The following normalizations are described in RFC 3986 [1] to result in equivalent URIs: . Converting percent-encoded triplets to uppercase. The hexadecimal digits within a percent-encoding triplet of the URI (e.g., %3a versus %3A) are case-insensitive and therefore should be normalized to use uppercase letters for the digits A-F. [2] Example:
Simultaneously, the IETF published the content of RFC 3986 as the full standard STD 66, reflecting the establishment of the URI generic syntax as an official Internet protocol. In 2001, the World Wide Web Consortium's (W3C) Technical Architecture Group (TAG) published a guide to best practices and canonical URIs for publishing multiple versions ...
URL encoding, officially known as percent-encoding, is a method to encode arbitrary data in a uniform resource identifier (URI) using only the US-ASCII characters legal within a URI. Although it is known as URL encoding , it is also used more generally within the main Uniform Resource Identifier (URI) set, which includes both Uniform Resource ...

In programming, a file uniform resource identifier (URI) scheme is a specific format of URI, used to specifically identify a file on a host computer. While URIs can be used to identify anything, there is specific syntax associated with identifying files.
The MSRP protocol is defined in RFC 4975. [1] MSRP messages can also be transmitted by using intermediaries peers, by using the relay extensions defined in RFC 4976. [2] MSRP is used in the RCS context, especially for the instant messaging, file transfer and photo sharing features.
URI schemes registered with the IANA, both provisional and fully approved, are listed in its registry for Uniform Resource Identifier (URI) Schemes. These include well known ones like: file - File URI scheme; ftp – File Transfer Protocol; http – Hypertext Transfer Protocol; https – Hypertext Transfer Protocol Secure
A Uniform Resource Name (URN) is a Uniform Resource Identifier (URI) that uses the urn scheme. URNs are globally unique persistent identifiers assigned within defined namespaces so they will be available for a long period of time, even after the resource which they identify ceases to exist or becomes unavailable.
