G. von Laszewski and D. Kodeboyina, "A Repository Service for Grid Workflow Components," Preprint ANL/MCS-P1256-0605, June 2005. [pdf]
As part of the Java CoG Kit we have defined a sophisticated workflow framework. This workflow framework projects an integrated approach towards executing tasks in Grid and non-Grid environments. One of the services needed is a convenient service to store, retrieve, and modify workflow components defined by the community similar to systems such as the comprehensive perl archive network. The availability of such a service will not only allow the definition of components useful for the greater grid community, but it will also be possible that it can be reused to support dynamically changing workflows managed by collaborative groups. In this paper, we present a simple extensible framework to design, build, and deploy a workflow repository service. This repository is intended to be used in ad-hoc Grids or in community Grids.
