General description

Name: Place
Submitted by: AldoGangemi
Also Known As:
Intent: To talk about places of things.


Competency Questions:
  • Where is a certain thing located? What is located at this place?
Solution description: This is a basic pattern, useful to represent generic locations for anything, which becomes a place when is assumed as a reference location.
Reusable OWL Building Block: (1163)
Consequences: We can represent, transitively, where something is located. It remains unspecified what kind of location relation we are trying to represent: reference location, partial location, physical location, social or metaphoric location, etc.

Moreover, temporal location is not caught with this pattern (you need a placement situation for that).

Scenarios: The Colosseum is located in Rome.

The Place Content OP locally defines the following ontology elements:

ObjectProperty hasLocation (owl:ObjectProperty) A generic, relative localization, holding between any entities. E.g. 'the cat is on the mat', 'Omar is in Samarcanda', 'the wound is close to the femural artery'.

For 'absolute' locations, see SpaceRegion

hasLocation page

ObjectProperty isLocationOf (owl:ObjectProperty) A generic, relative localization, holding between any entities. E.g. 'Rome is the seat of the Pope', 'the liver is the location of the tumor'.

As a very general notion of localization, it is assumed as transitive.

For 'absolute' locations, see SpaceRegion

isLocationOf page

Class Place (owl:Class) A location, in a very generic sense: a political geographic entity (Roma, Lesotho), a location determined by the presence of other entities ('the area close to Roma'), pivot events or signs ("the area where the helicopter fell"), complements of other entities ('the area under the table'), as well as physical objects conceptualized as locations as their main identity criterion ('the territory of Italy').

In this generic sense, a Place is an 'approximate', relative location. For an 'absolute', abstract location, cf. the pattern spaceregion.owl.

Formally, a Place is defined by the fact of having something located in it; a Place is located in itself.
