When a workspace is created, the e-mail address of a responsible person must be specified. This person will be contacted at the end of the retention period in order to clarify how the archived research data should be handled. As archived datasets can be retained for up to 15 years, the responsible person and the e-mail address should be chosen carefully. RADAR recommends the use of functional addresses (e.g. firstname.lastname@example.org) instead of personal e-mail addresses.
