RSS FEEDS
RSS is a family of web feed formats used to publish frequently updated content such as blog entries, news headlines or podcasts. An RSS document, which is called a "feed," "web feed," or "channel," contains either a summary of content from an associated web site or the full text. RSS makes it possible for people to keep up with their favorite web sites in an automated manner that's easier than checking them manually.RSS content can be read using software called a "feed reader" or an "aggregator." The user subscribes to a feed by entering the feed's link into the reader or by clicking an RSS icon in a browser that initiates the subscription process. The reader checks the user's subscribed feeds regularly for new content, downloading any updates that it finds. The initials "RSS" are used to refer to the following formats:Really Simple Syndication (RSS 2.0), RDF Site Summary (RSS 1.0 and RSS 0.90), Rich Site Summary (RSS 0.91), RSS formats are specified using XML, a generic specification for the creation of data formats.
The primary objective of all RSS modules is to extend the basic XML schema established for more robust syndication of content. This inherently allows for more diverse, yet standardized, transactions without modifying the core RSS specification.
To accomplish this extension, a tightly controlled vocabulary (in the RSS world, "module"; in the XML world, "schema") is declared through an XML namespace to give names to concepts and relationships between those concepts.Some RSS 2.0 modules with established namespaces are Ecommerce RSS 2.0 Module, Media RSS 2.0 Module, OpenSearch RSS 2.0 ModuleThis presentation contains the history of development of RSS feeds, the modules, the different versions with sample algorithm and the relation between Bit Torrent and RSS feeds.
