Interoperation of world-wide production e-Science infrastructures

Many production Gridand e-Scienceinfrastructures have begun to offer services to end-users during the past several years with an increasing number of scientific applications that require access to a wide variety of resources and services in multiple Grids. Therefore, the Grid InteroperationNow—Community Group of the Open GridForum—organizes and manages interoperationefforts among those production Gridinfrastructures to reach the goal of a world-wide Gridvision on a technical level in the near future. This contribution highlights fundamental approaches of the group and discusses open standardsin the context of production e-Scienceinfrastructures. Copyright © 2009 John Wiley & Sons, Ltd.
