<noinclude>'''<nowiki>{{Condition}}</nowiki>'''s are cases of a [[Template:ConditionalMapping|ConditionalMapping]]. They define the template property conditions and their result on the template mapping.
=== Usage ===
<pre>
{{Condition

}}
</pre>

=== Meanings ===
* '''templateProperty''': Define for which template property the condition has to apply.
* '''operator''': Possible values: ''isSet'', ''equals'', ''contains'', ''otherwise''.
** ''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''.
** ''otherwise'': 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.
* '''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.
=== Example ===
A condition which maps a template to the ontology class ''River'' if the template property ''type'' equals ''River'':
<pre>
{{Condition
| templateProperty = type
| operator        = equals
| value            = River
| mapping          =
  {{TemplateMapping
  | mapToClass = River
  }}
}}
</pre>
A condition which maps a template to the ontology class ''Island'' if the conditions defined before don't apply:
<pre>
{{Condition
| operator = otherwise
| mapping =
  {{TemplateMapping
  | mapToClass = Island
  }}
}}

{{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
| operator = otherwise
| mapping  =
}}

Meanings

  • templateProperty: Define for which template property the condition has to apply.
  • operator: Possible values: isSet, equals, contains, otherwise.
    • 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.
    • otherwise: 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.
  • 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.

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