Their international research project “From Lima to Canton and Beyond: an AI-aided Heritage Materials Research Platform for Studying Globalisation through Art” exemplifies collaboration on a multitude of different levels: between the cultures who produced the art, between institutions researching them in present day, between collections in multiple divisions within the Library, and even between different instruments for analysis.
