/**
 * DokuSIOC - SIOC plugin for DokuWiki
 *
 * DokuSIOC integrates the SIOC ontology within DokuWiki and provides an
 * alternate RDF/XML views of the wiki documents.
 *
 * For DokuWiki we can't use the Triplify script because DokuWiki has not a RDBS
 * backend. But the wiki API provides enough methods to get the data out, so
 * DokuSIOC as a plugin uses the export hook to provide accessible data as
 * RDF/XML, using the SIOC ontology as vocabulary.
