<p><b>New page</b></p><div>'''Subproperty of''' is a [[special property]] in [[Semantic MediaWiki]] with a built-in meaning: it lets you indicate that one property is a subproperty of another.<br />
<br />
It means that a [[Help:Semantic search|query]] for pages with the property should also return pages that have the subproperty. For example, querying for the property "spouse" should also find pages with the properties "wife" and "husband", if those properties have the special property ''<nowiki>[[subproperty of::Property:spouse]]</nowiki>''<br />
<br />
This also agrees with [http://www.w3.org/TR/rdf-schema/#ch_properties rdfs:subPropertyOf]:<br />
: If property P is a subproperty of property P', then all pairs of resources which are related by P are also related by P'. <br />
<br />
== Notes ==<br />
<br />
* A property's page shows its subproperties since [[SMW 1.2.1]].<br />
* If no pages (or very few pages) in the wiki use a property, then even if lots of pages use its subproperties:<br />
** The property's page will list no (or few) pages under "Pages using the property"<br />
** The property won't appear in [[Special:Properties]] (or will appear with a caution <small>This property is hardly used within the wiki!</small>).<br />
