A number of approaches have been developed for combining wikis with semantic technologies. Many semantic wikis focus on enabling users to specify properties and relationships of individual elements. Complex schema information is typically not edited by the wiki user. Nevertheless, semantic wikis could benefit from taking existing schema information into account, and to allow users to specify additional information based on this schema. In this paper, we introduce an extension of Semantic MediaWiki that incorporates schema information from existing OWL ontologies. Based on the imported ontology, the system offers automatic classification of articles and aims at supporting the user in editing the wiki knowledge base in a logically consistent manner. We present our prototype implementation which uses the KAON2 ontology management system to integrate reasoning services into our wiki.
