bITEM provides well-known museum objects with object descriptions and their biographies as well as images, related texts, 3D models as digital twins, timelines, and story maps. In addition, the objects are presented with important actors in network visualizations. OpenAtlas, a database software developed at the ACDH, is used as a backend for recording, editing, and managing data. The web application based on OpenAtlas makes it possible to explore the case studies freely accessible online. It is also possible to download data sets.
