Application of RSS, as well as some of my thoughts in the same e-mail, I will involve the following elements: 
  • RSS cited examples 
  • RSS entry Advanced 
  • What can we do as well as solutions 
  [Text] 
  1, RSS examples cited in introducing the concept of RSS before I would like to cite some of the more outstanding embedded RSS service site:

  Among them, "RSS feeds news -" I think has done the most serious, it is worth learning.    Recommend. 
  Second, the RSS entry Advanced 
  1. What kind of things are RSS 
  RSS on the site have their own understanding and definition of the language I used here to describe what is RSS: 
  An XML file, at the index page of links are pointing it usually is a marker of "XML" or "RSS" in the small orange icon to open it in the IE web site is not found, but a structure of a tree paragraphs labels text files (like html files), text can be read directly, but many in the folder tab been tumultuous ones read it very convenient. 
  The question is: what use is it?    How? 
  2.RSS use - subscribers; Abstract reading list after learning I realize that RSS recorded in the site recently updated articles, including headlines, summaries and the original site, such as links to the article.    RSS is an XML document itself, as it can be as static HTML file stored on the server.    Users need from the browser (such as IE) to visit the site's home page, the only direct link to the RSS may be able to receive the latest site content.    There are several advantages of doing so, a user can escape the hype, the advertising on the Web directly grab the essence of information, and the other users can develop their own favorite channel classification, rather than a passive acceptance of a Web site for Channel classification. 
  [Deepen our understanding of the initial reading recommendations Skip directly Reading 3.] Here will be faced with a "push" and "pull" concept, if you understand this streaming media technology that will not be unfamiliar.    Figuratively speaking, the traditional Web site like a bookstore, everything inside the library, using a Web browser users who like to buy books, you browse the Web site to obtain information, like you visited bookstores to buy books. 
  There are two possibilities, you do not have First goal: you from the south of a row of shelves comes out to the north side of a row of bookshelves, each book is read together with brief preface, table of contents, chapter I found a word Manual Yes, and then bought.    Another possibility is that you have goals "Spark four-word English Handbook," you accordance with the classification markings on the shelves to find, or they may be called Bookstore services are born to call on him to tell him the title help you to find this book (Web search engine ).    Found, bought. 
  But both belong to "pull" areas, because you need to personally Qunajia bookstore, this process you will receive many useless information, such as you do not know what is a new book shelves, all the way at the past Aged found that many of them are old stuff and garbage, or you do not clearly defined and you have to find what is the title of the book, a warm and efficient but patience is not savvy Health services in a matter of seconds to help you have a lot of books, then you pointed out repeatedly that this is pointed out repeatedly that this is not one that you want.    This is the client from the server and "pull" information helpless. 
  Relative concept is "pushing."    Used bookstore example, in order to allow people to buy books that bookstores to buy books, bookstores offer a new free "subscription" service: regular bookstore to the newly-print book titles good mailing list to the client's home, the list Each book, including the title, briefs, the number of books, the list is very clean, no advertising, and allows you to subscribe to a particular type of book lists, for example, you are only concerned about the newly published streaming media technology, the book on the chicklit no interest in the city, you can only subscribe to the "information and computer technology" book list.    Book list can be considered as from the server "push" to the client a service.    RSS similar book on the list. 
  3.RSS open approach - RSS reader solutions 
  • The most serious of the programme is a specialist RSS reader, a software, and the use of FoxMail manage your e-mail similar.    He was responsible for the management of the many RSS Feed you can customize channel group, and add new channels, in a friendly interface to read.    Many such software, I have used "look at the world news reader," which in similar software is a relatively early; free.    I am currently using FeedDemon1.5, channel management function more excellence, more comprehensive standards support in the RSS users masses won good reputation; sharing version, keygen; In addition, he also comes with a lot of foreign Feed often opportunities of network particularly recommended. 
  Shuimu cattle-on, use Outlook to read RSS, cool feeling, alas, I am not equipped machines. NET environment, he can not run that version of Outlook. 
  • I think that a more acceptable to people that this is the way: the browser function own RSS reader.    In the Web browser to open at the same time people look at an application RSS, it appears that some are too avant-garde.    This winter vacation, I found a compromise approach: use Maxthon web browser, as many people have used the MyIE, based on the IE core, Maxthon In addition there are many features, including an RSS reader and management, interface compact and channel management function impertinent remarks in decent RSS reader software.    If I have to do RSS recent promotion, I will vigorously pushed Maxthon. 
