feed: URI scheme
The topic is feed protocol. Wikipedia’s feed protocol:
The feed: URI scheme (sometimes erroneously called “feed protocol“) is a non-standardized URI scheme designed to facilitate subscription to web feeds, specifically the automatic launching of a news aggregator when a hyperlink to a feed is clicked in a web browser.
Instead of feed protocol, we have to use feed: URI scheme and we have seen that it is a non-standardized URI scheme. So what is URI scheme? Here is Wikipedia’s response: URI Scheme
A URI scheme is the top level of the URI naming structure.
URI schemes are sometimes erroneously referred to as “protocols”, or specifically as URI protocols or URL protocols, since most are associated with particular protocols, and often have the same name. The http: scheme, for intance, is used for referencing HTTP resources.
URI schemes should be registered with IANA, although many non-registered schemes are used in practice.
Official IANA-registered schemes examples: http, https, ftp, mailto, etc…
Unofficial but common URI schemes examples: about, aim, feed, etc…
