== Usage ==
<code><nowiki>{{</nowiki>#invoke:Is instance|''main''<nowiki>|qid=|value=}}</nowiki></code>

This module will use Wikidata properties {{Q|P31}} and {{Q|P279}} to determine whether or not an entity is an instance of some other entity.

=== Example ===
For example:
*{{Q|Q847672}}
**is an instance of {{Q|Q1185562}}, which
***is a subclass of {{Q|Q17205}}, which
****is a subclass of {{Q|Q3114762}}, which
*****is a subclass of {{Q|Q177597}}, which
******is a subclass of {{Q|Q11446}}.
To know that {{Q|Q847672}} is an instance of {{Q|Q11446}}, you can use:

<code><nowiki>{{#invoke:Is instance|main|qid=Q847672|value=Q11446}}</nowiki></code> = {{#invoke:Is instance|main|qid=Q847672|value=Q11446}}

The output number indicates the minimum recursion depth to find the value required. An output of zero indicates that the item is not an instance.

=== Maximum depth ===
For performance considerations, the module will not go on searching indefinitely. The default maximum recursion depth is 5. If you want to change this, use the {{para|maxdepth}} parameter.
