I would like to know the motivation from users who request my data, can users provide this information?

Unfortunately, it is currently not possible for users who submit an access request to include their motivation for requesting access to your data files. If you require such a motivation in order to evaluate the request, you can specify this in the ‘Terms of Access for Restricted Files’ which is a dedicated field in the ‘Terms’ tab. You can, for instance, ask users to send their motivation to you by email before you evaluate their requests. The Terms of Access will be explicitly shown to users requesting access to the data.
