The development of a participatory archive platform such as the one being carried out for the PIA research project requires a flexible infrastructure allowing genuine data curation and a robust underlying data model. A strong assumption to achieve this is to primarily leverage Linked Open Usable Data (LOUD) standards, such as IIIF, Linked Art or the Web Annotation Data Model, which help in the dissemination and reuse of cultural heritage resources as well as contributing that digital humanities initiatives become more sustainable.
