DATA Use Agreements are contractual documents used for the transmission of non-public data and subject to a certain limitation of their use. Overall, DUAS can be either incoming (the UI receives data from an external entity) or from (data that is housed in the UI is shared with an external entity). The UI Research Data Policy is also available. When requesting data from an external institution or organization, it is the responsibility of that organization to determine whether a DUA should be executed before release. Some governmental organisations (Confederation and Länder) have an application procedure which must be concluded before negotiations begin.
