Template:IntermediateNodeMapping
For extracting multiple values from a single property it is necessary to introduce an intermediate node. {{IntermediateNodeMapping}} allows to express mappings from Wikipedia template properties to ontology properties on an additional node and to connect the additional node to the mapped instance.
Usage
{{IntermediateNodeMapping
| nodeClass =
| correspondingProperty =
| mappings =
}}
Meanings
- nodeClass, correspondingProperty: Creates an additional node of the type nodeClass, which will be connected to the instance extracted from template by the property provided by correspondingProperty.
- mappings: Mappings map template properties to ontology properties, they have to be defined by using PropertyMapping, IntermediateNodeMapping, or a CustomMapping.
Example
The template property engine on the template Infobox Automobile can contain a list of engine numbers and the corresponding power and torque.
{{Infobox Automobile
| name = Volkswagen Passat
| engine = 1.6L 35 kW 135 Nm <br>
1.8L 75 PS 140 Nm
}}
The template property engine on the template Infobox Automobile is mapped to an intermediate node of the type AutomobileEngine via the ontology property engine. For this purpose we use a DBpediaIntermediateNodeMapping which defines this connection property (engine) and the mappings from values occuring in the template values of the template property engine to ontology properties on AutomobileEngine.
{{TemplateMapping
| mapToClass = Automobile
| mappings =
{{IntermediateNodeMapping | nodeClass = AutomobileEngine | correspondingProperty = engine | mappings =
{{PropertyMapping | ontologyProperty = number | templateProperty = engine }}
{{PropertyMapping | ontologyProperty = power | templateProperty = engine | unit = Power }}
{{PropertyMapping | ontologyProperty = torque | templateProperty = engine | unit = newtonMeter }}
}}
}}
