An RDF-based mediator for health data interoperability

Abstract

In this paper the authors propose and describe a Resource Description Framework (RDF)-based mediator designed to solve the health data interoperability problem that exists among heterogeneous health information systems (e.g., Electronic Health Records). The RDF-based mediator framework has three main components: (1) the Synonym Dictionary (SD) that can be used to map metadata semantics, (2) the CXTR module that can translate source XML-based health documents into RDF-XML format, and (3) the CRTX module that can translate an RDF-XML document into a target XML-based health document. The proposed mediator is expected to make health information exchange more efficient.
