Sharing health data for research purposes across data custodian boundaries poses technical, organisational and ethical challenges. In beginning to address some of the technical challenges, we describe a service oriented architecture for a proposed Health Research Data Network (HRDN). The HRDN architecture supports services to manage data access and use by(More)
