There are hundreds of thousands of artefacts in German museums that were brought to Europe during the colonial era as a result of wars, looting or trade. The history of these objects - where they came from, what they were used for and who once owned them - is often incompletely documented. This is where an interdisciplinary research team led by the historian Prof. Dr. Dagmar Freist from the University of Oldenburg, the provenance researcher Prof. Dr. Lynn Rother (Leuphana University of Lüneburg) and the computer scientist Prof. Dr. Sascha Koch (Jade University of Applied Sciences Wilhelmshaven/Oldenburg/Elsfleth) comes in. In the "Provenance and Collection Research Digital" (ProSaDi) project, the team is compiling this knowledge together with researchers from the so-called countries of origin for two different types of collection objects. It is also developing digital techniques to make the information on the collection objects easily and widely accessible. The Lower Saxony Ministry of Science (MWK) and the Volkswagen Foundation are funding the project for four years with almost €3 million as part of the "Science Spaces" programme.
