Attribut:Inverse

This property is the inverse of itself.

SMW doesn't automatically query the inverse of a property for you. However, you can query for the value of the inverse property on all the pages that are the objects of a property; ideally the result would match the set of pages using the property. For example,

[[Property:Location of]]

could have a query for

[[Property:Located in]]:

<ask>[[located in::<q>[[location of::+]]</q>]][[located in::*]]</ask>
