The special collection showcases 400 photographs, capturing the essence of art and architecture in Argentina from early modern times to the present day. These photographs were taken by Tristan Weddigen during a 2016 field trip that focused on the neocolonial modernism spearheaded by the architect Ángel Guido. Nicole Falconi Müller meticulously collected the metadata for the 230 objects, which have been organized, defined, and linked according to the latest standards. We utilized the CIDOC-CRM ontology, a product of the Swiss Art Research Infrastructure (SARI), within the EasyDB digital asset management system. This approach ensures that the open-linked data is locatable, accessible, interoperable, and reusable (FAIR). While the photographic collection does not provide a comprehensive view of Argentinian cultural heritage, it aims to support research and warmly welcomes external contributions.
