Overview / Open Energy Ontology / Class - generically dependent continuant

Label: generically dependent continuant

Definition:

b is a generically dependent continuant = Def. b is a continuant that g-depends_on one or more other entities. (axiom label in BFO2 Reference: [074-001])

Sub classes:

information content entity

view

Definition:

A generically dependent continuant that is about some thing.

Editor note:

2014-03-10: The use of "thing" is intended to be general enough to include universals and configurations (see https://groups.google.com/d/msg/information-ontology/GBxvYZCk1oc/-L6B5fSBBTQJ).

An information content entity is a non-realizable information entity that 'is encoded in' some digital or physical entity.

model component

view

Definition:

A model component is a generically dependent continuant that is part of a model.

model system boundary

view

Definition:

A model system boundary is a generically dependent continuant that is part of a model and separates aspects of the real world included in the model from those that are not.

sector

view

Definition:

A sector is generically dependent continuant that is a subdivision of a system.

sector division

view

Definition:

A sector division is a specific way to subdivide a system.

technical model implementation

view

Definition:

A technical model implementation is a generically dependent continuant that is part of a model and consists of the hardware and software realization of a (conceptual) model.

unit

view

Definition:

A unit of measurement is a generically dependent continuant that represents a standardised quantity value of a quantifiable entity

Editor note:

The OEO developers have different views on the correct classification of a (physical) unit. On one hand, a (physical) unit is often referred to be "a standardized quantity", e.g. in the UO, and thus is interpreted as a quantity itself. On the other hand, a (physical) unit can be seen as a generically dependent reference measure that is not bound to a specific bearer. Together with the numerical value it can describe a quantity value. In the OEO, we have opted for the latter view and therefore implemented (physical) unit as generically dependent continuants.

Back to the super classes:

continuant

view

Definition:

An entity that exists in full at any time in which it exists at all, persists through time while maintaining its identity and has no temporal parts.

Editor note:

BFO 2 Reference: Continuant entities are entities which can be sliced to yield parts only along the spatial dimension, yielding for example the parts of your table which we call its legs, its top, its nails. ‘My desk stretches from the window to the door. It has spatial parts, and can be sliced (in space) in two. With respect to time, however, a thing is a continuant.’ [60, p. 240

Editor note:

Continuant doesn't have a closure axiom because the subclasses don't necessarily exhaust all possibilites. For example, in an expansion involving bringing in some of Ceuster's other portions of reality, questions are raised as to whether universals are continuants
