Does Timbr integrate an inference engine, and does it work similarly to the inference found in OWL ontologies?

Yes. Timbr fully complies with OWL DL and its SQL re-write engine functions as an inference engine, automatically generating queries based on inference rules including inheritance, transitivity, and others. Inference can be defined through Timbr’s visual interface or via SQL statements. Timbr also goes beyond OWL by enabling business logic through SQL and expressing aggregations as ontology concepts – capabilities not available in standard OWL.
