随着科学实验及其分析越来越自动化，对工作流管理支持的需求也在增加。已经开发了许多针对科学工作流的工作流管理系统。然而，它们主要是独立的系统，而忽略了许多科研团体已经在实验室信息系统（称为LIMS）中存储和管理实验数据。LIMS通常是基于网络的，允许研究人员插入和查看实验相关数据。在本文中，我们描述了Exp-WF，这是一个工作流管理模块，旨在纳入典型的LIMS中，以便工作流管理和LIMS的传统功能共存。科学家将实验的执行顺序描述为工作流模型。然后，Exp-WF会自动选择要执行的实验，并将它们分配给负责执行这些实验的人或机器。WF扩展了现有的工作流模型，使其能够处理科学实验工作流的特殊性. Exp-WF可以以一种非侵入性的方式并入现有的基于Web的LIMS中，通过使用servlet过滤器技术来观察用户操作并对其采取行动。Exp-WF使用基于代理的异步通信技术将任务分派到远程机器。
As scientific experiments and their analysis become increasingly automated, the need for workflow management support rises. Many workflow management systems tailored to scientific workflows have been developed. However, they are mainly stand-alone systems and ignore that many scientific research groups already store and manage experimental data in laboratory information systems, called LIMS. LIMS are typically web-based and allow researchers to insert and view experiment related data. In this paper we describe Exp-WF, a workflow management module that is designed to be incorporated into a typical LIMS such that workflow management and the traditional functionality of a LIMS co-exist. Scientists describe the execution order of experiments as a workflow model. Exp-WF then automatically selects experiments for execution and dispatches them to the people or machines responsible for performing them. Exp- WF extends existing workflow models to be able to handle the particularities of scientific experiment workflows. Exp- WF can be incorporated into an existing web-based LIMS in a nonintrusive way by using servlet filter technology to observe user actions and act upon them. Exp-WF uses agentbased technology with asynchronous communication to dispatch tasks to remote machines.
