'''OntoWiki''' was a free and open-source semantic wiki application, meant to serve as an ontology editor and a knowledge acquisition system. It is a web-based application written in PHP and using either a MySQL database or a Virtuoso triple store. OntoWiki is form-based rather than syntax-based, and thus tries to hide as much of the complexity of knowledge representation formalisms from users as possible. OntoWiki is mainly being developed by the [http://aksw.org Agile Knowledge Engineering and Semantic Web (AKSW) research group] at the University of Leipzig, a group also known for the DBpedia project among others, in collaboration with volunteers around the world.
In 2009 the AKSW research group got a budget of €425,000 from the Federal Ministry of Education and Research of Germany for the development of the OntoWiki.<ref>[http://idw-online.de/pages/de/news300375 "OntoWiki" hilft Daten im Web zu verknüpfen] (German)</ref>
In 2010 OntoWiki became part of the technology stack supporting the LOD2 (linked open data) project. Leipzig University is one of the consortium members of the project, which is funded by a €6.5m EU grant.<ref>{{cite web |url=http://cordis.europa.eu/fetch?CALLER=PROJ_ICT&ACTION=D&CAT=PROJ&RCN=95562 |publisher=European Commission |title=CORDIS FP7 ICT Projects - LOD2 |date=2010-04-20}}</ref>
The development ended in 2016 due to the lack of capacity migrating from PHP 5 to 7 including the required Zend Framework from version 1 to 2.<ref>{{cite web |url=https://github.com/AKSW/OntoWiki/issues/441#issuecomment-815587074 |publisher=Natanael Arndt aka white-gecko |title=Comment to "How and why did this end? |date=2021-04-08 }}</ref>
