Module:Is instance/doc

Usage

{{#invoke:Is instance|main|qid=|value=}}

This module will use Wikidata properties instance of (P31) and subclass of (P279) to determine whether or not an entity is an instance of some other entity.

For example HMS Ark Royal (Q847672) is an instance of light aircraft carrier (Q1185562), which is a subclass of aircraft carrier (Q17205), which is a subclass of warship (Q3114762), which is a subclass of naval vessel (Q177597), which is a subclass of ship (Q11446). To know that HMS Ark Royal (Q847672) is an instance of ship (Q11446), you can use:

{{#invoke:Is instance|main|qid=Q847672|value=Q11446}} = 3

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.
