Feature Request: Social Science external controlled vocabulary

[CB-HAL]

Data Documentation Initiative (DDI) is the international metadata standard for social science, DDI offers also a set of controlled vocabularies. The social science metadata block of Dataverse uses the DDI metadata fields, also the export and import utilities. But the controlled vocabularies are not in use, DDI CV are offered in the machine-readable format SKOS https://vocabularies.cessda.eu/?f=agency:DDI%20Alliance and Skosmos https://vocabularies.cessda.eu/v2/api-docs. So, it would be a good idea to integrate the DDI CV as external vocabulary service in Dataverse.
