General idea  Extending Stolpersteine to a higher level and use it as a starting point.  Developing an app, called Stolperwege, for ubiqui- tous modeling of historical processes.  Modelling biographies of victims of Nazism and inte- grate diferent data sources (public, archive).  Modelling historical environments to create diferent views of the past: – Synchronizes present-day maps with their histori- cal counterparts. – Interactive 3D animations of destroyed or not ac- cessible buildings. Stolperwege App  Multiple view on biographies. Specific: – Present-day and historical maps – Interactive 3D / VR animations  Distributed components for flexible and redundant use.  Resource management and data protection with the ResourceManager (Gleim, Mehler, and Ernst 2012) and the AuthorityManager.  Used free libraries only, e.g. OpenStreetMap  RESTful backend to communicate with the App.  Database model based on UIMA type system.

Outlook  Future work aims at instantiating Stolperwege by means of biographical information about persons for which Stolpersteine exist in Frankfurt am Main and to make it open source.  Extend the functions for virtual and augmented-reality requirements.
