ABSTRACT
"Grid is as an emerging technology for enabling resource sharing and coordinated problem solving in dynamic multi-institutional virtual organizations. In the grid environment, resources may belong to different institutions, have different usage policies and pose different requirements on acceptable requests.
one of the fundamental operations needed to support location independent computing is resource discovery .It is the process of locating relevant resources based on application requirements of a user.
The description of a resource is essential for automated resource discovery and search, selection, matching, composition and interoperation, invocation and execution monitoring; different middle-ware specifies different rules for describing a resource. Hence, the information gathered from these diverse sources tends to be semantically heterogeneous and needs to be correlated.
Efficient resource discovery needs uniform unambiguous resource description. To date there is no universal resource description language common to all state of art grid middleware. Different grid middleware systems have different methods of resource description and it is not yet known how well these can interoperate. Hence, there is a need to utilize semantic matching of these resource descriptions."
