Type:URL

From OWL

Properties of type URL (or URI) are exported as object properties that relate to the given URI. For this reason, this type does not admit URIs from the OWL or RDF namespaces: they would make the output invalid for OWL DL. If you need to use such URIs as values, consider encoding them as plain strings. For more information, see the Semantic MediaWiki documentation.

This type is among the standard datatypes of this wiki.
