F.38 YAMATO – Yet Another More Advanced Top-level Ontology
YAMATO is developed by Riichiro Mizoguchi, formerly at the Institute of Scientific and Industrial Research of the University of Osaka, and now at the Japan Advanced Institute of Science and Technology. Major features of YAMATO are:
- an advanced description of quality, attribute, property, and quantity,
- an ontology of representation,
- an advanced description of processes and events,
- the use of a theory of roles.
YAMATO has been extensively used for developing other, more applied, ontologies such as a medical ontology, an ontology of gene, an ontology of learning/instructional theories, an ontology of sustainability science, and an ontology of the cultural domain.
F.38.3 Key characteristics
This is a first order ontology - vide the top object called ‘Particular’. For the endurant horizontal aspect it separates occurrents and continuants - vide continuant-occurrent division of physical.

Extract 1 – Strict single inheritance
It adopts strict single inheritance in is-a hierarchy which is organized according to the rigid definition of is-a and instance-of relations based on the set membership with the notion of essential property.
Extract 2 – Genuine multiple inheritance
For the cases where genuine multiple inheritance is necessary, Hozo prepares IS-A relation which is nothing to do with identity problem of instances but only with property inheritance like subclass of relation in OWL. It may be used only when is-a relation already exists between the two types of interest.
