"On the effective construction of catalog databases for Japanese classical literature based on the new model -Case study of the reconstruction of microfilm catalog data to multimedia data-"

日本古典文学资料的一个特点是多媒体。然而，由于研究人员可利用的数据库大多是目录数据，因此需要学术信息设施提供全文和图像等内容服务。为了满足这些要求，国立日本文学研究所开始了数据库重建的新研究。为了在数据库中积累丰富的数据，为小型组织提供充分的服务，“数据标准化”和“数据独立于系统”是关键词。在本研究中，我们选择以SGML（标准通用标记语言）作为标准化的基础来构建一个新的数据库系统。本研究的独特之处在于我们将目录和文本都视为复杂的结构文本，并引入SGML作为数据描述库。基于这个概念，我们执行了一个实验，包括创建文本数据，并使用一个工具为不同性质的多个数据集提供服务。具体来说，我们已经1)为两种类型的现有数据创建了DTD（数据类型定义），2)将这些数据转换为SGML数据，3)使用字符串搜索工具测试生成了一个数据库系统，4)将SGML数据转换为Tex文件以编辑图书。我们正在使用SGML进行数据库重建，以应对多媒体时代。这个重建项目正在正确的轨道上。我们还对日本古典材料进行了数字图像开发。目录数据将图像文件位置作为标签中的属性，以连接目录和图像数据。我们将开始新的软件开发来支持这些图像数据。

A feature of data in Japanese classical literature is essentially multimedia. However, as most of the databases that are available to researchers are catalog data, academic information facilities are required contents services such as full-text and images. To come up these requensts, the National Institute of Japanese Literature started new study of database reconstruction. In order to accumulate variety data in databases and to provide adequate service in a small organization, "standardization of data" and "data independent from the system" are the key words. In this study, we chose for constructing a new database system with SGML (Standard Generalized Markup Language) as the basis for standardization.The peculiarity of this study is that we consider both catalog and text as complicate structural texts, then SGML is introduced as a data description base. Based on this concept, we have performed an experiment involving the creation of text data and servicing multiple data sets of different netures with a single tool. Specifically, we have 1) created DTD (Data Type Definition) for two types of existing data, 2) converted these data to SGML data, 3) test-produced a database system using a string search tool, 4) converted SGML data to Tex file to edit books.We are undertaking reconstruction of databases using SGML to cope with the multimedia age. This reconstruction project is on the right track. We have also made a digital image development of Japanese classical materials. The catalog data possesses image file location as an attribute in a tag to connect catalog and image data. We will begin new software development to support these image data.
