bfo:specifically_dependent_continuant
Details
Annotations
- definition: b is a specifically dependent continuant =Def b is a continuant & there is some independent continuant c which is not a spatial region & which is such that b s-depends on c
- example: (with one bearer) The mass of this tomato, the pink colour of a medium rare piece of grilled filet mignon at its centre, the smell of this portion of mozzarella, the disposition of this fish to decay, the role of being a doctor, the function of this heart: to pump blood, the shape of this hole; (with multiple bearers:) John's love for Mary, the ownership relation between John and this statue, the relation of authority between John and his subordinates.
- label: specifically dependent continuant

bfo:role
Details
Annotations
- altLabel: externally-grounded realizable entity
- definition: (Elucidation) b is a role means: b is a realizable entity & b exists because there is some single bearer that is in some special physical, social, or institutional set of circumstances in which this bearer does not have to be & b is not such that, if it ceases to exist, then the physical make-up of the bearer is thereby changed
- example: The priest role, the student role, the role of subject in a clinical trial, the role of a stone in marking a property boundary, the role of a boundary to demarcate two neighbouring administrative territories, the role of a building in serving as a military target.

Details
Annotations
- altLabel: internally-grounded realizable entity
- definition: (Elucidation) b is a disposition means: b is a realizable entity & b is such that if it ceases to exist, then its bearer is physically changed, & b's realization occurs when and because this bearer is in some special physical circumstances, & this realization occurs in virtue of the bearer's physical make-up
- example: An atom of element X has the disposition to decay to an atom of element Y; the cell wall is disposed to transport cellular material through endocytosis and exocytosis; certain people have a predisposition to colon cancer; children are innately disposed to categorize objects in certain ways.
