Using a Semantic Network Application as an Enhanced Metadata Repository

As part of the German Medical Informatics Initiative, data integration centers have been established to consolidate clinical data for further research. At the University Hospital of Gießen a central FHIR repository acts as the data core of the data integration center. To allow researchers efficient navigation within the data sets, a semantic network application from neuropathology has been reused as an enhanced metadata repository. First results demonstrate the feasibility of the approach and show directions for further improvement.
