Graphical representation



General description

Name: constituency
Submitted by: ValentinaPresutti
Also Known As:
Intent: To represent the constituents of a layered structure.

Parts and Collections

Competency Questions:
  • Which are the constituents of this entity?
  • What does this entity is constituent of?
Solution description: -
Reusable OWL Building Block: (860)
Consequences: A desirable advantage of this CP is that we are able to talk e.g. of physical constituents of

non-physical objects (e.g. systems), while this is typically impossible in terms of parts. This Content OP has to be distinguished from part of, collection entity, and componency Content OPs.

Scenarios: Different types of wood constitute this table.

The Constituency Content OP locally defines the following ontology elements:

Class Entity (owl:Class) Anything: real, possible, or imaginary, which some modeller wants to talk about for some purpose.

Entity page

ObjectProperty hasConstituent (owl:ObjectProperty) Constituency depends on some layering of the world described by the ontology. For example, scientific granularity (e.g. body-organ-tissue-cell) or ontological 'strata' (e.g. social-mental-biological-physical) are typical layerings. Intuitively, a constituent is a part belonging to a lower layer. Since layering is actually a partition of the world described by the ontology, constituents are not properly classified as parts, although this kindship can be intuitive for common sense. Example of constituents include the wood pieces constituting a table, the persons constituting a social system, the molecules constituting a person, the atoms constituting a river, etc. In all these examples, we notice a typical discontinuity between the constituted and the constituent object: e.g. a table is conceptualized at a functional layer, while wood pieces are conceptualized at a material layer, a social system is conceptualized at a different layer from the persons that constitute it, a person is conceptualized at a different layer from the molecules that constitute them, and a river is conceptualized at a different layer from the atoms that constitute it. The object property isConstituentOf is its inverse.
