Submissions:N-Ary Relation Pattern (OWL 2)
GraphicallyRepresentedBy Nary-relation.png +
LogicalODPAim The aim of this pattern is to allow the inference of property relations between the different relata of the original N-Ary relation based on its reification.

LogicalODPComponent  +
LogicalODPComponentDescription OWL 2 RDF/XML
LogicalODPConsequence The patient (Christine, P) is related both to the diagnosis value (Cancer) and its probability.
LogicalODPDescription The N-Ary relation is reified by creating The N-Ary relation is reified by creating a class for the relation (NR), and creating properties and classes for the domain (D) and ranges (R1-Rn) of the relation (that is, if the relation is directional). The NR class is specified using a local reflexivity restriction of the form: NR equiv is_NR some Self. We then specify role chains for each of the binary relations between the domain and ranges. For instance: has_NR o is_NR o r1 -> has_r1 instance: has_NR o is_NR o r1 -> has_r1
LogicalODPElements OWL 2 local reflexivity and property chains.
LogicalODPMotivation OWL does not support N-Ary relations. This means that an n-ary relation can only be represented in its reified form in OWL. This is problematic, as the relational character is then completely lost.
LogicalODPName N-Ary Relation Pattern (OWL 2)  +
LogicalODPScenario See the picture, where the cancer diagnosis relation of the SWBP N-Ary relations patterns is expressed using this design pattern.
LogicalODPWorkflow Alter the axioms in the reusable component to suit your needs. The component contains an N-Ary relation with four ranges and a domain. This can easily be extended or reduced.
