Any implementations that depend on country/language codes never changing are by definition broken implementations, since there was never any guarantee that codes would never change. Change happens, and IT knows how to cope; it's a versioning problem, and that's not a particularly difficult problem. Now I fully agree that in hindsight the ISO and its appointed MAs could have provided a better record of changes. > If for whatever reason ISO and the UN decided that "US" should > be used to designate the country of France, I doubt you'd expect every > software vendor to update all of their deployed installations to use > "fr-US" instead of "fr-FR", and for every user to go through every data > repository they manage to make such changes in their data. The only way that would be likely to happen would be if there were no longer a "US" *and* if the ISO and UN representatives of France were to initiate a request for such a change. One would presume that they would have good reason to do so, and could explain said reasons in order to convince their ISO and UN counterparts to agree to the change. Under those hypothetical circumstances, I can only assume that software vendors who care about such matters would either agree with the hypothetical reasons or would have acted to convince those in favor of the change of reasons to avoid the change. And while I would not expect users to retroactively change documents any more than I would expect coins and paper money to be reissued with old dates but new designations of country name, I would expect that as of the agreed-upon effective date of the change that new documents would be prepared in accordance with the new standard. It's difficult to be more precise about such a wild hypothetical, but consider similar changes made to time zones... > The people that maintain time zone definitions may have their means for > changing times; that's fine for them.

Sure they are; it's another instance of the same sort of versioning problem, with the same root causes, viz. items which are changed (more frequently than some would like) by politicians. > The group here that has focused > specifically on language-tagging issues for several years has evaluated > issues that affect language tags and the impact of changes and has > decided what is best practice for *this* domain, and it is to maintain > stability of data rather than cater to whims of political > administrations. Now that the horses have all run away, you'd better make sure the stable doors are locked. :-) There was never any guarantee of stability of country codes or of language codes. Declaring at some time in the future that today's meaning of sr-CS never meant what it in fact does mean doesn't create stability; it creates instability -- it doesn't make the versioning problem go away; it adds yet a third version to the existing two. > > "Designed" or not, country codes *are* read by humans; they > > appear in top-level domain names.

URIs aren't guaranteed to be persistent; the Foo company buys the Bar company and after a while bar.com URIs stop working because they've been changed to foo.com URIs.

Feh. Whatever. The human-readable stuff that corresponds to the code which you say shouldn't be read. The stuff without which codes are meaningless. The stuff without which two communicating parties cannot agree on the meaning of "XX". > > > this is no different for RFC 3066bis. > > > > It is very different; under the proposed draft, there is only > > an English definition, somebody wishing to provide a French > > definition finds that he has none and must resort to an > > unofficial translation. > > The more you press this, the more silly it seems. RFC 3066 does not > anywhere discuss display names If I have used the term "display" in conjunction with the language/country names it is only incidental. Effective communication, including language tagging, is an end-to-end process (RFC 1958). Without agreement on what a code *means* there is no effective communication. And the ISO lists provide the definitions that attach meaning to otherwise meaningless combinations of letters. The stuff that the humans at each end of the communications channel use to identify the language. > The source ISO standards are every bit as accessible as they ever > were, and just as RFC 3066 gave the user no option but to refer to the > source ISO standard, so users should and can continue to do so. So, you're saying that the ISO definition of "CS" as "Serbia and Montenegro" will continue to be valid, with that meaning, in a language-tag? > After this response, I will not waste my time any further on this > foolishness. The foolishness is your insistence on trying to tie the definitions to a localization issue. While definitions in some language can be localized, the definitions can also be used directly, and indeed must be used in some form into to make sense of the shorthand codes that represent the definitions. The issue isn't about localization at all; it's about having continued accessibility to the definitions in at least as many languages as is currently the case. > > I'm willing to postpone the discussion > > (other problems with the proposed registry format dictate > > a broader solution which could easily have provision for > > an arbitrary number of descriptions). > > I strongly object to the suggestion that progress on this draft be > delayed to deal with this non issue that caters to implementation issues > that are well beyond the scope of either RFC 3066 or its proposed > replacement. Your characterization of the issue is inaccurate. No matter; let's deal instead with the issue of retaining the current meaning of sr-CS (Serbian as used in Serbia and Montenegro). How does the draft proposal retain the meaning of that valid RFC 3066/ISO 639/ISO 3166 language tag? > > No, you are overlooking the fact that a set of codes with > > no corresponding definitions is useless.

You'd still have a versioning problem because of the multiple meanings of "CS". Trying to sweep any of those multiple meanings under the rug (by declaring them "not valid") isn't going to make them go away; what about existing data using the current meanings? I doubt you'd expect every software vendor... etc. The only way to solve a versioning problem is with an appropriate versioning solution. > > > Display names for languages and countries are not within the scope > of > > > RFC 1766 or RFC 3066.

I haven't specifically discussed "display names"; that is your assertion, and not my basis for objection. I refer to the definitions and the need to map to and from those definitions at either end of the communications channel. Whether or not that happens by "display" is incidental to the issue of the number of languages that the definitions are provided in. > > No, I am complaining about removal of internationalized > > definitions associated with language tag components. > > No definitions are removed.

So, again I ask for confirmation; the ISO definition of "CS" as "Serbie et MontÃnÃgro" will not be removed from use with that meaning in language tags by the draft proposal? > > "Localization" would be translation of the French definition > > into some other language.

No, presentation is incidental. I have repeatedly referred to the definitions, and the draft proposal's effect of removing 50% of those definitions. > Please accept that your arguments on this > matter are empty.

Considered, yes, of course. But not rubber-stamp approved. And if not approved, not usable. And unlikely to be approved if incompatible with core Internet protocols. _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
