...way of abstracting and mapping a workflow to a service in computational
grid environments. by using meta services, a workflow in a grid environment could adapt various service concepts such as grid
services, web services, and portal services without modification to the workflow. and the converted meta services could be
shared and reused...

...central concepts of the open grid service environment, which represents an abstract service stack
and was introduced to design workflow-based problem solving environments. so far, it has been used to model large-scale computational
finance problems as abstract workflows with meta-components and instantiate such workflows with different components based
on semantic matching. in this paper we continue by...

the workflow is managed in grid environments, it is processed effectively by using many grid resources. in this paper, we
present a workflow system which manages workflow operations in grid environments. the workflow model is divided into three...
