Abstract

Document Type Definitions (DTDs) are widely used to describe the structure of XML documents. The Clinical Document Architecture (CDA) and the Guideline Element Model (GEM) are examples from the healthcare domain. XML schemas provide another way to describe types of XML documents. In this paper we aim to advocate XML schemas from the perspective of an ANSI standard, the XML based CDA from HL7 (ANSI/HL7 CDA R1.0-2000). It turned out that existing tools do not fully exploit the knowledge contained in DTDs and XML schemas. The result of this study is a set of tools (DTD to XML Schema translator, DTD and XML schema browser, XML editor), which can be downloaded from the official W3C site and which work with any DTD and XML schema.

摘要

文档类型定义（DTD）被广泛用于描述XML文档的结构。临床文档架构（CDA）和指南元素模型（GEM）就是医疗保健领域的例子。XML模式提供了另一种描述XML文档类型的方法。在本文中，我们旨在从ANSI标准（基于XML的HL7 CDA（ANSI/HL7 CDA R1.0 - 2000））的角度倡导XML模式。结果发现，现有工具并未充分利用DTD和XML模式中包含的知识。本研究的成果是一组工具（DTD到XML模式转换器、DTD和XML模式浏览器、XML编辑器），这些工具可以从W3C官方网站下载，并且可与任何DTD和XML模式配合使用。
