Proprietà:External formatter uri (External formatter URI)
"External formatter uri (External formatter URI)" è una proprietà predefinita fornita da Semantic MediaWiki per specificare una risorsa esterna con un segnaposto. 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.
