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.

Example

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.

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 |maxdepth= parameter.
