I tend to think that the whole internet project's success depends on
its consistency, i.e. that it developed with many constraints but
without contradiction with its
seed. This model, however, suffers from an inconsistency that I call
the "bug" (for "being unilaterally global") that seems to root in the
word "loose" in: its thrid paragraph: "The term 'local' is used in a
*loose* sense, here, since it means 'peculiar to the particular
network' rather than 'a network of limited geographic extent.'".
The term *loose* is something that depends on semantic imagination
and that politicians like, but that lawmakers and engineers dislike.
However, this term seems to translate something perfectly clear (and,
therefore, built-in in the French context of the catenet concept). In
the French language, the word "global" has usually gone beyond its
"limited geographic extent" meaning. It stands for what IEN 48 wants
to be prepared for, and is (I understand) sometimes described in
English as "wholity" (as in the whole is larger than the sum of its
parts). It is conceptual rather than geographical: local is then what
is "peculiar to the [local] particulars", i.e. documented by the "locale" file.
This is why I submit that limitations introduced by the English
language to Louis Pouzin's catenet concept conceived in the French
language context have been further consolidated as constraints by the
IETF, in opposition to the IEN 48 catenet model principles.
These principles are documented in the two following sentences:
- "No explicit network hierarchy is assumed in this model",
- "A very important aspect of this model is that no a priori
distinction is made between a host/network interface and a
The Loc/ID welding, that Louis Pouzin has always objected, is not
consistent with: "The host/network interfaces are assumed to be
unique to each network. Thus, no assumptions about common network
interfaces are made." A community at the "local gateway" interface
has been assumed to be so tight as to melt the host and interface
together in a topological unicity.
In here, we are hit by this same difficulty, which has prevented the
second IEN 48 multitechnology (and implied multilinguistics)
motivation from being accomplished, and also led to the "status quo" strategy.
*Lose locality* was supposed to be supported at the local gateway
"host/network interface", i.e. on both "halves" of the host/network
gateway/interface (remember no distinction must be made between the
two). This means, topologically, this has to happen at the missing
OSI presentation layer six and both ways.
- This has been patched one way by the "locale" file;
- we still missed the "netlocale" equivalent to permit the host to
adapt to what is "peculiar to the particular network" and "unique to
each network". This is now provided in part by IDNA2008.
The remaining unsolved IDNA2008 element is its topological location.
The "unusual" (the term it uses, in that it documents an over the end
issue) RFC 5895 has exemplified the solution in line with RFC 1122,
1958, and 3439. I accepted it because it permits us to read the
internet as an "inter-interface" network, what I call the
"interplus", i.e. inter-presentation layer on the user side. You may
remember that my opposition to Vint was that he wanted to retain the
IDNA2008 layer six functionalities only on the network side - may be
in reaction to IDNA2003 which located them in the very applications
(as do today's APPS or the W3C).
However, one could not venture into my proposed intelligent use
inteface (IUI) without the IETF making sure that (1) it was
consistent with the whole set of RFCs [there are several WGs on that]
and (2) how this would be documented since that IUI could interface
the Host (unleashed from/or through the internet) with multiple
technologies documented by their own SDO that the IAB would have to
liaise with. This second point has resulted in Russ Housley's:
1) agreement and help for the creation of the IUCG at IETF mailing list,
to try to make informed users (IUsers) speak and contribute about
their host and beyond the host technical needs. i.e. in the "unusual"
area of RFC 5895.
2) RFC 6852 which certainly prepares a "global" (French meaning)
internet, but the IUCG cannot endorse yet because it does not include
an MS convergence process in case of discordance (concepts,
protocols, parameters, uses) between what they call "global
communities". This is what the NTIA asks ICANN to document.

This is a very important question that also affects the variants. The
"inter-IUI"/Interplus catenet model implies that "no a priori
distinction is made between a host/network interface and a
gateway/network interface". This cascades to the host/human
interface. At the H/H stratum, IDNA2008 appears as a "netlocale",
i.e. how the "center of the information society" (the person) is to
digitally deal with its different internet supported relational
spaces (in our case, through the physical host/human interface: the
Unicoded (or not) keyboard and screen.
We, therefore, have to be careful at locating constraints (every
solution implies constraints) at a place of least nuisance (Harald
cited the "principle of least astonishment"). My own rule was: "no
gateway trespassing MUST".
Therefore, I would aswer: no. You might remember that I was very
opposed to whatever could block the support of French majuscules, as
also an example of orthotypographic support (which can be a very
broad matter). I still wish to experiment their support at the IUI
level in a more generalized digital and semiotic environment before
determining what belongs to end to end (if any) and to fringe to
fringe (what I am, [and others seem to be] now engaging).
Much will depend on the work on the ML-DNS (Multi-Ledger DNS) I had
said at the begining of IDNA2008. But this is another issue that
calls for a series of I_D I might introduce after the Sao Paulo
meeting. The considerations regarding the cost to support of a
language may then totally change. This is line with my ".fra" project.

A lot of energy is spent in different fora to attain some consistency
in the digital multilinguistics area. I have not noted yet, in those
I follow, a real degree of convergence. I am on