  4. RSS [choose] comparative advantage 
  • Perhaps many people think common on the Web site, "recently updated" Notice.    I think that the RSS and is essentially different from his.    There are three reasons: 
  First, the update bulletin on the Web page limit to a maximum of the title and provide links, no summary, or only 1-2 new article summaries.    Been engaged in planning or graphic design Web people will know "the coordination and clean this contradictory information" is a very big headache thing.    RSS on the Web can be independent, and not advertising, Logo, Banner, classification, and other Web navigation elements contending for spheres of influence, posed as a common XML small orange icon in the first quietly in a corner, waiting for smart people to click . 
  Second, notice the attendant and often include some statement (of these users are often not interested), "recently updated" mixed users concerned about things on the inside that is not enough for the sake of users. 
  Third, users can not develop its own channel classification through management Favorites to achieve self-definition channel some of the idea of classification is not rational, because at the same time opened a dozen cloth Man advertising Web browser process (or thread), Internet bandwidth in the peak period of tension, the client PC memory is not big enough under the current conditions, some barbaric.    An RSS document itself is 5 Kb to 10 Kb the text, using a 200 Kb of Flash ads transmission bandwidth and memory footprint, we can obtain more than 20 sites as key elements: Summary List. 
  • Compared with e-mail subscription. 
  Consider constantly updated, Email subscribers will network storage burden.    And the list of updates expired worthless, there is a waste.    So keep only the latest list, kept in the server, users need when using HTTP protocol transmission.    (This point is made under the RSS denied the use of "push" technology, I think that too pedantic a meaningless final analysis, the Internet is not peer-to-peer network topology, not the client request packet from the data server can not take the initiative to outsourcing clients, So absolutely "push" technology does not exist.) 
  5. RSS [choose] originated with the standards battle this text information extracted from "硅谷动力Network": 
  RSS then what does?    There are two more general argument, one is the "Rich Site Summary" or "RDF Site Summary" and the other one is the "Really Simple Syndication," The reason why there are these differences, we must start with the development history of RSS. 
  The initial version RSS 0.90 is designed by Netscape, is used to establish an integrated all major news portal site content, but the 0.90 version of the RSS norms too complex, but a simplified version RSS 0.91 with the Netscape company also The project was abandoned in 2000 and suspended. 
  Soon, a blog devoted to writing software development company UserLand RSS took over the 0.91 version of the development, and regarded it as their blog writing one of the Basic function of the software continues to develop, and gradually introduced 0.92,0.93 and 0.94 versions.    As the network's popular blog, RSS, as a basic function has also been a growing number of web sites and blog software support. 
  UserLand took over the company and continued development of the RSS at the same time, many professionals who understand the need to adopt a third-party, non-commercial organizations, the RSS development of a common standard, and further standardization.    So in 2001 a joint team in the development of RSS version 0.90 under the principle to a new generation of w3c Semantic Web technology RDF (Resource Description Framework) as the basis for a redefinition of the RSS, issued RSS1.0, and RSS defined as " RDF Site Summary. "    However, this did not work with the company UserLand effective communication, UserLand RSS 1.0 companies do not recognize the validity of, and in accordance with their own vision of the further development of a follow-up version of RSS, in September 2002 issued an updated version of RSS 2.0, UserLand RSS companies will be defined as "Really Simple Syndication." 
  Currently RSS RSS 0.9x/2.0 has been divided into two camps and RSS 1.0, due to differences between the RSS 0.9x/2.0 and the existence of the extensive application of the status quo, RSS 1.0 is not yet a true ISO standard. 
  [End quote] 
  Fortunately, 3. Mentioned in the two solutions of these two standards (1.0/2.0) have very good support. 
  6. Polymerization concept - a collection of RSS Feed is the Element Feed, I understand the meaning of the RSS Feed entities.    Here is a semantic distinction.    RSS usually refers to the technology itself, more often as an abstract concept has been all comes down.    RSS Feed is the XML document itself.    We in the RSS reader to add specific channels at the Feed. 
  Feed will be divided into a number of categories, as a channel group, I understand that the polymerization.    RSS Feeds can be exported after the list of generic extensions called opml (Outline Processor Markup Language).    Can be used to back up or share your RSS resources, similar to the Export-mail address book for you csv files. 
  7.RSS expand the field of application of RSS is now concentrated in the two types of services: News and Blog provide depth exchanges. 
  In addition XMLcn some professional forums such as the Forum, the Forum of each plate provided RSS feeds. 
