The definition of the DBpedia ontology class Person (using the Class template):

| rdfs:label  = Person
}}

The definition of the DBpedia ontology property height (using the DatatypeProperty template):

| rdfs:domain = Person
| rdfs:range  = centimeter
}}

The definition of the DBpedia ontology property doctoralAdvisor (using the ObjectProperty template):

{{ObjectProperty
