FOOD FOR THOUGHT MENU Why a Feed? Whats a Feed?

Wheres the Feed? How a Feed? Who a Feed? When a Feed? Why a Feed? Why a Feed? (1) Automated Web surfing. Feeds are often sent immediately after

something new is posted to the site, so users can know about new content instantly. I enjoy receiving feeds and updated sites on a consistent and up-to-date basis. Why a Feed? (2)

I use feeds to help stay current. Others who have more knowledge of the inner workings of RSS can use feeds to deliver content to their constituencies, either via portals or collaborative Weblogs.

Its a push technology that makes it easy to get new content. Why a Feed? (3) In a nutshell, a Webfeed is a way for online

venues to continuously feed you announcements of their latest content, with links to each new content item. To instantly learn whats new on a site, just check its feed. When youre trying to follow developments at dozens or hundreds of sites, your time savings can be enormous.

Why a Feed? (4) News is delivered to your desktop's aggregator or feed reader rather than you having to visit each Web site to get the

news. Now I get that company's breaking news every hour from more than 4,000 news sources all over the world. This capability saves me precious time when I am looking for newsworthy stories

Why a Feed? (5) RSS feeds provide a way to deliver content to the user, rather than the user having to go out and find the content via traditional Web methods, such as search engines and Web directories. Instead of bookmarking various sites and returning to them every day, the user

can set up a feed . Web feeds can significantly reduce the need to individually re-visit sites of interest for changes or additions. Whats a Feed? RSS (1) RSS is an umbrella term for a variety of XML files which enable the sharing of Web site content. It can be

understood as a Web syndication protocol that is primarily used by news Websites and Weblogs. RSS (2) RSS allows a Web developer to publish content on their Website in a

format that a computer program can easily understand and digest. RSS simply repackages the content as a list of data items, such as the date of a news story, a summary of the story and a link to it.

RSS (3) A program known as an RSS aggregator or feed reader can then check RSS-enabled Web pages for the user, and display any updated articles that it finds.

RSS (4) Rich Site Summary Really Simple Syndication RDF Site Summary

RSS (5) There are several flavors of RSS RSS (6) Earliest

RSS versions (.91, .92, .93, .94) and a later RSS version (2.0) were developed by UserLand ( ) RSS

version 1.0 was developed by the RSSDEV Working Group ( rss-dev/). Userland RSS .091 RSS 1.0 RSS 2.0 BASIC RSS STRUCTURE (1)

Atom Atom is a Web standard similar to RSS. It was created to solve the problem of confusion created by having parallel standards for RSS (e.g, Really Simple Syndication and RDF Site Summary) and create a new more flexible Web syndication format and API.

Atom is an alternative XML Web feed format promoted by for its blogging service. JavaScript RSS Generation (1) Content Management Systems

Urchin (Nature Publishing Group) The first purpose of Urchin is to be a Webbased RSS aggregator and filter. A secondary purpose is to facilitate the

creation of new primary RSS feeds - the software distribution contains modules that help simplify the creation of RSS feeds from information stored in scrapable text formats or relational databases. Wheres the Feed? The Little Orange Icon(s) OTHER INDICATIONS RSS

Quote (1) There are several practical ways in which the LIS community can both exploit the content of RSS, and improve their services through the presentation and re-presentation of RSS feeds.

>>> Quote (2) These do not amount to a revolution, but rather represent a step on the path to better information services, and one which takes advantage of

advances in technology. Roddy MacLeod, RSS: Less Hype, More Action, FreePint no. 161 (June 17, 2004): -10 Thank You for
