From Information about Isaak, Brock University's Sakai-Based LMS

The News Tool allows a Sakai courses to display an RSS feed. RSS is a data format that allows users to view continuously updated content from another site. In addition to news, some websites use the RSS format for information that is updated often, such as blogs, events listings, or the revision history of a book. Instructors can customize their News feature by putting in a web address for any RSS feed.
