It refers to the process of locating a machine-processable description of a Web service-related resource that may have been previously unknown and that meets certain functional criteria. It involves matching a set of functional and other criteria with a set of resource descriptions.
The Automatic Resource Discovery may also support job scheduling and allocation by integrating real-time statistical data from the endpoints with static data such as network topology and backing storage capacity. The same repository could be used to store other Grid information such as SLAs, policies etc, and could be used as a general extensible data repository for the various components of the Grid infrastructure.
Semantic annotation techniques can be used to annotate SLA and policy requirements. Resource discovery will be based upon an RDF data repository, in order to provide a generic search capability to locate resources available in the network. The search results are based upon static descriptions of GRID components, such as network topology, as well as searching over dynamic values, such as current compute load.
