Filed Research on Global Flow of Scientific Information -- Towards the Systematization of Scientific Database

国家科学信息系统中心（NACSIS）自1987年以来一直为研究人员提供数据库服务，并开展科学数据库建设项目。随着科学研究日益国际化，与科学数据库有关的活动也应国际化。其中，向外国研究人员提供日本的科学信息，与外国学术机构合作建设和服务数据库是重要课题。基于这一认识，本研究计划调查世界科学数据库技术和服务方案的发展趋势，具体有以下三个专题：（1）建立和分发全文数据库，特别是SGML格式的数据库，这种格式似乎已占主导地位，（2）网关系统的技术和体制问题，这种系统将有效地连接各国的数据库系统，（3）电子图书馆，它的概念是将数据库和图书馆与先进的信息技术结合起来。与此密切相关的主题还包括：（4）外国研究者对日本科学信息的需求;（5）信息和数据库的国际标准;（6）通过组织国外高校图书馆参与NACSIS编目系统，建立面向全球的日本科学文献联合目录数据库，并将调查分析结果反映在NACSIS今后的研究和服务发展中。并主要通过NACSIS出版物与科学信息相关人员共享。

National Center for Science Information Systems (NACSIS) has been operating a databases service for researchers since 1987, and also conducting the projects of constructing scientific databases. As scientific research become more internationalized, the activities related to scientific databases should also be international. Among the important topics for them are the provision of Japanese scientific information to foreign researchers, and the construction and service of the databases in collaboration with foreign academic institutions.Based on the perception, this research project was planed to investigate the world trend in technology and servicing scheme for scientific databases with the three specialized topics as follows : (1) construction and distribution of full text databases, especially in SGML format, which appear to become dominating, (2) technical and institutional problems with gateway systems, which would be effective in linking the database systems of various countries, (3) electronic library, which is conceptualized as an integration of database and library with the advanced information technology.The following themes are also included, as are closely related with the above : (4) demand of Japanese scientific information by foreign researchers, (5) international standards on information and databases, (6) construction of a union catalog database for Japanese scientific materials on an global bases, which would be attained by organizing foreign academic libraries as the participant of the NACSIS cataloging system.The results of the survey and analysis will be reflected in NACSIS future development on research and services, and also be shared by the people concerned with scientific information mainly through NACSIS publications.
