How to add an ontology class
- Find a list of existing ontology classes via the sidebar (Ontology Classes) or have a look at the class hierarchy.
- If you like to add a new ontology class, create a wiki page in the OntologyClass namespace. The page name has to be upper camel case.
- Write a Class template defining the ontology class properties like label, super class etc..
How to add an ontology property
- Find a list of existing ontology properties via the sidebar (Ontology Properties).
- If you like to add a new ontology property, create a wiki page in the OntologyProperty namespace. The page name has to be upper camel case.
- Write a DatatypeProperty template or ObjectProperty template defining the ontology property.
Ontology Schema Definition Language
The language consists of the following templates to cover the ontology schema definition:
The Class template offers the following template parameters:
- rdfs:label
- rdfs:comment
- rdfs:subClassOf
- owl:equivalentClass
The DatatypeProperty template offers the following template parameters:
- rdfs:label
- rdfs:comment
- rdfs:domain
- rdfs:range
- owl:equivalentProperty
The ObjectProperty template offers the following template parameters:
- rdfs:label
- rdfs:comment
- rdfs:domain
- rdfs:range
- owl:equivalentProperty
Examples
The definition of the DBpedia ontology class Person (using the Class template):
{{Class
| rdfs:label = Person
}}
The definition of the DBpedia ontology property height (using the DatatypeProperty template):
{{DatatypeProperty
| rdfs:label = height
| rdfs:domain = Person
| rdfs:range = centimeter
}}
The definition of the DBpedia ontology property doctoralAdvisor (using the ObjectProperty template):
{{ObjectProperty
| rdfs:label = doctoral advisor
| rdfs:domain = Scientist
| rdfs:range = Person
}}
