Download Now Free registration required

Executive Summary

RDF is a data representation format for schema-free structured information that is gaining momentum in the context of Semantic-Web corpora, life sciences, and also Web 2.0 platforms. The "Pay-as-you-go" nature of RDF and the flexible pattern-matching capabilities of its query language SPARQL entail efficiency and scalability challenges for complex queries including long join paths. This paper presents the RDF-3X engine, an implementation of SPARQL that achieves excellent performance by pursuing RISC-style architecture with a streamlined architecture and carefully designed puristic data structures and operations.
