{{Condition}}s are cases of a {{ConditionalMapping}}. They define the template property conditions and their result on the template mapping.

Usage

{{Condition
| templateProperty =
| operator         =
| value            =
| mapping          =
}}

{{Condition
| otherwise
| mapping   =
}}

Meanings

  • templateProperty: Define for which template property the condition has to apply.
  • operator: Possible values: isSet, equals, contains.
    • isSet: Condition applies if template property is set (contains any value).
    • equals: Condition applies if template property equals value.
    • contains: Condition applies if template property contains value.
  • value: If the operator value is equals or contains, define the template property value here.
  • mapping: If the condition applies, the TemplateMapping defined here are applied.
  • otherwise: otherwise is only to be used for the last condition of a ConditionalMapping. It equals the else case and defines the template mapping if none of the conditions defined before apply.

Example

A condition which maps a template to the ontology class River if the template property type equals River: 

{{Condition
| templateProperty = type
| operator         = equals
| value            = River
| mapping          = 
  {{TemplateMapping
  | mapToClass = River
  }}
}}

A condition which maps a template to the ontology class Island if the conditions defined before don't apply: 

{{Condition
| otherwise
| mapping = 
  {{TemplateMapping
  | mapToClass = Island
  }}
}}
