Thanks for your interest in my work. On this page I want to describe in detail some of the projects I worked in. You can find all my publications and scientific work at ORCID: 0000-0003-3417-9486, my Wikidata ID is Q100466271. Here are some of my projects:

  • Semantic CorA – a virtual research environment based on Semantic Media Wiki. Basically the basis of most of the projects
  • QualiCO – an ontology for qualitative coding schemas. I created this ontology during my PhD. The ontology helps to make qualitative research more transparent and can be seen as the start of a research knowledge graph in qualitative research. You can find more details and publications on Github.
  • Interlinking Pictura – a citizen science project with the amazing pictures of the “Bilderbuch für Kinder” by Friedrich Justin Bertuch from the beginning of the nineteenth century.
  • Schularchive – a wiki where researchers and school archivists can share the location of historical sources in schools. We modelled the structure of schools and sources about schools as a graph-based structure. I also developed two extensions to support this wiki: WikidataShow to reuse data from Wikidata and GNDShow to reuse data from the German National Library. With this project I was awarded fellow for free knowledge funded by Wikimedia Germany.
  • VRE Objective Hermeneutics – a virtual research environment for the method objective hermeneutics. You can find the MediaWiki extension on Github.
  • Open Data for educational research – In this project we analyzed the quality of governmental open data portals. The focus was on the potentials of this data for educational research. You can find a summary of the paper in my blog.


  • WikidataShow: an extension for MediaWiki that shows information from Wikidata in MediaWiki pages. We use it at the project Schularchive to display pictures and links to other projects like Wikipedia
  • GNDShow: an extension for MediaWiki that shows information from the German National library.