  This shows that knowledge content, timeliness of information value is relatively high, is not longer than the renewal cycle for days for the website to provide RSS services. 
  In many colleges and universities internal news site, the application of RSS is almost blank.    "University of Electronic Science and Technology Information Centre" to provide RSS, but has not seriously, the first step is trying to fashion technology, are not intended to be provided as a service.    From this point leads me some ideas, in the "three"-1999. 
  Also this afternoon, I used to read RSS news, see this - from a news: 
  First mobile RSS aggregator of information - on the line (and a reporter Anli) Recently, Xi'an Jiaotong University Mastery development of new technologies limited liability companies in the cell phone charm net wap.51tone.com website developed the world's first mobile RSS ( RSS).    With the traditional search engine-information-gathering methods, the RSS technology is in full accordance with the subjective desires of users by users concerned about the topic or keyword expression, the large number of scattered distribution of the required information automatically summarized and "Push" to mobile phones, as long as phone online, we will immediately see classified according to their own wishes of the latest and fastest customized information can be constantly updated content, enabling cell phone users to keep pushing for the latest information sent by RSS. 
  [End quote] 
  This shows that the end-user will also be a mobile RSS application of the audience.    This again reminds me of the other day to see "computer", Morgan described the development of brain-dead PC saturated mobile communications in this century will lead the IT industry in the commentary has been a touch.    RSS has been able to be mobile phone users to visit because it comply with the XML standard, and also to comply with WML phones XML standard, integrated work very easily.    I think this is the original intention of W3C it. 
  Third, we can do what 
  1. STV as a member, I would like to -- 
  • In the video media page Tsinghua students add RSS news links.    Rationale: 
  First: To facilitate students to read STV trends and the recent renewal programmes. 
  If you use RSS Web Access will not be reduced volume?    I do not think that, first of all, RSS is humane, results-oriented modern philosophy, I believe that will be welcomed by the great majority of students, if we take the lead in the campus network launched RSS channels will attract a lot of attention, thereby enhancing the total site visits, followed by RSS Heading the list is a summary also links to read the full text of Web pages, especially our video-on-demand can only be opened from the Web click on the link flow.    Therefore RSS will not reduce the volume of Web access, but on the rise. 
  Second: creating a campus network clean, efficient environment. 
  Information Redundancy small, high signal to noise ratio, in line with the RSS concept of the campus humanistic spirit. 
  We STV providing relatively avant-garde of the first RSS service, network television is students full of vigor and vitality, and with certain technical strength for the overwhelming majority of students really a symbol of service and decals. 
  2. At present I can think of the technology solutions lazy approach is to find Tsinghua students maintain portal development team, asking them to amend the entire site source, the new RSS channel links.    It need hardly what workload code is very simple. 
  If we are to have sufficient authority STV, through the management of the panel "edit page" option (ie OUYANG Jun Tao and Hao Liang warned us not to go to that point), may be able to complete its own server-side RSS service, I dared tried, I would like to request this, allow me to try, I will be very careful very cautious. 
  If there is no such a large pages management authority, I can give the idea of code (winter vacation time I have been in the ASP environment code had two ideas). 
  The first one: each add, edit a new article, the database must be updated, the database is updated subroutine (or function), add a new code, the article reads as several articles in the table, with a very straight SQL statement White: "SELECT TOP 15 * FROM table article ORDER BY modified field DESC."    Directly on the server, then the output text flow (FSO), in line with production standards RSS (1.0/2.0) XML documents.    Web links at this static rss.xml documents. 
  The second: do not change the source, add new asp file, for example, called rss.asp, read from the database as several articles directly to spread gave http client, the server not generate static xml document. 
  Comparing the two, 
  The first one to a few Kb of server space, but users request static pages xml, handling up faster than asp.    For example, "One," in: China Daily, China blog. 
  The second to increase server computing more affordable, but to avoid redundancy document server drives.    For example, "one": electronic technology, Baidu.    I preferred the first. 

  3. CONCLUSION 

  RSS now in full swing, the growing user base.    We have no reason not to believe that in the next few years, the RSS will spread, as well as the people and the same Web, including women and children. 

  Now that we have this new understanding of the RSS things, and found that it is a good thing, and try, it did not achieve what cost. 

  I hope that the high-level STV to consider - Tsinghua students in the new media RSS channel video subscription services - this matter.
