Technical publications, especially standards produced by the IETF and by the W3C, normally reflect a view outlined in a W3C Recommendation of 30 July 2001, which acknowledges the precedence of the term URI rather than endorsing any formal subdivision into URL and URN. URL is a useful but informal concept: a URL is a type of URI that identifies ...
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. [ 1 ]
A uniform resource locator (URL), colloquially known as an address on the Web, [1] is a reference to a resource that specifies its location on a computer network and a mechanism for retrieving it. A URL is a specific type of Uniform Resource Identifier (URI), [2] [3] although many people use the two terms interchangeably.
ASCII code points that are invalid URI characters may be encoded the same way, depending on implementation. [ 6 ] This conversion is easily reversible; by definition, converting an IRI to an URI and back again will yield an IRI that is semantically equivalent to the original IRI, even though it may differ in exact representation.
NAPTR records map between sets of URNs, URLs and plain domain names and suggest to clients the protocols available for communication with the mapped resource. [3] Each NAPTR record contains a service name, a set of flags, a regular expression rule, an order value, a preference and a replacement pattern.
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.

Indeed, the Internet employs several universally applicable naming methods: uniform resource name (URN), uniform resource locator (URL), and uniform resource identifier (URI). Naming systems have several other characteristics. The entities that assign and manage names can be distributed, centralized, or hierarchical. Names can be human-readable ...
