Sampo-UI allows users to navigate a Knowledge Graph using a faceted search as well as generating different types of visualisations and graphics. This software has been adapted, configured and customised to work with the EHRI-KG. If you are not an expert on semantic technologies, this is your starting point.

The SPARQL endpoint allows expert users and agents to perform arbitrary queries against the EHRI-KG triple store. It is also the backbone for the rest of the services and tools.

If you do not want to deal with SPARQL and prefer a good-old REST API, you can try our OpenAPI-compliant REST API, built using grlc.
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 v1.1 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.
