Led by the University of Bologna, the consortium of INFINITY develops an open ecosystem of tools and infrastructures to enrich the description, reuse, and contextual understanding of Cultural Heritage Digital Objects (CHDOs). Using AI and technology, it supports ethical, multilingual, and inclusive metadata enrichment, while enabling citizen participation, ensuring IPR and provenance tracking, and providing integration with collection management systems. INFINITY contributes to the European Collaborative Cloud for Cultural Heritage (ECCCH).
