Often, when a painting is restituted, it is the conclusion of a long and arduous process of archival research to establish the itinerary of the painting and the different actors involved in its looting (or sale, or transfer, or translocation). 

What happens if we take the NAMES that appear in the provenance AFTER an artwork has left the possession of the persecuted Jewish owner and plug them in to some powerful digital tools to check other provenance texts for their presence?

Could this application of digital tools provide clues that lead to other Nazi-looted artworks?
