A Lightweight, Flexible, and Web-Based Approach to Supporting Workflow in Digital Libraries

该项目正在开发一种轻量级基础设施，用于将工作流服务部署到数字图书馆中，该数字图书馆可以根据用户的独特需求进行定制。这种工作流要求通常涉及分布在不同组织中的多个利益相关者，这些利益相关者必须协调他们的行动。事件消息传递系统、超媒体和基于Web的技术(如XML)的最新进展被用来创建一种轻量级工作流技术，以帮助数字图书馆的利益相关者协调他们共享的活动。这项技术旨在支持较低的准入门槛、多个计算平台，以及对采用该技术的单个组织具有一定程度的自主权。目前正在利用三个“现实世界”数字图书馆的工作流程对该项目的技术和技术进行评估：国家大气研究中心科学计算司门户网站、与地球系统教育数字图书馆有关的Jesse电子期刊和JIME电子期刊。

This project is developing a lightweight infrastructure for deploying workflow services into digital libraries that can be tailored to meet users' unique needs. Such workflow requirements typically involve multiple stakeholders distributed across different organizations who must coordinate their actions. Recent advances in event messaging systems, hypermedia, and Web-based technologies (such as XML), are being used to create a lightweight workflow technology to help the stakeholders of a digital library coordinate their shared activities. The technology is being designed to support a low entry barrier to use, multiple computing platforms, and a certain level of autonomy to the individual organizations that adopt it. Evaluation of the project's techniques and technology is being undertaken using the workflow processes of three "real-world" digital libraries: the Web Portal to the Scientific Computing Division of the National Center for Atmospheric Research, the JESSE electronic journal, associated with the Digital Library for Earth System Education, and the JIME electronic journal.
