The Has query property is a special property in Semantic MediaWiki with a built-in meaning: it links a page to the subobject of a query which records it's profile. This subobject holds information about the respective query which itself may be queried. This information includes the depth, the format, the size and the string of the respective query. Starting with with Semantic MediaWiki 1.9.0 the duration1 was added and Semantic MediaWiki 2.5.0 brought information about it's parameters2.

This special property should never be set manually, since Semantic MediaWiki will take care of setting its value dynamically. Starting with Semantic MediaWiki 2.2.0 it is no longer possible to manually add values for this special property.3
