Fig. 3 — Foundational entities of DMTO in the context of BFO and OGMS. To support the interoperability and sharing capabilities of DMTO, it was designed as a sub-ontology of BFO and OGMS top-level universal ontologies. The main classes of DMTO are implemented under the most suitable upper-level universals of BFO and OGMS according to the semantics of these classes. For example, the DMTO’s drug class is implemented as a subclass of BFO’s material entity universal. The rectangles are classes, and the black lines are subclass properties
