Interoperability is a key issue in distributed health information systems. This paper presents the design and implementation of the Connection Service (CS) component of the HELIOS medical software engineering environment. An exchange message meta-model based on CEN TC251 recommendations and a message description language are proposed. Using this meta-model, the CS is able either to interpret messages expressed in a given syntax (e.g., EDIFACT, ASTM) and map them to the application objects or to automate the translation of the messages in another syntax. It is concluded that this meta-model approach contributes to the management of semantic heterogeneity.
互操作性是分布式健康信息系统中的一个关键问题。本文介绍了HELIOS医学软件工程环境中连接服务（CS）组件的设计与实现。提出了一种基于CEN TC251建议的交换消息元模型和一种消息描述语言。利用该元模型，CS能够解释以给定语法（如EDIFACT、ASTM）表示的消息并将其映射到应用程序对象，或者自动将消息翻译成另一种语法。得出的结论是，这种元模型方法有助于管理语义异质性。
