Semantic mediawiki
From eg
The semantic mediawiki (.org) extension supports RDD statements and creates 'meta' pages that are a "view" of queries against the wiki-as-a-database - making a semantic wiki.
It does NOT regulate use of any ontology and is widely used to support many industry- and field-specific ontologies. See the real web 3.0 for a good explanation of why it's useful.
The semantic mediawiki portal and a more general semantic wiki portal at ontoworld.org provide details on the project, its assumptions and direction(s).
[edit] How it works
Adding special wikitext to data makes it generate RDF statements which can then be further augmented, adding ontologies.
One can categorize links to create formal relations between pages, or create typed links. For instance:
- ... [[capital of::Germany]] ... on the page "Berlin"
creates the semantic statement "Berlin" "capital of" "Germany". Or, on the same page
- ... the population is [[population:=3,993,933]] ...
creates the semantic statement "Berlin" "has population" "3993933"."
[edit] Similar projects
This is semantic web unpolluted with ontologies and rigid formalisms, which are NOT inherent in the semantic web model, more consistent with Tim Berners-Lee's original conception of the W3C model.
The dbpedia project is another similar project described in a post by Tim O'Reilly. The freebase.com project also has similar capabilities.
The living ontology patterns affect wiki page names, some of which are stylized to be understood or intepreted as specific verb/noun/type combinations, especially via the use of prepositions. It is easy to convert these to semantic mediawiki links.
