, and RSS is defined as " RDF Site Summary. However, this work does not have effective communication with Userland, and Userland does not recognize the effectiveness of RSS 1.0, and adheres to the subsequent version of RSS in accordance with its own ideas, and released the latest version of RSS 2.0 in September 2002. Userland defines RSS as "Really Simple Syndication".
At present, RSS has differentiated into RSS 0.9x / 2.0 and RSS 1.0 two camps. Due to the existence of differences and the current extensive application of RSS 0.9x / 2.0, RSS 1.0 has not become the true standard of standardized organizations. Third, what can RSS do?
1. Subscribe to Blog (on Blog, you can subscribe to the technical articles you need in your work; you can also subscribe to the author's logs with you with the author of the author. In short, what is your interested in blog you can order? 2. Subscribe to the news (whether you have a strange thing, star news, sportswear, as long as you want to know, you can subscribe)
You don't have a website, a web page, a web page. As long as this will subscribe you need to subscribe in an RSS reader, you will automatically appear in your reader, you don't have to refresh the webpage for a news that is eager to know, because once there is an update, RSS Readers will notify you yourself!
Third, RSS reader
Currently, the RSS reader can be basically divided into two categories.
The first class most readers are single-machine applications running on the computer desktop, which can be updated automatically and timedically through the news supplies in the subscribers and blogs (Blog). In this reading, there are free trials and paid advanced editions, in addition, Xinhuanet has also launched an RSS reader without long ago. It is completely a Chinese interface, and is currently completely free! (After we will use this software as an example, let you introduce how to use the RSS reader)
The second type of news reader is usually in an application that is embedded in an application that has been run in your computer. For example, Newsgator is embedded in Microsoft's Outlook, and the subsequent news header is located in the Outlook's inbox folder. In addition, PLUCK is embedded in the Internet Explorer browser!
Fourth, the Syndication and aggregation (AGGREGATION)
After publishing an RSS file (generally referred to as RSS feed), the information contained in this RSS feed can be called directly by other sites, and since these data are standard XML formats, they can also be used in other terminals and services. Such as PDAs, mobile phones, mailing lists, etc. And a website alliance (such as a website series specially discussed) can also call each other's RSS feed, automatic display of the latest information on other sites in the website alliance, which is called the Joint of RSS. This combination causes the content update of a site to the more time, the more the RSS feed is called, the higher the visibility of the site, thereby forming a benign loop.
The so-called RSS aggregation is to collect various RSS feeds from the network through the method of software tools and provide readers in an interface. These software can be online web tools such as http://my.Netscape.com, http://www.xmltree.com, http://www.moreover.com, Http://www.oreillynet.com/meerkat, etc., can also be tools to download to the client installation
Five, the future development of RSS
With more and more sites support RSS, RSS has become the most successful XML application. RSS builds a technology platform that promptly spreads so that everyone has become a potential information provider. I believe soon, we will see a large number of RSS-based professional portals, aggregation sites, and more precise search engines.
