- 2. ~Introduction~ 1, Introduction You have the problem happened in Information society. There's too much information. The trouble with living in the Information Age is paradoxical. How are you supposed to keep track of all the news, sports, weather and blogs you follow? How are you going to do that and ?nd time for work, school and family? 2, What is RSS? = RSS is shorted for Really Simple Syndication (at least now more on that later). This service is a way to subscribe to a source of information, such as a Web site, and get brief updates delivered to you. This way to keep track of that it all has grown very popular since its introduction in 1997. 12Äê12ÔÂ16ÈÕÈÕê×ÈÕ
- 3. ~How to use this System?~ 1, About These sources : These sources are called feeds. When you subscribe, you'll get a feed of all the articles published on that particular Web page. In addition, these are often a series of headlines and brief summaries. This lets you scan the articles on the page more ef?ciently. Sometimes you'll even spot more headlines that you might never have seen buried on the original page. 2, How to be displayed? Some Web browsing software automatically detects RSS feeds. Firefox and Opera display the now-common square orange badge for a Web feed in the browser's address bar when they ?nd RSS feeds on a site. You'll see a similar symbol in Internet Explorer's toolbar. Safari shows a blue rectangle with "RSS" written in white letters. 3, How to use? Those emblems show the presence of active RSS feeds on a site to help you get started. Click on one, though, and you'll get a list of options which may seem a little intimidating if you don't know what they mean. Some sites have multiple feeds for the same page with different versions of RSS or a competing standard, Atom. 12Äê12ÔÂ16ÈÕÈÕê×ÈÕ
- 4. ~What is RSS Reader?~ 1, Bene?t Reading RSS feeds can be a great time-saver. In the time it takes you to scan whole Web pages for information, you can review headlines from dozens of sites all collected in one place. On the other hand, the ease with which you can view RSS headlines may convince you that you can subscribe to even more sites. You may end up spending just as much time reading feeds as you used to on regular Web sites. 2, How to use Reading feeds requires a few simple things, many of which you already have. You'll need a computer or compatible electronic device and an Internet connection. After that, you need something that can read, or aggregate, RSS ?les. 3, If you use browser There are disadvantages to using your browser, probably the most serious of which is that if you use more than one computer to access the Internet, you have no good way to synchronize your RSS feeds. 12Äê12ÔÂ16ÈÕÈÕê×ÈÕ
- 5. ~Creating RSS Feeds~ 1, Usable language RSS isn't really that different from a normal Web site. RSS uses the World Wide Web Consortium's Resource Description Framework (RDF) as a guide to tell a feed aggregator how to read the ?le. RDF is based on extensible markup language (XML), a cousin of hypertext markup language (HTML), which is the language used for everyday Web sites. 2, RSS tags RSS tags tell your aggregator how to display the feed on your screen. In addition to the size of the font and other details, RSS tags also include the name of the creator of the feed, the date it was published, when the feed was updated and more useful information that helps you decide which articles to select from the feed and read in full. 3, How to write Unlike writing computer-programming code, most writing in a markup language like RDF involves putting tags around existing copy. For example, to make text bold in HTML, you would just enclose your sentence in a pair of tags. 12Äê12ÔÂ16ÈÕÈÕê×ÈÕ
- 6. ~Trivia of RSS~ 1, The name has been changed The original version of RSS, created by UserLand in 1997, stands for RDF Site Summary or Rich Site Summary. Netscape Communications used the technology to deliver content to users of its MyNetscape portal. In 2003, the name changed to Really Simple Syndication with the release of the RSS 2.0 standard when a new team began work on it. 2, Collect from more media The content you can get via RSS feeds isn't just text. Depending on the kind of feed it is, you might get images, audio and video. When you subscribe to a podcast in iTunes, you're subscribing to a feed, to say that you're just doing it in a different environment. And some Web-based e-mail readers will let you subscribe to a feed to get your mail. 3, If you want to add an RSS feed to Blog Many common blogging tools such as Blogger, Movable Type and WordPress have the ability to syndicate your weblog in RSS, without your having to learn how to write code. These weblog programs include everything needed to publish a feed. The address, title, meta and other necessary information are all included for you. 12Äê12ÔÂ16ÈÕÈÕê×ÈÕ
