The document discusses the integration and management of archaeological datasets through the Europeana projects CARARE and 3D-ICONS, highlighting the need for infrastructures that preserve and make research data accessible. Europeana acts as a digital library hosting over 25 million objects, and the CARARE project aims to enhance the representation of archaeology and architectural heritage within this platform. The ongoing 3D-ICONS project further extends this effort by focusing on 'masterpieces' of European heritage, making digital content widely available for public engagement and research.
