Template:ConditionalMapping
{{ConditionalMapping}} maps templates to ontology classes. In comparison to a TemplateMapping the mapping can be defined depending on template properties and their values.
Usage
{{ConditionalMapping
| cases =
| defaultMappings =
}}
Meanings
- cases: Cases define conditions on template properties and their values and can change the default mapping, like the ontology class the template is mapped to and the ontology properties the template properties are mapped to. The cases template property should contain a list of Condition templates.
- defaultMappings: The default mapping defines the default template property mappings using PropertyMapping etc.. The default ontology class the template is mapped to has to be defined by an otherwise condition.
Example
{{ConditionalMapping
| cases =
{{Condition
...
}}
...
{{Condition
| operator = otherwise
...
}}
| defaultMappings =
{{PropertyMapping
...
}}
...
}}
Example of Mapping Gender
On bg.wikipedia.org, females have a field наставка="а". "наставка" means suffix, and you may know that many Bulgarian and Russian female surnames end in "a". Weirdly but consistently, the same value is used for foreign female names like София Лорен. So if the field is present it's a Female, otherwise it's a Male.
Since the mapping wiki has infobox mappings but not property mappings, we have to do the same for all infoboxes using наставка (currently 9). Lets's do it for the mapping of President, Mapping_bg:Президент_инфо. Since templates must be nested like this:
ConditionalMapping
Condition
TemplateMapping
ConstantMapping
we end up repeating mapToClass=OfficeHolder twice, whereas defaultMappings includes all common property mappings:
{{ ConditionalMapping | cases =
{{ Condition
| templateProperty = наставка
| operator = isSet
| mapping = {{ TemplateMapping | mapToClass = OfficeHolder | mappings =
{{ConstantMapping | ontologyProperty = gender | value = http://dbpedia.org/resource/Female}}}}}}
{{ Condition
| operator = otherwise
| mapping = {{ TemplateMapping | mapToClass = OfficeHolder | mappings =
{{ConstantMapping | ontologyProperty = gender | value = http://dbpedia.org/resource/Male}}}}}}
| defaultMappings =
{{ PropertyMapping | templateProperty = име | ontologyProperty = foaf:name }}
{{ PropertyMapping | templateProperty = роден-дата | ontologyProperty = birthDate }}
...
}}
We can test the extraction on two presidents:
- Barack Obama, male
- Dilma Rousseff, female. (She is of Bulgarian descent but she has lost her suffix "a" because she never lived in Bulgaria)
