| Summary: | Large grid systems are characterized by the scale of resources and users associated with
high heterogeneity and dynamism, which entails a resource discovery (RD) system that is
able to cope with this condition. This paper proposes a novel semantic description and
registration framework for large grid RD systems. The description model consists of a set
ontologies and services. Ontologies are used as a data model for resource and application
description, whereas the services are to accomplish the description process. The registration
model is also based on ontology, where nodes of the resources are classified to some
classes according to the ontology concepts, which means each class represents a concept in
the ontology. Each class has a head, which plays the role of a registry in its class and
communicates with the other heads of the classes during the discovery process. The paper
shows how the framework satisfies grid RD features such as scalability, decentralization,
dynamism and interoperability. |
