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: 

{{Class 
| rdfs:label  = Person
}}

The definition of the DBpedia ontology property height: 

{{DatatypeProperty 
| rdfs:label  = height
| rdfs:domain = Person
| rdfs:range  = centimeter
}}
