=== Common use cases ===
Below follows a list of common use cases. In the future, shortcut commands may be implemented that are equivalent to these calls for convenience.
{| class="wikitable"

! Call
! Use case
|-
| {{nowrap|{{tnull|{{{prename|}}}{{lcfirst:{{ROOTPAGENAME}}}}|label|raw|{{{extraparams|}}}}}}}
| Returns the Q-identifier of the Wikidata item connected to the current page (e.g. "Q55").
|-
| {{nowrap|<code><nowiki>{{#if:</nowiki>{{tnull|{{{prename|}}}{{lcfirst:{{ROOTPAGENAME}}}}|label|raw|{{{extraparams|}}}}}<nowiki>|...}}</nowiki></code>}}
| Performs a check to determine if the current page has a Wikidata item.
Note that this statement relies on a returned value that is either empty or non-empty and that the <code>raw</code> flag is important to include. Without this flag, an existing item's regular label would be returned which could be empty, giving an undesired result. If the flag is given on the other hand, then a non-empty Q-identifier is always returned if an item exists and an empty value if an item does not exist.
