And the user's daily life, part of the work.
RSS technology is an outstanding representative of the latest technology on the Internet, and is a wonderful flower of news publishing, information release, and interactive communication.
This article aims to introduce the growth history of RSS technology, the status quo at home and abroad, and the future development forecast. In addition, in the second half of the article, we introduced to see the world, the largest Chinese RSS technology and service providers, its service architecture, and RSS electronic publishing solutions for press publishing industry.
Introduction to RSS Technology
Development history of RSS technology
The RSS is "Rich Site Summary" or "Really Simple Syndication" English first letter abbreviation, and Chinese is called "simple information aggregation". RSS is a content package and delivery agreement based on XML standards and widely adopted on the Internet.
RSS technology was born in 1999 Netscape. At that time, Netscape defined a set of languages that describe news channels, RSS, used to deliver site content into the Netscape Navigator internet browser. However, due to the company's internal business decision, the Internet content is lacking, and the net view ultimately releases a 0.9 version of the specification. Microsoft also launched a similar data specification, which is very close to RSS, and trying to use news channel architecture to turn "push" technology into an application mainstream, bundle with Netscape Navigator with Netscape Navigator in the IE browser. However, it is, because the Internet access is slow, the content is lacking, the user is not familiar, this "push" technology has not received a wide range of support from the beginning.
But over time, RSS technology has gradually accepted by people with the rapid growth of XML technology and the rapid growth of blog groups. The application range has also jumped out of the simple blog circle, which is a news media, e-commerce, and corporate knowledge management. An indispensable new technologies such as many areas. In 2001, the development of RSS technical standards was taken over by Dave Winer's company Userland, continued to develop new versions to adapt to new network applications. Through Dave Wena's efforts, RSS upgrade to version 0.91, then reached 0.92, and then received and supported by many professional news sites. During a wide range of applications, many professionals recognize that they need to organize and develop RSS a generic specification and further standardize. A joint group redefined RSS based on W3C's new generation of Semantic Network Technology RSS, released RSS version 1.0, and defined RSS as "RDF Site
Summary. This work does not communicate effectively with Dave Wenna, and Daifei adheres to further developing RSS's subsequent versions 2.0 in the direction of their own ideas, and does not recognize the effectiveness of RSS 1.0.RSS This starts to differentiate to form RSS 0.9x / 2.0 and RSS 1.0 two camps.
Dave Wennai upgraded RSS to version 2.0 in September 2002, and was maintained by the Harvard University Law School Berkman Internet and Sociological Center. The RSS 1.0 version remains maintained by the W3C joint group.
Recently, the famous Internet Search Engine company Google acquired a US large blog service website www.blogger.com, making this website have always used a technology-derived atom that has become the RSS field standard between RSS field. Powerful competitors. Currently, these three technical standard camps (RSS 0.9x / 2.0, RSS 1.0, Atom 0.3) are launching a compatible dialogue, which believes that there will be positive results in the near future.
Although the technical standards have differences, the current RSS content reading software, including the only professional Chinese RSS reader - see the world - all these three technical standards. That is, regardless of the RSS content provider decided to pack its own content, users who look at the world reader software are transparent and have no effect.
RSS technology characteristics
RSS defines the packaging and publishing format of the XML standard to enable content providers and recipients to benefit from it. For content providers, RSS technology provides real-time, efficient, safe, low-cost information distribution channels; for content recipients, RSS technology provides a new reading experience. The significant significant characteristics of RSS technologies are as follows:
l Source diverse personalized "polymerization" characteristics
Because RSS is a widely used content package definition format, any content source can be published in this way, including professional news sites, e-commerce sites, corporate sites, and even personal sites. In the user, the role of the RSS reader software is to "aggregate" to the content of the software to "aggregate" to the interface of the software according to the user's preferences, and provide users with "one-stop" for users. service.
l The timeliness, low cost characteristics released by the information
RSS technology adheres to the concept of "push" information, when new content is "push" to the client reader in the server database, greatly improves the timeliness and value of information. In addition, the RSS packaging of server-side content is extremely simple in technology implementation, and is a one-time job, making long-term information publishing marginal costs almost reduced to zero, which is completely traditional email, satellite transmission, Internet browsing and other release methods. incomparable.
l None "garbage" information, convenient local content management features
The RSS user reader software is characterized by the user to subscribe to the source of content according to the "channel", such as "Xinhuanet International News", "China Auto Network Market", "Tianji Network IT Product Information "Wait. The RSS reader software completely blocks the content of all other users without subscriptions and popping out of advertising, spam, etc. In addition, users downloaded to the reader software locally, users can perform multiple management operations such as offline reading, archive retention, search sorting, related classification, etc., so that the reader software is not only a "reading" device, but also a user Portable "Database".

