Visionse-Sciencee-Science is about global collaboration in key areas of science and the next generation of infrastructure that will enable itGridflexible, secure, coordinated resource sharing among dynamic collections of individuals, institutions, and resources - what we refer to as virtual organizations

SKG2005

RequirementsThese visions require an infrastructure for flexible, coordinated resource sharingThey are about joining resources up, automatically, in order to do things that werent possible beforeWe wish to reuseData, Services, Knowledge, SoftwareAnticipated use and Unanticipated use

Semantics in and on the Grid

SKG2005

MotivationFuture visions of computing involve VirtualisationRaising the level of abstraction over scale and heterogeneity of resourcesThis requires automationSelf-managing, Self-configuring, Self-healingThis requires machine processable descriptions and contentThis requires semantics and knowledgeThis requires SKG2005 !
