If you intend to provide personal data at your Research Data Center (RDC), you can simplify matters for subsequent users by offering an instructional document, such as Usage Regulations for Campus Files of the FDZ at the IQB, for example.
You can provide users with a suggested citation to support the correct reuse of the research data you provide. You can either offer general recommendations (as done by FDZ am bibb) or provide complete templates (e.g. SHARE).
Your terms and conditions can be either linked as a separate document on your website or implemented directly, as seen on the Archive for Spoken German’s website.
The degree of necessary data anonymization essentially depends on the access method. FDZ DZHW illustrates this clearly on its homepage and presents various anonymization measures using a certain case as an example.
