feed URI scheme

The feed URI scheme was a suggested uniform resource identifier (URI) scheme designed to facilitate subscription to web feeds; specifically, it was intended that a news aggregator be launched whenever a hyperlink to a feed URI was clicked in a web browser.

The scheme was intended to flag a document in a syndication format such as Atom or RSS.

In 2006 the feed URI scheme was supported by several popular desktop aggregators, including NetNewsWire, FeedDemon, Safari, and Flock.

As of 2011[update] no effort seems to be underway to officially register the scheme at IANA.

Here is in essence the userinfo@host:port part of the original http URI, and is the following absolute path introduced by a slash "/"; it can be empty or absent.
