General description

Name:	Place
Submitted by:	AldoGangemi
Also Known As:
Intent:	To talk about places of things.
Domains:	General
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:	1 (732)
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.

Elements

The Place Content OP locally defines the following ontology elements:

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

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

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').
