Property:External formatter URI

The property namespace is disabled, attempting to declare a type or other property specific characteristics for this property is not possible.

"External formatter URI" is a predefined property provided by Semantic MediaWiki to specify an external resource with a placeholder. The URI is expected to contain a placeholder that will be adjusted with an external identifier value to form a valid resource reference. This property is pre-deployed (also known as special property) and comes with additional administrative privileges but can be used just like any other user-defined property.
