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.
