About HeritageGraph

Preserving Cultural Heritage Through Knowledge Graphs

HeritageGraph is a platform by CAIR-Nepal for digitally preserving and publishing cultural heritage data as Linked Open Data, connecting communities, scholars, and institutions worldwide.

Our Mission

Cultural heritage is the living memory of humanity—traditions, artifacts, stories, and practices that connect us to our past and guide our future. Yet much of this heritage remains undocumented, fragmented across institutions, or at risk of being lost.

HeritageGraph aims to create a comprehensive, interconnected digital archive of cultural heritage using modern knowledge graph technologies. By publishing heritage data as Linked Open Data following CIDOC-CRM standards, we enable researchers, communities, and institutions to discover connections, share knowledge, and preserve cultural memory for future generations.
