Obi-Wan is a RDF Integration System (RIS). It follows OBDA paradigm.
Features
- Uses Global-Local-As-View mappings with an simple syntax
- Supports RDFS ontologies
- Supports BGP queries (SPARQL core)
- Supports heterogeneous datasources (PostgreSQL, SQLite, MongoDB and Jena TDB)
- Provides many query answering strategies including mappings saturation
- Supports mediation-based query answering with many optimizations using Tatooine
- Supports materialization-based query answering in the triple store OntoSQL
- Uses the query rewriting algorithm of Graal
- Provides a command line interface, a SPARQL endpoint and some visualizations
