The protocol in a nutshell is as follows:

• An feed URL (a “topic”) declares its Hub server(s) in its Atom or RSS XML file, via <link rel=”hub” …>. The hub(s) can be run by the publisher of the feed, or can be a community hub that anybody can use. (Atom and RssFeeds are supported)

• A subscriber (a server that’s interested in a topic), initially fetches the Atom URL as normal. If the Atom file declares its hubs, the subscriber can then avoid lame, repeated polling of the URL and can instead register with the feed’s hub(s) and subscribe to updates.

• The subscriber subscribes to the Topic URL from the Topic URL’s declared Hub(s).

• When the Publisher next updates the Topic URL, the publisher software pings the Hub(s) saying that there’s an update.

• The hub efficiently fetches the published feed and multicasts the new/changed content out to all registered subscribers.

The protocol is decentralized and free. No company is at the center of this controlling it. Anybody can run a hub, or anybody can ping (publish) or subscribe using open hubs.

To bootstrap this, we’ve provided an open source reference implementation of the hub (the hard part of the protocol) that runs on Google App Engine, and is open for anybody to use.

Why accessible? Because…

• Users with color vision deficiency, or color blindness. The plugin does not use color as a primary indicator of a change in state for the slider. Instead, the “back” and “next” navigation is either visible or hidden. There is also an indicator that communicates the total number of news items.
• Users with limited or poor vision, but who do not use a screen reader. If the user chooses to resize the text via the browser file menu, the slider will flex vertically to accommodate the larger text, and still function. This is primarily a function of the CSS, and it is suggested you maintain a variable font size in order to take advantage of this capability.
• Users that are legally blind, and who browse Web pages with a screen reader
• Users that browse with the keyboard and an adaptive device such as a mouth stick
• Users who have turned off JavaScript or CSS
• Users who have turned off images

It works in Windows:  IE 6+, FF 2+, Opera 9+, Safari 3+
