Property:Provides service
"Provides service" is a declarative predefined property to add service links to a property and is provided by Semantic MediaWiki. 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.
provides service is a special property in Semantic MediaWiki with a built-in meaning: it can be used to add service links to properties. There is no use employing this attribute on pages outside the Property namespace, it will simply be ignored.
For example, ontoworld.org uses this to display useful links for geographical coordinates.
