IMPORTANT ADVICE: To get you started with SMW⁺, we included a set of lessons into this Wiki that features step-by-step instructions about how to do basic wiki administration and how to create articles and data. We strongly recommend that you carefully follow the lessons.

SMW⁺ is a semantic enterprise wiki that is distributed by Ontoprise GmbH, Karlsruhe, Germany. This tool is well suited for organizations or teams dealing with heterogeneous and informal workflows and offers a rich feature set to create, share, publish and re-use knowledge contained in content. Ontoprise develops extensions to MediaWiki and carefully picks other useful extensions and, if having passed our quality assurance procedure, casts them into SMW⁺.

SMW⁺ includes Semantic MediaWiki (developed by Markus Krötzsch and Denny Vrandecic at the university of Karlsruhe) and the halo-Extension which is developed by Ontoprise in the HALO project, a Paul G. Allen initiative which is sponsored by his Seattle-based Vulcan Inc.
