NameLibraryPositionDoes your library use RSS? If so, how?Why are you here?

What is RSS?

5

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 items on the Internet.

The History of RSS

6

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.

How does RSS work?

Information Provider

Information Receiver

How does RSS work?

8

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.

Are there differentversions of RSS?

9

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.

Implications of RSSInformation is received in a single locationInformation is received quicklyThe need to visit the originating Web site is

reducedand…

Reading Feeds

What is an Aggregator?

19

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.

What are the differenttypes of aggregators?

PIM add-insPluck, NewsGator, intraVnews

Browser add-insFirefox, Sage

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

Why do I need an aggregator?

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

“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’”
