Components of the NPD Benchmark (v1.9.0)

• NPD Dataset (mysql dump of the original dataset, postgres and mysql schemas)

• Vig: Generates custom datasets starting from the NPD Dataset (https://github.com/ontop/vig)

• OWL 2 QL NPD ontology (containing information about petroleum activities on the Norwegian continental shelf)

• R2RML and OBDA mappings for PostgreSQL and MySQL

• 30 between Real World and Technical Queries:

  • 14 BGP Queries
  • 7 Queries with Aggregate Functions
  • 9 Queries with Tree-witnesses

• Mixer: Automatized Test Platform (https://github.com/ontop/obda-mixer) for OBDA Systems with Java OWL API interface
