A Highly Available Grid Metadata Catalog

Abstract

This article presents a metadata catalog, intended foruse in grids. The catalog provides high availability, by replication across several hosts. The replicas are kept consistent using a replication protocol based on the Paxos algorithm. A majority of the replicas must be available in order for the system to function. The data model used in the catalog is RDF, which allows users to create theirown name spaces and schemas. Querying is performed using SPARQL. Additionally the catalog can be used as a synchronization mechanism, by utilizing a compare and swap operation. The catalog is accessed using HTTP with proxy certificates, and uses GACL for flexible access control.The performance of the catalog is tested in several ways, including a distributed setup between geographically separated sites.
