Scope note: 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. For example, a building is regarded as no longer existing if it
is dismantled and the materials reused in a different configuration. On the other hand, human beings go
through radical and profound changes during their life-span, affecting both material composition and
form, yet preserve their identity by other criteria. Similarly, inanimate objects may be subject to
exchange of parts and matter. The class E77 Persistent Item does not take any position about the nature
of the applicable identity criteria and if actual knowledge about identity of an instance of this class
exists. There may be cases, where the identity of an E77 Persistent Item is not decidable by a certain
state of knowledge.
The main classes of objects that fall outside the scope the E77 Persistent Item class are temporal
objects such as periods, events and acts, and descriptive properties.
Examples:
- Leonard da Vinci
- Stonehenge
- the hole in the ozone layer
- the First Law of Thermodynamics
- the Bermuda Triangle
