NamingSystem: Internationalized Resource Identifier (IRI)

Official URL: http://terminology.hl7.org/NamingSystem/iri				Version: 1.0.0
Active as of 2023-03-16			Computable Name: IRI

As defined by RFC 3987 (http://www.ietf.org/rfc/rfc3987.txt). Internationalized Resource Identifiers (IRIs) are the internationalized version of URIs (which are also defined as a NamingSystem as https://terminology.hl7.org/4.0.0/NamingSystem-uri.html) that allow Unicode characters to be used in the identifier with some restrictions, which was defined by the Internet Engineering Task Force (IETF) in 2005. An IRI such as 'https://hi.wikipedia.org/wiki/हृदय' can be percent-encoded into the URI 'https://hi.wikipedia.org/wiki/%E0%A4%B9%E0%A5%83%E0%A4%A6%E0%A4%AF' to be used as a URL, but the IRI is easier to read, particularly for readers of non-Latin languages, and is natively supported by many tools, including many browsers, HTTP libraries, and in the Resource Description Framework (RDF). IRI values MUST NOT be used in Identifier.system or Coding.system. They MUST only be used in Identifier.value (where Identifier.system = urn:ietf:rfc:3987).
