InSemantic MediaWiki it is possible to import and reuse vocabulary that belongs to existing Semantic Web documents or standards by associating the vocabulary's elements with wiki terms.
Normally, concepts that can be described (and be used for description) in the wiki are defined by the wiki and thus are local. So the URI that RDF export uses to denote a concept is usually from a specific namespace that should be used only by the wiki. Even if you create a property that seems to come from a well-known vocabulary because you name it foaf:knows, it would still be exported with the URI
http://''your.site''/wiki/Special:URIResolver/Property-3AFoaf-3Aknows
which is the XML-compatible URI derived from the article URL (see RDF export for details). Semantic MediaWiki's mechanism for importing vocabularies solves this problem by allowing the reuse of external vocabulary in a controlled way.
Because of this mechanism, it is not required to change the names of your local properties. You can name the properties in your wiki the way you want and still reuse any vocabulary at any later point in time. "Importing" vocabulary simply will result in a change in the RDF representation.
The following list of examples contains vocabularies that may or may not be completed. The vocabularies in bold are being imported automatically when SMW is installed.
