Category:Special property

Certain special properties are built-in to Semantic MediaWiki to make the system work. They appear in a page's Factbox in italic. Since SMW 1.4.0, special properties can be used in browsing interfaces and inline queries just like all other properties. Also see the Properties and types help page for more information.

The names and aliases of special properties are reserved and cannot be used for other properties. Special properties should only be used according to their documented purpose!

The pages listed below on www.semantic-mediawiki.org provide documentation for Semantic MediaWiki's special properties, but are not required; a special property will have special behaviour even if your wiki does not have a property page for it.

In an extension, you can create your own special properties using the smwInitProperties hook. See, for example, the usage in SemanticACL.
