•RSS is a technical specification for syndicating information (i.e., distributing it to multiple Web sites for online publication).•The available RSS output from a Web site is called a feed . Feedburner and Atom are popular feed format.

Technology is simple• XML…..OPML
• Markup Languages• A markup language is a set of codes that
determine how Web content looks or how it is structured.
• Examples• HTML ; XML (extensible markup language)
• XML viewer = RSS aggregator
• Aggregators are also called news readers.
• Examples: Bloglines, Google Reader, Netvibes

SCOOP IT
Some observations• Be specific
• Internet is used for INFORMATION and for COMMUNICATION. RSS feeds serve the communication function. That means, opinions, bias, …these are valuable too.
–Esp news- V V Selective.
Some Perspective• Internet has its limitations• Search Engines have their limitations• Individual users have their limitations• Not all websites have RSS Feeds• RSS Readers have their limitations• Esp. Premium content….which represents
knowledge based on research & deep thinking are still inaccessible via free resources.
• V V V selective….so shd not be dependent entirely on RSS Feeds.
»Other tools required….one such tool is Delicious.
