Q:I understand that ‘5. Access Rights ’ has to be ‘embargoed access’ if contents have an embargo. Do I have to change this value to ‘open access’ after the embargo period has expired?

Yes, you do. Please change the value for ‘5. Access Rights’ to ‘open access’ after the embargo period has expired; however, you do not have to delete the ones whose dataType attribute in ‘12. Date’ or ‘35.4 Date’ is set ‘Available’.
