3. Summary of RM-ODP
ISO/IEC Standards ISO/IEC 10746-2 Reference Model for Open Distributed Processing - Foundation ISO/IEC 10746-3 Reference Model for Open Distributed Processing - Architecture ISO/IEC FCD 15415 Reference Model for Open Distributed Processing - Enterprise Viewpoint
Features of RM-ODP A Modeling Methodology Consists of 5 Viewpoints Terms are clearly-defined
Five Viewpoints Enterprise Viewpoint - Institutional arrangement as contracts Information Viewpoint - Semantics of and relationship among information items Computational Viewpoint - Separation of functions and definition of interfaces among them Engineering Viewpoint - Mechanism to realize above Technical Viewpoint - Choice of technologies
Features of Enterprise Viewpoint Top Level Viewpoint of Five Viewpoints Business-oriented Viewpoint A Domain is regarded as a Community A Community has Enterprise Objects Community and Enterprise Objects have their own Roles and Processes Obligation, Prohibition, Permission and Authorization are defined as Policies

4. Outline of the Project
Organizers INTAP JAHIS MEDIS
Primary Objective of the Project by March, 2001 To Develop Preliminary version of J-HI-REM
Goals of the Project To describe the Japanese Healthcare System in terms of RM-ODP Enterprise Language To evaluate the usefulness of RM-ODP To standardize Japanese Health Informatics To harmonize with International Standards ISO/TC215, HL7, DICOM, OMG Healthcare DTF etc especially with HL7 RIM To make a guideline for the development of RM-ODP Enterprise Model
Scope of the Model Medicine only Middle-size Hospital only c. 300 beds National Health Insurance only Health Medicine Social Welfare Scope
Modeling Approach 1. To Analyze Business Flow in Hospitals 2. To Abstract Sub-communities and Enterprise Objects 3. To Abstract Roles, Processes 4. To define Policies
Overview of JHIREM Hospital Community consists of Ward, Outpatient, Radiological, Laboratory, Pharmaceutical Accounting and Reception Subcommunities Enterprise Objects are Patients, Physicians, Nurses, Radiological Technologists, Clinical Technologists, Pharmacists, Receptionists and ODP System
Hospital Community Hospital Community Ward Dept. Outpatient Dept. Radiological Dept. Laboratory Dept. Pharmaceutical Dept. Accounting Dept. Reception Dept. Dept: Department or Sub-community
Enterprise Objects in the Community Hospital Community Patient Physician Nurse Radiological Technologist Pharmacist Clinical Technologist ODP system Receptionist
Future Themes To Refine the Enterprise Model To apply to larger hospitals and smaller clinics To extend beyond Medical Field To add Sub-communities such as Surgery department To add Objects such as Medical Records, Medical Equipment and Medication To develop Viewpoints other than the Enterprise Viewpoint To harmonize with HL7 RIM
