DEVELOPMENT OF D＆D SUPPORT SOFTWARE

这个项目的目的是实现数据和描述（ddd）的支持软件。ddd的想法来自于统计数学研究所之前的一个项目，叫做“D&D”。正确地组织数据并提供足够的描述以供以后使用是很重要的。ddd规则提供了这样一种组织方式。ddd规则本身已经被实现为XML（可扩展标记语言）的DTD（文档类型定义）。这意味着ddd的任何实例都采用XML实例的形式。这是为ddd开发各种类型的支持软件的一个优点，因为XML是创建WEB页面的关键标记语言，因此基本的浏览器和软件已经准备好使用了。本项目开发了两个支持软件。一个是ddd的浏览器，称为ddd浏览器。另一个是Splus的导出系统，这是一个专门用于数据分析的软件。这些软件可通过http: //www.stat.math.keio.ac.jp/DandD向公众提供

The aim of this project is to implement support softwares for Data and Description (DandD). The idea of DandD comes from the previous project in the Institute of Statistical Mathematics, called "D&D". It is important to organize data properly with its enough description for later use. DandD rule provides a way of such an organization.The DandD rule itself has been implemented as a DTD (Document Type Definition ) of XML (EXtensible Markup Language). It means that any instance of DandD takes form of XML instance. This is an advantage of developing various types of support softwares for DandD, since XML is a key markup language for creating WEB pages, so that basic browsers and softwares had been already ready for use.Two support softwares has been developed in this project. One is a browser for DandD, called DandD browser. The other is an export system for Splus, a software specific for data analysis.Such softwares are available for public throughhttp : //www.stat.math.keio.ac.jp/DandD
