Knowledge-based Grids

Abstract

Grids tie together distributed storage systems and execution platforms into globally accessible resources. Data Grids provide collection management and global namespaces for organizing data objects that reside within a grid. Knowledge-based grids provide concept spaces for discovering relevant data objects. In a knowledge-based grid, data objects are discovered by mapping from scientific domain concepts, to the attributes used within a data grid collection, to the digital objects residing in an archival storage system. These concepts will be explored in the context of large-scale storage in the web, and illustrated based on infrastructure under development at the San Diego Supercomputer Center.
