Design of service registry for interoperable medical information system

The interoperable medical information system makes good use of medical information produced by hospitals. The development of an interoperable medical information system requires facilities that allow services to be queried, chosen, set up, and executed. In this paper, we propose a service registry design of an interoperable medical information system. As the core element of a medical information system, the service registry allows cooperative hospitals and medical institutions to publish their services to the central server, which users can then access to search for and utilize the registered services. To ensure that the registered service is valid and that the service information is correct, service registry monitors actively gets the latest information about services. The service registry design proposed in this study is based on the Microsoft.NET platform. The service registry´s website is published by Internet information services (IIS), thereby allowing non-local users to access the services through the Internet.
