The CONTACT field

This field shall contain a contact profile of someone willing to be contacted about details of the dataset (ideally an ORCID ID, RESEARCHER ID, potentially LinkedIn, Academia.edu profile etc.; up to 3 contacts can be provided).

This information is not equivalent to a corresponding author, but should be a stable point of contact at the main institution(s) involved. To simplify everyone’s data protection needs, we need it to be a link to a profile, rather than something directly personally contactable like an email address.
