Metadata management scheme based on semantic links for grid monitoring
Yang Guangwen · Journal of Tsinghua University(Science and Technology) · 2008
A metadata management scheme based on semantic links was developed to meet the vague grid monitoring requirements for users in the chinagrid supervision(CGSV) project.The heterogeneity and various ownerships of grid resources require logically modeling of the physical resources with monitoring metadata characterized by shaping specific monitoring metrics into several semantic dimensions.Metrics and semantic dimensions are further linked together across various resource models.This results in a semantic link network of grid monitoring metadata at the global level with a query mechanism based on semantic distance to locate monitoring metadata.Tests show that the semantic link registry for the chinagrid supervision project can handle more than 120 requests per second;thus,the scheme is effective and practicable.
