charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable Peter, I'm not sure there is an ideal solution, so this is probably as good as any= . I had thought of an analogy involving French French and Canadian French, an= d what if they were considered different enough that they had discrete 639 = codes, and each had the name "French (xxx)" but one also had the name "Fren= ch", implying that it was the "one true French." But that's a bad example, = partly because the two Male languages have nothing in common except the nam= e, and probably for other reasons as well. So I have no issues with how Isu and Male were handled. Language categoriza= tion is hard, and naming things is hard. -Doug Sent via the Samsung Galaxy S22 Ultra 5G, an AT&T 5G smartphone Get Outlook for Android ________________________________ From: Peter Constable Sent: Monday, April 20, 2026 8:11:38 AM To: Doug Ewell ; ietf-languages@ietf.org Subject: RE: Records and registration forms for April 2026 ISO 639 changes Doug: The ISO 639 MA deliberated what to do in cases in which a reference name in= cluded a parenthesized distinguishing label to avoid duplicate names, but (= for whatever reason) the non-parenthesized part of the name was changed, wi= th the result that there was no longer any name collision. There was concer= n to minimize confusion, though confusion could arise for different reasons= . We landed on this: - do not retain disambiguating qualifiers in language reference names if a = change to another language reference name removes ambiguity - however, add the old language reference names with disambiguating qualifi= ers as alternate names The second point was added to accommodate people who might have seen qualif= ied names like "Male (Papua New Guinea" vs. "Male (Ethiopia)" in the past, = and then now seeing only "Male" and being confused about which of the two t= hat refers to. What do you see as confusion created by this approach? If there are suggestions as to how such cases might be handled differently,= those can be considered. Peter Constable -----Original Message----- From: Doug Ewell Sent: April 19, 2026 11:02 PM To: ietf-languages@ietf.org Subject: [Ietf-languages] Records and registration forms for April 2026 ISO= 639 changes Below are proposed records and registration forms for changes made this pas= t week by ISO 639/MA, presented in the order they are listed in the April 2= 026 Quarterly Newsletter (referenced in each registration form). Possibly of note with these changes is that, in certain cases where two lan= guages have names of the form "language (region)", where the regions are of= course different, the MA has begun assigning one of them a reference name = of the form "language", without a qualifying parenthesized region, while ke= eping the region-qualified name as an additional name. One example is that = previously, [mdc] "Male (Papua New Guinea)" and [mdy] "Male (Ethiopia)" exi= sted, but now [mdy] additionally has the reference name "Male". (The other = instance here is "Isu".) I feel this approach will create confusion, but it is the MA's decision to = make, and since the names are ISO's and are not duplicates, we need to add = them to the Registry. Please review the 16 new and changed entries below and send any comments to= the list.

Peter,

I'm not sure there is an ideal solution, so this is probably as good as any= .

I had thought of an analogy involving French French and Canadian French, an= d what if they were considered different enough that they had discrete 639 = codes, and each had the name "French (xxx)" but one also had the = name "French", implying that it was the "one true French." But that's a bad example, partly because the two Male l= anguages have nothing in common except the name, and probably for other rea= sons as well.

So I have no issues with how Isu and Male were handled. Language categoriza= tion is hard, and naming things is hard.

—Doug

Subject: RE: Records and registration forms for April 2026 ISO 639 c= hanges
 
Doug:

The ISO 639 MA deliberated what to do in cases in which a reference name in= cluded a parenthesized distinguishing label to avoid duplicate names, but (= for whatever reason) the non-parenthesized part of the name was changed, wi= th the result that there was no longer any name collision. There was concern to minimize confusion, though= confusion could arise for different reasons. We landed on this:

- do not retain disambiguating qualifiers in language reference names if a = change to another language reference name removes ambiguity
- however, add the old language reference names with disambiguating qualifi= ers as alternate names

The second point was added to accommodate people who might have seen qualif= ied names like "Male (Papua New Guinea" vs. "Male (Ethiopia)= " in the past, and then now seeing only "Male" and being con= fused about which of the two that refers to.

What do you see as confusion created by this approach?

If there are suggestions as to how such cases might be handled differently,= those can be considered.

Subject: [Ietf-languages] Records and registration forms for April 2026 ISO= 639 changes

Below are proposed records and registration forms for changes made this pas= t week by ISO 639/MA, presented in the order they are listed in the April 2= 026 Quarterly Newsletter (referenced in each registration form).

Possibly of note with these changes is that, in certain cases where two lan= guages have names of the form "language (region)", where the regi= ons are of course different, the MA has begun assigning one of them a refer= ence name of the form "language", without a qualifying parenthesized region, while keeping the region-qualified name= as an additional name. One example is that previously, [mdc] "Male (P= apua New Guinea)" and [mdy] "Male (Ethiopia)" existed, but n= ow [mdy] additionally has the reference name "Male". (The other instance here is "Isu".)

I feel this approach will create confusion, but it is the MA's decision to = make, and since the names are ISO's and are not duplicates, we need to add = them to the Registry.

Please review the 16 new and changed entries below and send any comments to= the list. The review period ends Monday, May 4, 2026.
