Template:ObjectProperty: Difference between revisions

Revision as of 09:23, 12 March 2010

The {{ObjectProperty}} template can be used to define ontology object properties.

{{ObjectProperty
| rdfs:label   =
| rdfs:comment =
| rdfs:domain  =
| rdfs:range   =
}}

rdfs:label: should be defined to provide a human-readable version of a property's name.
rdfs:comment: should be defined to provide a human-readable description of a property.
rdfs:domain: is used to state that any resource that has a given property is an instance of the stated class. If left empty, owl:Thing is assumed.
rdfs:range: is used to state that the values of a property are instances of the stated class. If left empty, owl:Thing is assumed.

The definition of the DBpedia ontology property doctoralAdvisor:

{{ObjectProperty
| rdfs:label   = doctoral advisor
| rdfs:comment =
| rdfs:domain  = Scientist
| rdfs:range   = Person
}}
