The internationalized resource identifier (IRI) was defined by the Internet Engineering Task Force (IETF) in 2005 as a new internet standard to extend upon the existing uniform resource identifier (URI) scheme. The new standard was published in RFC 3987.
IRI extends the URI standard to support I18N in the following ways:
- Support for bidirectional text
- Support for non-ASCII characters
- Support for UTF-8 encoding
