As a researcher, I need more language options to better describe my data

[jggautier]

A Harvard Dataverse user asked that more languages be added to the vocabulary used for the language metadata field in the dataset metadata edit form, so that depositors are better able to describe what language their data is in. (https://help.hmdc.harvard.edu/Ticket/Display.html?id=259958)

Specifically, he asked that we add "Mixtepec Mixtec", which is the language that his data is in. Mixtepec Mixtec is in the ISO 639-3 vocabulary (ISO language code is "mix") and not among the 185 ISO 639-1 vocab terms that Dataverse uses as of version 4.8.4.

More broadly, he asked that Dataverse allow depositors to add any of the 7000+ languages in the ISO 639-3 language vocab.

The user agreed that as a first step we could simply add the one term he needed. We would need to update the citation metadata block: #4642

We could consider later, maybe in a different issue, how to allow depositors to specify one or more of the 7000+ languages in ISO 639-3.
