I think being able to draw from external vocabularies would be a desirable approach rather than expanding the existing vocabulary.
I agree that it is unclear in MODS how one could express the relationship between different files being deposited in a repository as one digital object. We currently do not record any information about a dataset if it is being deposited with the research publication in our repository. The MODS simply describes the research publication. While we could probably add a <note> that mentions the dataset, I don't think that is granular enough for enabling discovery.
