Introductions

• Name

• Library

• Position

• Does your library use RSS? If so, how?

• Why are you here?

4

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.

5

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.

6

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.

7

Implications of RSS

• Information received in a single location

• Information received in quickly

• Reduced need to visit the originating Web site

8

Are there differentversions 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.

What does RSS look like?

10

How can I find feeds?• Feedster

• Bloglines

• BlogrollsA list of blogs/feeds read by another blogger

• Look for the orange icon…

11

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 right-clicking and selecting “subscribe”.

12

More RSS icons

• “Support the Common Feed Icon” by Rogers Cadenheadhttp://www.cadenhead.org/workbench/news/2872/support-common-feed-icon

13

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/

14

Podcasts• Uses RSS to syndicate audio content

• RSS 2.0 <enclosure>– Like adding an attachment to an e-mail

• Audio Formats– MP3 (Open Source)– AAC (Apple Proprietary)

• iPod not necessary

What is an Aggregator?

• An aggregator is a type of software that retrieves syndicated Web content that is supplied in the form of a web feed (RSS, Atom and other XML formats), and that are published by weblogs, podcasts, vlogs, and mainstream mass media websites.-Wikipedia

• It’s what you need to retrieve and read RSS feeds.

19

What are the differenttypes of aggregators?

• Standalone Clients– FeedReader, Radio UserLand

• PIM add-ins– Pluck, NewsGator, intraVnews

• Browser add-ins– Firefox, Sage

• Web-based– Bloglines, NewsIsFree

• A list is available @http://www.lights.com/weblogs/rss.html

Why do I need an aggregator?

• Most importantly it makes the content of the feed readable

• Checks for updates automatically

• Notifies you of new information

• Displays only new items for you

• May allow you to sort and save information

25

Creating Feeds


22 October 2006

38

How do I create a feed?• Hand-rolled

You type the markup and the content

• Semi-automatedYou type the content, software generates the markup.

• Fully-automatedYou put the content in your blog and software generates a feed based on that content.

• Limitations– Local installation limits mobility and posters

to a single computer.– No built-in FTP. Must transfer the .xml file to

the server manually.– Still in beta (but what isn’t these days?)

RSSxl• Limitations

– Solid knowledge of HTML required to get parsing correct.

– Works better on pages with simpler layouts.– The validation code “will change each month and

you will need to visit this page for the new code.” (Though I’ve found feeds continue to work without updating the code.)

– “If you are using this tool to publish an RSS feed from your website, then you must include a visible HTML link to www.wotzwot.com on your site next to the link to your feed like the following: ‘Powered by RSSxl’”
