Comparison
Specific Representation permits the customization of the database representation of RDF metadata
Specific Representation outperforms the Generic Representation for all types of queries
- Q1, Q2, Q5, Q7, Q10, Q11: by a factor up to 3.73
- Q3, Q4, Q6: by a factor up to 2.8
- Q8, Q9: by a factor up to 95,538
Generic representation pays severe penalty for maintaining large tables (Triples, Resources)
- e.g., queries Q8, Q9 require (self-) joins of Triples, Resources
