By combining the grid computing idea with the semantic web they plan to "...we see the emerging semantic web infrastrucure as an infrastructure for grid computing applications."
Their main paper (now 8 month old):
Grid Computing Framework:
"The Open Grid Services Architecture (OGSA) is a proposed evolution of the current Globus Toolkit towards a Grid system architecture based on an integration of Grid and Web services concepts and technologies. Initial proposed technical specifications have been developed by the Globus Project and IBM, and are being put forward at the Global Grid Forum for discussion, refinement, and (we hope) eventual standardization."
