Peter:
In this case I don't believe that ber in MARC is considered to include all Berber languages; the caption "Berber (Other)" is what is used in MARC. There is a distinction between our usage of "XXX languages" vs. "XXX (Other)" where the former is a group code to cover all languages in that group, while the latter is intended to cover what we are now calling remainder groups, i.e. the set of individual languages that do not have separate identifiers. Some on this committee will recall that several years ago when ISO 639-5 was being established we changed all those "XXX (Other)" names to "XXX languages" in 639-2 and 639-5. But the distinction still remains in MARC-- although I don't think that are other Berber languages that have their own coding in this case. 

The MARC Code List for Languages says the following about group codes:

"In addition to codes for individual languages, the list also contains a number of codes for language groups. While some individual languages are given their own unique code, although linguistically they are part of a language group, many individual languages are assigned a group code, because it is not considered practical to establish a separate code for each.

Group codes may be recognized by the fact that the name listed in association with the code does not represent an individual language, and includes either the generic term "languages" or the expression "(Other)," as opposed to names of individual languages which do not include these terms. For example:
myn Mayan languages
nic Niger-Kordofanian (Other)

These language group codes are generally established at a very broad level, e.g. South American Indian (Other) sai. Although some South American Indian languages have their own unique codes, such as Mapuche arn and Aymara aym, all other South American Indian languages which have not been assigned a unique code, such as the Cumana language, are assigned the group code sai."

In this case, I don't think that creating a new macrolanguage entry for Berber would be disruptive to MARC; but I agree with Peter that rather than change the scope of Berber languages (in MARC called Berber (Other)), it is better to add a new entry. But only if we find it is needed.

In 639-5, collections are not assumed to be "exclusive" (i.e., encompassing only entities within the semantic range denoted by the name of the collection but that are not coded as individual languages). An important application of ISO 639-2 is use in MARC, and in that context collections are treated as exclusive, however. So, depending on the application context, [ber] may or may not be assumed to include every Berber language.

Btw, you refer to "smaller Berber dialects". We need to be careful with our terminology: dialects are not coded in ISO 639-1/-2/-3/-5; dialects are in scope for coding only in Part 6. Presumably in this case you meant "smaller, less-developed languages" or something along that line.

As for the question of a macrolanguage, in principle a "Berber" macrolanguage could be coded, but [ber] should not be re-defined to change its scope from a collection to a macrolanguage: that would constitute some narrowing of scope, which would be problematic. If a "Berber" macrolanguage were to be coded, then it would need a distinct alpha-3 ID.

But before coding a new macrolanguage, I'd question the need. In particular, I question that there is _one_ Berber language (the correspondent describes themself as a speaker of "the Berber language"). It's entirely possible that the 25 Berber languages currently coded in 639-3 over-differentiate, but I strongly doubt that there are no real language divisions. (The fact that there are significantly different orthographies in use across the family points to a lack of unifying factors.) That makes me inclined to think that this person is a speaker of one of the languages already coded.

That said, one thing that can help maintain vitality of threatened languages is unification of closely-related languages, either through a shared orthography or through more aggressive socio-linguistic engineering. Over time, that can result, effectively, in a new language; but in the short term a coded macrolanguage entity may be useful in that it captures the ambiguity of there being multiple distinct languages while at the same time attempts are being made to communicate in just one form. But, before we go coding new entities, we ought to see evidence that there's a socio-linguistic reality out there that we're coding--i.e., we shouldn't code something just because some party would _like_ that to be a reality or likes to _believe_ it is a reality.

Dear Rebecca, et al.,

The code [ber] is currently a collective designator under ISO639-2 for the smaller Berber dialects which are not otherwise coded. There are three individual ISO 639-3 languages in her list of Berber languages.

Please comment on his request for making a macrolanguage which includes the three languages plus the collective. If this is deemed to be a suitable candidate, I will request the appropriate forms to make the proposal.

Thank you for your help with this.
