GSFL: A Workflow Framework for Grid Services
The Open Grid Services Architecture (OGSA) tries to address the challenge of integrating services spread across distributed, heterogenous, dynamic "virtual organizations" using the concepts and technologies from both the Grid and Web service communities. The Web service community has realized that Web services can reach their full potential only if there exists a mechanism to describe the various interactions between the services and dynamically compose new services out of existing ones. This is true in the case of Grid services as well.
The Grid Services Flow Language (GSFL) is an effort to examine technologies that address workflow for Web services and leverage this technology for Grid services. This project contains both an XML schema definition for the specification of workflow in Grid environments and a reference implementation of the Workflow engine for use in the Open Grid Services Infrastructure (OGSI).
