abstract: This 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.
description: The EHRI Ontology extends some of the RiC-O types and adds additional properties to represent data present in the EHRI Portal. Whenever a class is extended with new properties, a subclass bounded to the ehri prefix is created in order to maintain the original RiC-O axioms. In some cases, classes are specialised via subclassing in order to contribute additional meaning to the superclass.
