Can we connect existing production grids into a world wide grid?

The World Wide Web has become a phenomenon that now influences our everyday life in any possible areas and disciplines. This paper investigates how a grid equivalent of the WWW, the World Wide Grid can be created. We define requirements towards a workflow-oriented computational World Wide Grid and propose a solution how current production Grids can be connected in order to form the technical basis of this infrastructure. A meta-broker concept and its utilization to achieve the highest level of parallelism by the created architecture in a user transparent way are explained
