|E77-CIDOC - This class comprises items that have a persistent identity, sometimes known as 'endurants' in philosophy. They can be repeatedly recognized within the duration of their existence by identity criteria rather than by continuity or observation. Persistent Items can be either physical entities, such as people, animals or things, or conceptual entities such as ideas, concepts, products of the imagination or common names. The criteria that determine the identity of an item are often difficult to establish -; the decision depends largely on the judgement of the observer.
++Philosurfical: we went back to the original name in cidoc - the cipher-crm project (which is where we have initially taken the ontology specifications from) called them existence
