Ding is a project to build an Open Source implementation of Search engine for RSS feeds.

What is RSS, and Why Should You Care ?

RSS fundamentally is a relatively simple specification that uses XML to organize and format web-based content in a standard way. Content owners create an RSS feed, an XML formatted web page which usually consists of titles and brief descriptions of ten or so articles elsewhere on the site. Because feeds are created using the RSS standard, they can easily be read by a software client called an RSS feed reader or aggregator. Most feed readers can handle all of the current standards.

What's different about RSS feeds vs. straightforward web content? Not much, really, but one key difference is crucial: Content published in an RSS feed is typically set up to send out notifications whenever new material is available.

This makes the new content immediately available to feed readers and RSS search engines. Contrast this with ordinary web pages, which are essentially passive and generally aren't accessible to most of us until search engine crawlers find and index them. And then, once indexed, these pages stand relatively little chance of being surfaced by web searchers.

That's why RSS is important, and why its something every serious web searcher should be using. RSS feed readers allow you to subscribe to feeds that you know contain important or useful information, and your feed reader will notify you immediately whenever new content for your subscriptions is available. In short, once you've identified a useful resource that publishes an RSS feed, you can virtually skip searching for it altogether.

RSS has other virtues, as well. Because RSS is popular with both bloggers and news media organizations, you can use RSS search engines to find information in near real-time. For example, with the Indonesian tsunami or the London bombings, RSS search engines allowed users to locate information, images and videos posted by people on the scene hours before traditional media sources had similar eye-witness coverage.

The Ding project has these primary goals:

• Completes with Jabber the conformity Rss search engine.
• Develop a highly robust codebase.
• Be 100% compatible with the reference implementations.
