Design of Covid-19 observational data platform. In order for hospitals to link to the data platform, they need to make their clinical, imaging and lab data FAIR. Tools for data harmonization (FAIR-ification) are being shared between institutes. FAIR metadata (and in some cases FAIR data) and access policies are shared with the observational platform. This enables a search tool for researchers to determine what data resources are available at the participating hospitals. These data can subsequently be requested, and if the request is approved by a data access committee, the data will be provided, or information how the data can be accessed will be shared. In subsequent versions of the data platform, also distributed learning will be supported, so that data can stay at its location.
