Property:Imported from
From HackerspaceWiki
"Imported from" is a predefined property that describes a relation to an imported vocabulary 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.
Imported from is a special property in Semantic MediaWiki with a built-in meaning. It allows users to reuse elements of external vocabularies directly within the wiki. For more details, see the documentation at Help:Import vocabulary.
For example, ontoworld.org uses this to reuse FOAF vocabulary, such as foaf:homepage in ow:Property:homepage.
This documentation page applies to all SMW versions from 1.0 to the most current version.
