OBJECTIVE: This is designing the part of Electronic Medical Record using HL7 Development Framework and Reference Information Model to realize the building medical standard data model for sharing medical record between heterogeneous hospital systems.

METHODS: The process used development of HL7 specifications consists of the following seven activities: 1.Project initiation. 2.Requirements Documentation. 3.Specification Modeling. 4.Specification Documentation. 5.Specification Approval. 6. Specification Publication. 7.Implementation Profiling. Each activity is briefly described in the subsections that follow and described in detailed in the methodology chapters that follow this introduction.3. Result. The steps, after 4 step, needs to standardized the results. So we didn't followed that steps1).

RESULTS: We got the diagrams at each steps of the HDF methodology: 1.A dynamic description. 2.A static description of the concepts involved in the business process. 3.A Use Case model which identifies the system involved in the actual HL7 data/information exchange1).

CONCLUSION: It was confirmed that HL7 RIM could take in the domestic demands of medical records, and concrete methodology was applied in practice. It can be a good reference for the hospitals constructing new information system and for the enterprises developing medical information systems to apply the HL7 version 3 to their works.
