Dear Slava
Many thanks for your reply, I actually had a look at your presentation and prototype FE approach. I was wondering because we are in the planning phase of using Dataverse as RD repo in my Uni. the problem is that many data sets are gathered from 3ed parties, come with Non-disclosure agreements, and need special care to manage.
currently, my only possible approach to designing the architect is to have 2 instances of Dataverse, but one of them behind a VPN and some security measures to access the files via proxy for instance. leaving the other instance for OA and self depositing.
I think Tags solves this issue specifically, that is why I was very interested to learn if it came to light yet.
