Help:Import vocabulary

In Semantic 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.


 * A shared vocabulary can help clarify that the same word can mean a different concept or a different word (phrase) can refer to the same concept 92
 * A shared vocabulary can help the dissemination of data and avoids information to remain isolated (because of an incapability to process information when it is distributed) 92 and :392

General Concepts
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 Help: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.
