Our Passion
MediaWiki
MediaWiki (MW) is a free, open-source software – the wiki software that powers Wikipedia and many more projects – that lets you collectively and directly edit content.
MediaWiki is a full-fledged framework, in conjunction with a lot of spin-off extensions, that can turn a website into a powerful and flexible knowledge management system for best collaboration. All information created within MediaWiki can easily be structured and published allowing users to benefit from it.
Semantic MediaWiki
Semantic MediaWiki (SMW) is a free, open-source extension to MediaWiki – the wiki software that powers Wikipedia and many more projects – that lets you store and query data within the wiki's pages.
Semantic MediaWiki is also a full-fledged framework, in conjunction with many spin-off extensions, that can further refine a wiki into a even more powerful and flexible knowledge management system. All data created within Semantic MediaWiki can easily be exported or published via the Semantic Web, allowing other software systems to use this data seamlessly.
Our Projects
Maps
Maps is the MediaWiki extension for visualizing geographical information. It is used on thousands of wikis. Jeroen developed it in 2009 using funding from Google and maintained it ever since.
Chameleon
Chameleon is a popular MediaWiki skin. It uses the Bootstrap 4 framework and is highly customizable. Stephan created it in 2013 and it is now maintained by Professional Wiki.
Semantic Bundle
Semantic Bundle is a bundle of MediaWiki extensions. It makes it easy to install Semantic MediaWiki and associated extensions in one go.
