MNEME: A Collaborative Memory Platform for Cultural Heritage

MNEME is a large-scale, user-driven validation of the European Collaborative Cloud for Cultural Heritage (ECCCH). Through five pilots in Greece, Spain, Slovenia, Italy and France, the project ingests curated assets (texts, images, 3D models) and harmonises them with CIDOC-CRM/IIIF to form a federated knowledge graph that enables cross-collection discovery, comparative analysis and shared storytelling across institutions. MNEME integrates and extends core ECCCH tools—CIT for ingestion, VTL for transcription, OCRA for conservation annotation—while adding AI-assisted enrichment and condition analysis, robotic 3D capture, and AR/VR experiences that connect on-site galleries with remote audiences. Architecturally, MNEME follows a modular, microservices design with production MLOps to ensure scalable performance, reliability and reproducibility. All software is open-source and all data produced follow FAIR principles. The pilots provide end-to-end evidence—metadata completeness, link accuracy, load times and uptime, visitor engagement and training outcomes—documented as reusable protocols and recommendations contributed back to the ECCCH community and coordinated with ECHOES. By demonstrating interoperable workflows and tangible benefits for professionals, researchers and the public, MNEME turns ECCCH from infrastructure into an adoptable “collaborative memory” for Europe, ready for replication across the heritage sector.

The MNEME project has received funding from the European Union’s HORIZON-CL2-2025 under Grant Agreement No. 101285462 (Innovation Action).
