Development of CDA authoring tool: CDA studio

This paper describes the CDA authoring tool (CDA studio) which can be used to develop CDA (clinical document architecture) documents in clinical environment. It provides easy-to-use interface for editing CDA templates and connecting legacy information system. In this paper, we describe the architectures and functions of CDA studio and its 3 modules: the designer, the mapper, and the generator. The designer provides the junctions to display tree format of CDA schema and generates a sample CDA document. The main role of mapper is map between the CDA elements and the field of legacy information table. The generator produces CDA documents for local clinical environments by integrating real data from the existing information system.
