Health-Level (HL) 7 message semantics allows effective functional implementation of Electronic Medical Record (EMR)--encompassing both clinical and administrative (i.e. demographic and financial) information--interchange systems, at the expense of complexity with respect the Protocol Data Unit (PDU) structure and the client-side application architecture. In this paper we feature the usage of the Extensible Markup Language (XML) document-object modelling and Java client-server connectivity towards the implementation of a Web-based system for EMR transaction processing. Our solution features an XML-based description of EMR templates, which are subsequently transcribed into a Hypertext Markup Language (HTML)-Javascript form. This allows client-side user interfaceability and server-side functionality--i.e. message validation, authentication and database connectivity--to be handled through standard Web client-server mechanisms, the primary assumption being availability of a browser capable of XML documents and the associated stylesheets. We assume usage of the Internet as the interchange medium, hence the necessity for authentication and data privacy mechanisms, both of which can be constructed using standard Java-based building blocks.
健康级别（HL）7消息语义允许有效地实现电子病历（EMR）功能，该功能涵盖临床和管理（即人口统计和财务）信息交换系统，但代价是协议数据单元（PDU）结构和客户端应用程序架构的复杂性。在本文中，我们重点介绍了使用可扩展标记语言（XML）文档对象建模和Java客户端-服务器连接来实现基于Web的EMR事务处理系统。我们的解决方案的特点是基于XML的EMR模板描述，随后将其转录为超文本标记语言（HTML）-JavaScript表单。这允许通过标准的Web客户端-服务器机制处理客户端用户界面能力和服务器端功能，即消息验证、身份验证和数据库连接，主要假设是存在能够处理XML文档和相关样式表的浏览器。我们假设使用互联网作为交换媒介，因此需要身份验证和数据隐私机制，这两者都可以使用基于Java的标准构建块来构建。
