Ah, I understand more now. Thanks!
You're right. It looks like in the design of the Dataverse TSV file, the "required" column more specifically means that users creating and editing datasets will have to fill the required field as long as the metadata block is enabled in the collection. And I think we've always assumed that if the metadata block contains any required fields, the person managing the collections will enable the metadata block, or won't disable it, since they'd want people to fill the required fields.
That seems to not be true in your case, right? Have folks who manage collections in the
CUHK Research Data Repository disabled this metadata block? Or if that hasn't happened yet, do you think that they might disable it, and you want to prevent that from happening?
