RDFIO is an RDF import and query extension for MediaWiki. It allows users to import RDF triples into MediaWiki and query the triples using SPARQL. The architecture includes an in-memory RDF store to hold the triples and a SPARQL endpoint for querying. Future plans include enhancing editing capabilities via templates and importing triples on a per-page basis. Samuel Lampa presented RDFIO and is looking for additional ideas to improve the extension.

var wikiURL = "http://drugmet.rilspace.org/wiki/";
/* Editing SMW facts */
smw.addTriple("w:Caffeine", "w:is_a", "w:Molecule", wikiURL);
smw.removeTriple("w:Caffeine", "w:is_a", "w:Molecule", wikiURL);
/* Downloading RDF for local querying */
rdfStore = rdf.createInMemoryStore();
rdfStore = smw.getRDF( wikiURL );
result = rdf.sparql( rdfStore,
"SELECT DISTINCT ?pred WHERE { ?subj ?pred ?obj } LIMIT 10"
)
/* Show some output */
js.print( result );
