OGMS Big Picture

From BFO to OGMS

• Material Entity• Disposition• Process

• Disorder• Disease• Disease Course

BFO

Top-level terms in the OGMS ontology

• Disorder = part of an organism which deviates from the normal (a necrotic liver …)

• Disease = a disposition to bad things which exists in virtue of one or more disorders

• Disease course = the realization (manifestation) of such a disposition

IHI• using BFO, OGMS and their extension ontologies

to provide a consistent framework for the representation of the types of particulars

• developing systematic ways for the consistent tracking of particulars (patients, disorders, encounters …)

• putting these together to serve consistent representation of the assertional knowledge in the IHI repository
