3. Publishing a podcast

Before users can listen to your podcast it requires some means of publication. The most common way to publish a podcast is by using an RSS feed, which is a special file that points to the podcast (the MP3, MPEG4 etc.) and contains your description of the podcast's content.

To publish a podcast the author needs the following:

  1. Web space to store the podcast (MP3s etc.) online.
  2. An RSS generator, such as Oxford University's OXITEMS newsfeed to point to the content.
  3. A medium to view the podcast (commonly iTunes but also other digital media players and modern web browsers, such as Firefox).

Promoting a podcast

To avoid podcasting in a void, podcasts are promoted (advertised, and listed in searches) using Really Simple Syndication (RSS) for news feeds. Each feed is a simple XML file containing textual information about e.g. podcasts it links to. The information about each item not only includes the title, author and description of each individual podcast, but also whether it belongs in a series, and what number in the series it is. Software like iTunes picks up the RSS information and displays it to the user so they can view, subscribe and download the podcast in the easiest way possible. Software that can pick up and view RSS feeds are known as aggregators.

For more information about publishing and promoting podcasts, see the Steeple Podcasting Booklet, for example the sections on Publishing, Encoding mp3 with iTunes , and RSSformats.

3.1. OXITEMS RSS System

OXITEMS is an RSS newsfeed system developed here at Oxford by OUCS. It allows users to add and maintain news items (announcements, news, events, podcasts etc.). These feeds can be subscribed to by digital media players allowing the end user to receive news updates, podcasts ect. without the need to visit the originating web site themselves.

The first step the author has to make is to upload the podcast to their web space, e.g. a college server, their users web space or to a course area on the WebLearn VLE. You cannot upload files to OXITEMS as it is not a filestore, nor are other RSS feeds; they merely link a news item in a newsfeed to an assocated file (called a enclosure) and contain textual information about this linked file. Once the location of the podcast is known, follow the instructions below:

Adding your podcast to OXITEMS

  1. Go to the OXITEMS web site. Accessing the OXITEMS system requires authentication as a member of Oxford University through WebAuth.

3.2. Accessing your podcast feed

In order to check whether your podcast feed and files work on the web you need to subscribe to the feed and download the file(s) in question. These instructions relate to using iTunes to check the feed. If you do not have iTunes already, visit http://www.apple.com/itunes/ to download the program. Install this onto your computer. If you do not want to install iTunes onto your system, you can also check the url of the feed using modern web browsers such as Firefox and Opera. For instructions on using Firefox to add a Live Bookmark to the feed see: Subscribing to RSS Feeds. Alternatively there are other digital media players available that you can use instead. See the Links section for a selection of other players.

  1. Open iTunes and click on [Advanced] found on the top most menu.
    Advanced button

  6. Click the Get button next to your new item. iTunes will access and download the file to your machine.
