INFINITY · Multidimensional knowledge-based annotation for ethical context-aware heritage data life cycles

INFINITY advances the European Collaborative Cloud for Cultural Heritage (ECCCH) with an innovative ecosystem of tools and methods that enhance the lifecycle management of Cultural Heritage Digital Objects (CHDOs). It focuses on creating enriched, multi-context descriptions of CHDOs through multidimensional knowledge graphs, supporting their nuanced, ethical and sustainable reuse. By embedding workflows, data provenance, IPR, and diverse cultural, historical and socio-political perspectives into CHDO descriptions, the project ensures inclusive and accurate representations. Outputs adhere to FAIR principles, ensuring they are Findable, Accessible, Interoperable, and Reusable in both commercial and non-commercial contexts.Key innovations include an open library of Semantic Web and AI-driven software components for metadata enrichment, multilingual knowledge extraction and explainable AI tools, all designed for seamless integration into existing Collection Management Systems . The project introduces scalable infrastructures to support large-scale crowdsourcing and citizen science campaigns, fostering collaborative CHDO annotation and reuse. Advanced interfaces provide intuitive access to CHDO, enabling responsible interaction by diverse users, including citizens, cultural organizations, researchers and creative industries. Five use cases covering a wide range of data enrichment, IPR and ethical reuse scenarios will frame the development, validation and exploitation of INFINITY’s solutions. To drive engagement and adoption, INFINITY will establish a stakeholder network, deliver capacity-building workshops, provide training resources and launch an open call for cultural institutions and creative industries. These initiatives aim to unlock the potential of CHDOs to foster societal connections, enable innovative business models and support cultural preservation. INFINITY's innovative toolkit for CHDO metadata ensures long term success for the ECCCH.
