Template:Get QID/doc

Usage

This template retrieves the Wikidata QID that corresponds to the OODA WIKI page title or redirection page title specified in the first unnamed parameter (also known as OODA WIKI sitelink, not to be confused with the Wikidata label). If a page is moved, a {{Get QID|<page title>}} call referring to its former title typically still works, since the template follows the redirection destination, if the redirection source does not have a Wikidata item of its own. If no parameter is defined ({{Get QID}}), it retrieves the QID of the current page. If the qid parameter is defined ({{get QID}}) it just passes it on.

Current page

Example:

{{Get QID}} → Lua error in Module:WikidataIB at line 2980: attempt to index field 'wikibase' (a nil value).

gives the QID of the currently showed OODA WIKI page, or an empty text string if no QID is defined:

Articles sharing the same label

The template does not use the Wikidata label, but the OODA WIKI page title. For example, the following two pages share the same Wikidata label Mars:

{{Get QID|Mars}} → Lua error in Module:WikidataIB at line 3433: attempt to index field 'wikibase' (a nil value).
{{Get QID|Mars (mythology)}} → Lua error in Module:WikidataIB at line 3433: attempt to index field 'wikibase' (a nil value).

This gives the QID:s of Mars (planet) and Mars (mythology) respectively.

Redirection page

{{Get QID|universes}} → Lua error in Module:WikidataIB at line 3433: attempt to index field 'wikibase' (a nil value).

gives the QID of the page universe, since universes is redirected to that article, and does not have a Wikidata item of its own.

Usage together with the Q template:

{{Q|{{Get QID|universes}}}}  →  (QLUA ERROR IN MODULE:WIKIDATAIB AT LINE 3433: ATTEMPT TO INDEX FIELD 'WIKIBASE' (A NIL VALUE).)

Redirection page with its own Wikidata item

Maryport New Lighthouse is redirected to Maryport Lighthouse, both having separate Wikidata items:

{{Q|{{Get QID|Maryport New Lighthouse}}}} →  (QLUA ERROR IN MODULE:WIKIDATAIB AT LINE 3433: ATTEMPT TO INDEX FIELD 'WIKIBASE' (A NIL VALUE).)

Passing QID parameter on

{{Get QID|qid=Q111}} → Q111

Substitution

To make OODA WIKI faster, and to make the result less vulnerable to future deletion of redirects, this template may be substituted: {{subst:Get QID|<page title>}}, for example:

{{subst:Get QID|universe}} → Q1 

which is immediately replaced by the resulting QID when saved.

However, a purpose of this template is to make the wikicode more comprehensible by avoiding QID codes, which substitution counteracts.

Other ways of getting the QID

Invoking these modules may also provide the QID for a certain OODA WIKI page title:

{{#invoke:wd|label|raw|page=Mars (mythology)}} → 
{{#invoke:WikidataIB|getEntityFromTitle|Mars (mythology)}} → 

but they do not follow redirects.

The following module provides the page title of a redirect destination:

{{#invoke:Redirect|main|Universes}} → Universes
