Grid resources might provide a foundation for meeting the increasing demand for storage capacity and computing power in next-generation SDIs. This article gives an overview of the current state of research regarding combinations of grid service and OGC Web Service (OWS) technology. Because of the inherent complexity of grid computing it is necessary to simplify the access of grid resources for potential users. Therefore, the article describes approaches developed in the GDI-Grid project to bridge architectural gaps between both technologies without changing the well-known service interfaces specified by the OGC. After highlighting fundamental differences of grid infrastructures and SDIs, suitable methods for grid-enabling OGC processing (i.e. Web Processing Service) and data services (i.e. Web Feature Service, Web Coverage Service) are shown.
