I have already been working on relationships between individual language, macrolanguage, and collective language group codes. I am down to the problem codes (I have some 350 to go on the 600+ code elements that I could not map via automated queries). Then I need to verify the draft mappings. Perhaps I will be through that in the next 2 weeks (it is not the only project on my plate.) I will send those to you at that point.

I am also very interested to read about the MARC code set in XML. I have just started modeling an RDF-based expression of ISO 639. I have looked into SKOS in this regard, as well. I'd be interested in working with you all on that (sooner rather than later). I just downloaded the languages.xml file, so I will look into that and take up that conversation separately with you.

Re: decision required: "other" collections

Having reread the recent posts on this issue, I think that Peter has been
convincing in his arguments that the distinction between Other and
Languages is no longer clear, since we have added languages that once were
only under a collective language group. I am prepared to accept the
suggestion that we change the names of those called (Other) to Languages.
I would be in favor of making available documentation that shows which
individual languages have their own codes under the language groups in ISO
639-2 and which use the collective code. We already have documented the
individual languages that use a collective code in MARC, but we don't show
under a collective code those languages that fall in the group that have
their own codes.

We have recently made the MARC language code list available in XML which
will allow us to transform the list to more expressive syntaxes. Since the
same set of codes is used in MARC, this should help us for the 639-2
documentation. We (i.e. my office at LC) are looking into establishing
registries for some of our controlled lists of values, perhaps using
semantic web technologies, such as RDF/OWL or SKOS. Relationships between
entities in the list are an important feature of these schemes-- e.g.
showing which languages are subparts of another more general name.

Obviously we will need to coordinate this work with the ISO 639 as
database effort. If we want to document the individual languages that have
their own codes and are not part of the "remainder group", we may need
some help identifying these. Will SIL be able to help with this sort of

So if we were to change the (Other) to Languages, would that help with the
IETF concerns?
