Using a Generic Object Model to Build an RDFS Store

Abstract – This paper presents an insert rate study for RDFS databases using secondary storage. The study explores the cost and benefits of both eager closure and truth maintenance algorithms for RDFS databases based on both OODMBS and relational technology. We review an OODBMS framework, known as the Generic Object Model, and its application to building an RDFS database and examine tradeoffs among various access path designs and their impact on an eager closure algorithm. We then measure the performance of two RDFS databases under three conditions: no closure, eager closure, and eager closure plus truth maintenance, and report on the results
