Reusable OWL Building Block: | http://www.ontologydesignpatterns.org/cp/owl/situation.owl (1345) |
Consequences: | This CP allows the designer to model both a certain situation, and the entities that are involved. It provides designers with a vocabulary for representing n-ary relations. |
Scenarios: | I prepared a coffee with my heater, 300 ml of water, and an Arabica coffee mix. |

Elements
The Situation Content OP locally defines the following ontology elements:
Entity (owl:Class) Anything: real, possible, or imaginary, which some modeller wants to talk about for some purpose.
For example, a PlanExecution is a context including some actions executed by agents according to certain parameters and expected tasks to be achieved from a Plan; a DiagnosedSituation is a context of observed entities that is interpreted on the basis of a Diagnosis, etc.
Situation is also able to represent reified n-ary relations, where isSettingFor is the top-level relation for all binary projections of the n-ary relation. If used in a transformation pattern for n-ary relations, the designer should take care of:
- creating only one situation for each instance of an n-ary relation, otherwise the 'identification constraint' (Calvanese et al., IJCAI 2001) could be violated
- adding an 'exact cardinality' restriction corresponding to the arity of the n-ary relation, otherwise the designer would actually represent a polymorphic relation.
Scenarios
- I prepared a coffee with my heater, 300 ml of water, and an Arabica coffee mix. >>>
