Creating a Knowledge Graph for Holocaust archival metadata
The European Holocaust Research Infrastructure (EHRI) aims to enhance access to information about Holocaust-related historical sources and promote transnational scholarship. Through the EHRI Portal it makes available over 370,000 archival descriptions, from 2,000 institutions worldwide.
EHRI-KG is an OSCARS-funded project to develop a comprehensive Linked Open Data (LOD) Knowledge Graph (KG) to complement the EHRI Portal, further advancing data accessibility and aligning with the evolving semantic web and LOD standards.

EHRI-KG outputs
These are some of the outputs generated by the EHRI-KG project.
The ontology defines the data model used by the EHRI Knowledge Graph for the representation of the information hosted in the EHRI Portal. It does so by extending RiC-O v1.0.2 and reusing some of the schema.org concepts.
The EHRI-KG Lodview interface offers an easy-to-use website to navigate over the KG entities. You will also find some example SPARQL queries that will help in answering more complex research questions.
