Hi John, (03)
Your complaint was exactly that "universal" was a larger context that
"international" so seems entirely relevant to me that you misunderstood what
"U" meant, as without that misunderstanding your complaint makes no sense. (04)

IRI was defined by the IETF 9 years ago. Even SPARQL 1.0 from 2008 used IRIs,
so this is very old news. (06)
It's clear that there are members of the set IRI that are not members of the
set URI and so in a standard they should be clearly labeled as different sets -
which the IETF kindly did. (07)
Their motivation was about the Web being friendly to the entire world. Quoting
the RFC:
A Uniform Resource Identifier (URI) is defined in [RFC3986] as a
sequence of characters chosen from a limited subset of the repertoire
of US-ASCII [ASCII] characters. (08)
The characters in URIs are frequently used for representing words of
natural languages. This usage has many advantages: Such URIs are
easier to memorize, easier to interpret, easier to transcribe, easier
to create, and easier to guess. For most languages other than
English, however, the natural script uses characters other than A -
Z. For many people, handling Latin characters is as difficult as
handling the characters of other scripts is for those who use only
the Latin alphabet. Many languages with non-Latin scripts are
transcribed with Latin letters. These transcriptions are now often
used in URIs, but they introduce additional ambiguities. (09)
The infrastructure for the appropriate handling of characters from
local scripts is now widely deployed in local versions of operating
system and application software. Software that can handle a wide
variety of scripts and languages at the same time is increasingly
common. Also, increasing numbers of protocols and formats can carry
a wide range of characters.
This document defines a new protocol element called Internationalized
Resource Identifier (IRI) by extending the syntax of URIs to a much
wider repertoire of characters. It also defines "internationalized"
versions corresponding to other constructs from [RFC3986], such as
URI references. The syntax of IRIs is defined in section 2, and the
relationship between IRIs and URIs in section 3. (010)
The "I" and internationalisation of the Internet and Web is a huge step forward
for folks around the planet, but now that it's done you should be safe from
having to learn anything new on this subject until "U" does come to mean
universal. (011)
Cheers,
David (012)
