The German Federal Ministry of Education and Researchopen in new window is funding the Medical Informatics Initiativeopen in new window with the aim of making routine data available digitally, reliably and quickly for medical research. University hospitals have founded consortia with partners such as research institutions and other companies to create the conditions for research and patient care to share their data across sites. Data Integration Centers (DIC) have been established at the university hospitals and partner institutions to create the technical and organizational conditions for data exchange between patient care and medical research.

The Data Sharing Framework (DSF) was developed within the HiGHmed consortium of the Medical Informatics Initiative and is now funded as an independent project by the German Federal Ministry of Education and Research within the Medical Informatics structure as DSF Communityopen in new window.

The DSF is a concept for a secure middleware to distribute data sharing processes, aiming to extract, merge, pseudonymize and provide data stored in multiple distributed DICs. A researcher can use the DSF for example to submit feasibility queries to several DICs and thus has the opportunity to obtain sufficient data from different locations for his or her research. By using international standards such as FHIR and BPMN 2.0, the problem of heterogeneous data models, primary systems, architectures and federated legislation between DICs can be solved. The aim is to enable secure and syntactically-, semantically- and process-interoperable data exchange across organisational boundaries.

The DSF is a secure communication infrastructure, that (1) scales with communication relationships, (2) orchestrates processes and instances, (3) separates execution logic from program code, (4) enables automated and user-centeric process steps ​(5) and can be used for heterogeny structures.
