Cultural Heritage Research Digital is dedicated to sustainable research, comprehensive accessibility and the sustainable and long-term preservation of material cultural heritage. In this context, digital technologies open up new possibilities for transdisciplinary material-related research, data-related networking and science communication-related experiments in the hybrid intersection of analogue and digital methods and formats. Digital cultural heritage research (eCultural Heritage) at Carl von Ossietzky University has an international focus and specialises in antiquity and early modern/modern history (ca. 1500-1918). The research topics are embedded in global historical contexts in antiquity and in the era of European expansion, colonialism and postcolonial studies as well as the globalisation of (pre-)modernity. The digital methods and digital tools are developed transdisciplinarily on the subject matter and in relation to the epistemological questions. This involves working with national research data infrastructures and supporting the establishment of a Lower Saxony cultural heritage research data infrastructure in co-operation with the VZG/GBV Göttingen. Almost all projects work closely with the Data Science, Geoinformatics and Photogrammetry (historical materiality research) departments at Jade University. There are also international co-operations for the further development of digital tools and the interoperability of databases. Further joint projects are currently being applied for. A unifying feature is the co-operation with archives, museums and relevant research networks, including the German Maritime Museum Bremerhaven / Leibniz Research Institute for Maritime History, the State Museum of Nature and Man Oldenburg, the State Museum Hanover and the Lower Saxony Provenance Research Network, as well as a wide range of international co-operations.
