Introductions • • • Name Library Position Does your library use RSS? If so, how? Why are you here? 3
What is RSS? • Depending on who you ask it stands for either “Really Simple Syndication”, “Rich Site Summary”, or “RDF Site Summary”. • “Really Simple Syndication” is the de facto definition today. • RSS is an XML language for syndicating news items on the Internet. 4
The History of RSS • RSS 1. 1 (update to RSS 1. 0), RSS 3. 0 (a new, independent project), and “Simple Sharing Extensions” (an update to RSS 2. 0 by Microsoft) have all been proposed but have had no impact yet. 5
How does RSS work? • The information provider creates an RSS file. • Users subscribe to the file via an aggregator. • When the author updates the RSS file, the user is automatically notified of the new items and may read them on their schedule. 6
Implications of RSS • Information received in a single location • Information received in quickly • Reduced need to visit the originating Web site 7
Are there different versions of RSS? • Yes. In fact, there are currently eight different versions: RSS 0. 90, 0. 91, 0. 92, 0. 93, 0. 94, 1. 0, 2. 0, & Atom Feeds • Each has different features from the author’s point of view. • Today’s aggregators support all of the versions transparently. • RSS 2. 0 & Atom are the most common. 8
What does RSS look like? <? xml version="1. 0" encoding="UTF-8" ? > <rss version="2. 0"> <channel> <title>BCR: The Third Indicator</title> <link>http: //www. bcr. org/publications/thirdind /</link> <description>The Third Indicator, published monthly, is a technical memo focusing on OCLC products and services.

How can I find feeds? • Feedster • Bloglines • Blogrolls A list of blogs/feeds read by another blogger • Look for the orange icon… 10
How do I subscribe to a feed? • Look for an orange icon: • Depending on your aggregator, the subscription procedure may range from copying and pasting the link to rightclicking and selecting “subscribe”. 11
More RSS icons • “Support the Common Feed Icon” by Rogers Cadenhead http: //www. cadenhead. org/workbench/news/2872/supportcommon-feed-icon 12
A standard icon? • The move is to establish this icon, originally proposed by the Firefox, folks as the syndication icon. • Microsoft’s Internet Explorer 7 will use this icon. • http: //www. feedicons. com/ 13
Podcasts • Uses RSS to syndicate audio content • RSS 2. 0 <enclosure> – Like adding an attachment to an e-mail • Audio Formats – MP 3 (Open Source) – AAC (Apple Proprietary) • i. Pod not necessary 14
