This article lists common URI schemes. A Uniform Resource Identifier helps identify a source without ambiguity. Many URI schemes are registered with the IANA; however, there exist many unofficial URI schemes as well. Mobile deep links are one example of a class of unofficial URI schemes that allow for linking directly to a specific location in a mobile app.
URI schemes registered with the IANA, both provisional and fully approved, are listed in its registry. These include well known ones like:
ftp – File Transfer Protocolhttp – Hypertext Transfer Protocolhttps – Hypertext Transfer Protocol Secureimap – Internet Message Access Protocolirc – Internet Relay Chatnntp – Network News Transfer Protocolas well as many lesser known schemes like:
acap – Application Configuration Access Protocolicap – Internet Content Adaptation Protocolmtqp – Message Tracking Query Protocol (RFC3887)wss – Encrypted WebSocket connections| Scheme | Purpose | Defined by | General format | Notes |
