17 Knowledge Graph for Irish History A New and Dynamic Way to Explore the Past The Knowledge Graph for Irish History is a dynamic research tool enabling discovery of information about Ireland’s deep history. The Graph uses Linked Open Data technologies to make connections between datasets and archival collections, both within and beyond the Virtual Record Treasury. The Knowledge Graph for Irish History is a Five Star Linked Open Data resource—the first of this kind to exist for Irish historical research. To date, the Knowledge Graph contains over 2.7 million linked data ‘triples’—meaningful statements—concerning people, places, offices, and organizations across Irish history. The Knowledge Graph for Irish History draws on curated datasets containing data on people, places, offices and organizations. Individual people and places mentioned in the Graph are known as ‘entities’. Every entity in the Graph has a unique resource identifier, or URI. The Knowledge Graph is a dynamic resource. As more historical entities are added, the Graph will continue to grow.