Typical case analysis
In a commercial website that supports and uses RSS technology, the most representative is the Wall Street Journal Electronic Edition, New York Times electronic version, and Disney's internal knowledge management platform.
Wall Street Journal Electronic Edition << Wall Street Journal >> is the most authoritative financial industry publishing media in Dow Jones. Site electronic version (
Www.wsj.com) sells content services to the public with a price of $ 79. Before the station supports RSS, the user gets the content of the content is: 1) directly access the station site; 2) Email news tips.
Recognizing the shortcomings of the above two content release methods, Wall Street Journal Electronic Edition launched RSS services in early 2004, a total of US News, European News, Asia News, Technology News, Business News, Stock Market Fax, Expert Comments, Personal Technology These channels. For details, please see its official website:

The launch of RSS services has brought the following gains (reference project manager Mike Jones):
l RSS technology real-time makes the subscriber more and easily obtain the first-hand news information information, thereby improving the service quality and customer satisfaction of Wall Street Journal Electronic Edition;
l Provide free RSS news headlines to the public, let more people understand the wonderful and high quality of Wall Street Journalism, help to improve the number of subscribers and promote Wall Street Journal Electronic Edition brands and markets.

l Make more potential users to understand the quality and value of the New York Times, which promotes the growth of the subscription.
Disney Knowledge Management Platform
RSS technology has unique advantages in the field of foreign news information, but also has broad application space in internal knowledge management and information sharing. Disney is the best example.
Disney is the world's most prestigious entertainment product, information provider. Whether it is a movie, cartoon product production, or sports, entertainment information, the collaboration of people with different expertise. Therefore, smoothing and efficient knowledge management and information sharing are the heads of Disney's heads.
Despite the common almost all knowledge management software in the market, Disney is still unable to achieve multi-to-many, personalized, real-time, information sharing targets that support local content management. So they restricted the RSS technology and the symbiotic blog technology to build a new generation of information sharing platforms. The specific practice is that the experts and managers who participate in the project have their own blog sites (of course, relying on the Internet of Disney), protected by their corporate firewalls), everyone puts new ideas, new content, news, plans, discussions, etc. The content is written in your own blog site and released outside the RSS, while other members use the RSS reader to subscribe to these RSS releases, get the latest information, and use the reply to the RSS reader to achieve the purpose of communicating with the member, sharing .
Mike Pusateri, the President of the DISN's New Technology Research, is such a comment on a new generation of knowledge management, information sharing platforms for RSS and blog technology:
l The platform makes the interaction of information very timely, greatly improves the work efficiency and enthusiasm of participants;
l This platform makes each participant more convenient, more effectively manages the content of its reception and release; l Encourage many more exchanges and promotes everyone to discuss in-depth discussion on a topic.
Development status of RSS technology in China
Present Situation Overview
In China, the popularity of RSS technology and the development of the market are in the enlightenment period. It is understood that the world is not fully estimate. At present, the number of domestic RSS users is about 200,000 (which looks at the world RSS reader occupies considerable market share, and the rest is mainly mainly foreign RSS readers in the world). In addition, the number of domestic RSS content providers is still not a lot, and there is currently approximately 500 websites from the Chinese RSS address directory of the world to provide RSS content.
However, the trend of China's RSS market development is very exciting. Recently, a number of famous influential websites have launched RSS content services, which has played a good role in the development of the RSS market, they include:
l Sina

Future lookout
Volkswagen Internet
The popularity of RSS technology in the Chinese public Internet has its foundation and inevitability. First, a large number of new websites and content sources and the diversification of users get information taste makes RSS as the best means of personalized polymerization to pay more and more users' attention and love. Second, more and more content providers have launched RSS services for promoting their own brands, and has launched RSS services to bring greater traffic and popularity to their content. Further, the current business portal is in the considering of their business interests, and the environment obtained by the user information is increasing, popping up, spam, unhealthy content, etc., and the truly valuable information is not looking for. These have forced users to call a new Internet reading experience, a new "portal" experience they can control, thus laid a good foundation for the popularity of RSS.
Pressbook
In the field of news publishing, RSS technology as a new channel for electronic publishing (like Wall Street Journal Electronic Edition) has been useful in the Xinhua News Agency, and gradually matured to commercialization. I believe that in the near future, RSS technology will become a mainstream mature technology in the Press Press.
Enterprise knowledge management
It is currently in the bud period, and the classic case like Disney is still not present. However, with the transformation of the concept of the concept of blogging and the more deeper understanding of its technology, this new technology will believe that the wave of business knowledge management and information sharing services will come quickly.
