An Open Source Toolkit for Grid Resources Scheduling in Digital Library

A number of tools have been developed to support application development in Grid Services architectures. But most of these efforts have focused on low-level support for management and execution of Grid services, management of Grid-enabled resources, and deployment and execution of applications that make use of Grid services. This paper describes an open-source toolkit,called Introduce, that supports easy development and deployment of Web Services Resource Framework (WSRF) compliant services. And it emphasizes how to realize grid resources scheduling through the toolkit-Introduce,connected to the project of research on the grid application model of digital library.
