Module:Cite Q

Usage

A wrapper for {{Citation}}, which calls available values from Wikidata.

An example of an article using this template for all of its references is en:South Pole Telescope; an example using Harvard style citations is en:Suffix automaton.

By default, if there are more than eight author names, the template displays three, followed by "et al". This can be changed using |display-authors=; using that parameter with no value displays them all. The same applies to multiple editors - see the test-case pages.

Future developments

• Once robust the functionality should be merged into {{Citation}}
• Eventually, each signed-in reader should be able to set, under their "Preferences", the style in which they wish to see citations rendered.
• We should have a [[:mediawiki:|Global templates|lobal template repository]], so the code can be used by multiple wikis, without having to manually copy it after every update.g

Parameters

• |1= = Wikidata QID for the article

Additionally, any named parameter used in {{Citation}} may be entered and will overwrite the value in Wikidata. Using such parameters, with a value of unset, will suppress display of data from Wikidata.

Blank

<ref name="">{{Cite Q| XXQIDXX }}</ref>

Reference naming

For ease of use, you may wish to name your references to reflect the cited work, for example:

<ref name="Williams-2010">{{Cite Q|Q15625490}}</ref>
