1) Resource Naming and Representation
The majority of searchable resources on the World-Wide Web are text-based entities (Web pages) encoded in HTML format. These entities can be identified and addressed under a common, universal naming scheme (URI). In contrast, there is a wide diversity of searchable “entities” on the Grid with different functionalities, roles, semantics, representations, hardware resources, sensors, network links, services, data repositories, software components, patterns of software composition, descriptions of programs, best practices of problem solving, people, historical data of resource usage, virtual organizations. Currently, there is no common, universal
naming scheme for Grid entities.
