Medieval Memoria Online provides a database that is accessible free of charge, with inventories and descriptions of objects and texts that had a function in the medieval commemoration of the dead in the area that is currently the Netherlands, until 1580. These are:

• Tomb monuments and floor slabs
• Memorial pieces (Memorialbilder)
• Memorial registers (administrative and liturgical sources)
• Narrative sources that fulfilled functions in the commemoration of the dead

The database also contains basic information on the institutions in which the sources functioned. To ensure sustainable preservation of the data, the Digital Humanities Lab was tasked with upgrading the database.
