This document specifies the "feed" URI (Uniform Resource Identifier) scheme for identifying data feeds used for syndicating news or other content from an information source such as a weblog or news website. In practice, such data feeds will most likely be XML documents containing a series of news items representing updated information from a particular news source.

The "feed" URI scheme is used to identify network retrievable resources that contain information syndicated from one or more news sources. As of this writing the most popular way to represent a syndication feed is through the use of an XML based file format such as [RSS0.91], [RSS1.0] or [RSS2.0]. The "feed" URI scheme is not limited to identifying the aforementioned XML-based file formats but can and should be used to identify other network retrievable resources used to syndicate information from a particular news source.
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119].
The feed URI syntax is primarily dependent on the scheme used to retrieve the data feed over the network. In general, a "feed" URI is written as follows
| feedURI | = 'feed:' absoluteURI | 'feed://' hier_part |
|---|
the syntax for the 'absoluteURI' and 'hier_part' are defined in section 3 of [RFC2396]. A "feed" URI is basically the string 'feed:' or 'feed://' followed by a URI which when accessed over the network returns a representation of the data feed. If the "feed" URI string begins with the string 'feed://' then it MUST be followed by an authority with optional path and query string with the scheme for the URI for accessing the data feed being inferred as the "http" scheme. If the "feed" URI string begins with the string 'feed:' then it must be followed by an absolute URI which is the network accessible location of the data feed.
The "feed" URI scheme has no relative URI forms.
The following are examples of the "feed" URI scheme
| feed:http://example.com/rss.xml | - Identifies the RSS feed at 'http://example.com/rss.xml' |
| feed:https://example.com/rss.xml | - Identifies the RSS feed at 'https://example.com/rss.xml' |
| feed://example.com/rss.xml | - Identifies the RSS feed at 'http://example.com/rss.xml' |
The primary purpose of "feed" URIs is to provide a straightforward way for end users to subscribe to the data feed for a particular online resource while browsing the World Wide Web. The expectation is that clicking on a hyperlink that points at a "feed" URI will cause the Web browser to invoke the specified handler for the "feed" URI scheme which SHOULD provide the user with information about the data feed as well as the possess the ability to subscribe to the feed.
