SMW+

SMW+ was an open-source software bundle composed of the wiki application MediaWiki along with a number of its extensions, that was developed by the German software company Ontoprise GmbH from 2007 to 2012. In 2012, Ontoprise GmbH filed for bankruptcy and went out of business. DIQA-Projektmanagement GmbH, a start-up founded by former Ontoprise employees, now offers support for the software in SMW+, though under the name "DataWiki."

Details
SMW+'s extensions include, most notably, Semantic MediaWiki and the Halo Extension. Cumulatively, SMW+ functions as a semantic wiki and is also meant to serve as an enterprise wiki for use within companies, for applications such as knowledge management and project management.

The SMW+ platform was available in a number of formats including a Windows installer, Linux installer, and VMware image.

SMW+ emerged from Project Halo, a research project meant to provide a platform for collaborative knowledge engineering for domain experts in biology, chemistry, and physics at the first stage.
