Hexastore: Sextuple Indexing for Semantic Web Data Management

Summary: Hexastore uses sextuple indexing for RDF, indexing all six orderings of (s, p, o) to exploit the triple model. Each element yields two vectors of related elements and attached resources, enabling fast, scalable queries with up to five orders of magnitude speedups at the cost of up to 5× index space.
