Template:CityLocativefromCat

Template documentation[ view · edit · history · purge ]

This documentation is transcluded from Template:CityLocativefromCat/doc.

Purpose

Note that this technique does not work with all languages, because not all of them use the locative form in their "Births in" categories (pt and tr are examples of this)

Assumptions

Input

P1 expects a city's QID or its Commons category, which is generally its English name. The "Category" namespace prefix is optional.

Q270 → Warsaw (Q270)

Warsaw → Category:Warsaw → Warsaw (Q270)

Category:Warsaw → Category:Warsaw → Warsaw (Q270)

Warszawa → Category:Warszawa

Todo

• Create template that checks whether input is "Category:XXXX", "XXXX", or "Qnnnn"
  • Assume that all non-Qnnnn inputs refer to the Category?

What is more expensive? A wikidata call or mediawiki logic?
if prefix 
* ///"Category:" or "Cat:":  normalize to "Category" and continue with the complex nested calls starting with the category.
  * Category:
  
* something else: 
** Assume it is a Qnnn;
* if QID is valid
** check "instance of"
**** if category: get Category's main topic (P301)
**** if page: continue with the complex nested calls starting with the PAGE.
* if QID is invalid
** append "Category:" and try again. if it fails, return error: "P1 not a valid category"

Simpler redesign

• P373 = Commons category
• EXPECT a Commons category (in either of these formats: "Category:Warsaw" or "Warsaw", or q="Q270")
• Category: <<<
• {{wdt|Q|Category:Istanbul}}
  • {{#switch: {{#iferror: {{wdt|S.q|{{wdt|Q|{{{id|Category:{{PAGENAME:{{{1|}}}}}}}}|{{{id|Category:{{PAGENAME:{{{1|}}}}}}}}}}|P373}}}} | not | correct }}
