未来数字图书馆的发展方向之一——服务主导型数字图书馆

One of DL Developing Trends——A Service-orientated Digital Library

主要探讨服务主导型数字图书馆的体系结构、服务功能和相关技术及问题等。十几年来 ,数字图书馆的研究和发展 ,将形成数字图书馆三种主流模式即特种馆藏型模式、服务主导型模式和商用文献型模式 ;服务主导型数字图书馆的体系结构 :它以三种主要数字化资源为基础和由统一信息访问平台、网上参考咨询 (VRS)平台为两翼组成 ;统一信息访问平台主要解决异构平台的信息资源检索 ,向用户提供方便检索的统一界面 ,提供不同数字图书馆的互操作。网上参考咨询平台主要解决用户在访问数字图书馆时的疑问。这两个平台对一个实用的数字图书馆是不可缺少的 ,在系统结构上有些是相互渗透的。文中还探讨数字图书馆建设中相关的 10个问题。
