What is Podcasting? Edit

Podcasting is the merging of two technologies: Downloadable media (audio, usually) and RSS.

Downloadable media is simply a file (such as MP3) stored on a server that users can download and listen to. RSS is a technology that allows a user to subscribe to a podcast and have episodes automatically downloaded to their computer.

RSS Edit

RSS (an acronym used to define the standards Really Simple Syndication or Rich Site Summary) is a way of getting content on the Web. Instead of navigating to a web site to repeatedly check for updated content, RSS automatically brings the updated content for you.

RSS requires you to have a kind of software called a News Reader or Aggregator. Many web sites provide links to files called RSS Feeds that contain information about updated content. For example, supplies an RSSFeed that contains continuously updated headlines. Using a News Reader, you can subscribe to the Headlines RSS Feed, and whenever the feed is updated, you can read the new headlines in your news reader.

Some News Readers are software based, meaning you install them on your computer and they function as a program separate from your web browser. Other News Readers are browser based, basically web sites that allow you to subscribe to the RSS feeds of other web sites and view their content inside the browser.

A podcast is what you get when you upload a media files, such as an MP3, to a web site and provide an RSS Feed for it.

RSS Enclosure Tags are hyperlinks to media files used to attach media to RSS feeds.

Many elements of the podcast environment are generated and managed with Outliner applications. Program subscription lists, podcast directories, show notes, and more are all easily managed and distributed using OPML files.
