Reasoning in Manufacturing Part-Part Examples with OWL 2

This report examines whether the Web Ontology Language 2 (OWL 2) is expressive enough for some common manufacturing examples involving relations between parts of composite or assembled objects (part-part relations). We specify the semantics of these examples in first-order logic, express them in complex role inclusions, and compare these to OWL 2 role inclusions. We give tests based on the first order semantics and determine whether OWL 2 supports the semantics. We also give restrictions typical of part-part applications in manufacturing that might be useful in future research.
