| 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. |
| LogicalODPAuthor | Rinke Hoekstra + |
| LogicalODPComponent | http://purl.org/net/nary-relation + |
| 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. |
