Research Data warehouse

The Research Data Warehouse is powered by the DISQOVER system and functions as index on all data that is stored in DataHub. It can be used to search across your own data, but also (meta)data of others. 
The idea is based on the FAIR principles, where all metadata is Findable, but only data for which you are authorized is Accessible. 

Interesting data sets that are not accessible by you, do contain a Contacts with information on the data uploader / owner.

Before you start!

In order to use the DataHub infrastructure, make sure that you are connected to the UM- or MUMC-network. Either physically or via VPN.
