Semantic Web

(Redirected from Semantic Web)

Although Semantic MediaWiki is designed to be used without additional technical background knowledge, it is closely related to well-known Semantic Web technologies. These technologies enable the wiki to share its knowledge with external applications by encoding it into the standard OWL/RDF format. Below is an overview of some related resources. These should be instructive for those who are familiar with semantic technologies or who wish to implement tools that use Semantic MediaWiki's RDF export. Normal users should go to the user manual to find help on using the wiki.

RDF export[edit]

The explicit semantic content of Semantic MediaWiki is formally interpreted in the OWL DL ontology language, and is made available in OWL/RDF format. For further details on the exported format, see RDF export.

Reusing vocabulary from external ontologies[edit]

Normally, all statements in the wiki refer to concepts and properties defined in the wiki, but it is also possible to directly use vocabulary from other sources. E.g. this wiki imports a number of semweb:FOAF elements for use within the wiki. A detailed description of how to use this feature is given in the article on vocabulary import.

SPARQL query service[edit]

The site can be configured to provide a SPARQL endpoint that enables expressive querying against the wiki's content. The wiki is primarily used for authoring "ABox" statements (i.e. simple facts concerning given individuals in contrast to complex schema information).

External reuse[edit]

Tools that can process OWL/RDF in a meaningful way (including many RDF tools), can also be used with Semantic MediaWiki. Archive:Reuse lists a number of applications that have been tested with the wiki's output on one site or the other.
