An overview of ontology based approach to organize the metadata for grid database

Abstract

Grid is a promising application infrastructure that promotes and facilitates the sharing and collaboration in the use of distributed heterogeneous resources through Virtual Organization (VO). The Semantic Grid refers to an approach to Grid computing in which information, computing resources and services are described in standard ways that can be processed by computer. This makes it easier for resources to be discovered and joined up automatically, which helps bring resources together to create virtual organizations. Semantic grid allow user to discover data based-on service. Data Publication is the process by which data sets and their associated attributes are stored and made accessible to a user community. A gap arise when data is published by its metadata that focused on the context of its data semantic, on the other hand, normally discovery process is focused to the service concept. This paper gives an overview that can be used as an overview approach to solve this gap. Our approach focuses on the usage of specifics of descriptive information about services, and relevant information objects as classification scheme. We also discuss the possibility of ontology usage for metadata organizing.
