Task: Class Definition Understanding (ontology: Arts_Media_Entertainment/CIDOC_CRM)

Which of the following definitions best describes 'E93 Presence'?

A. Scope note:
This class comprises items that have persistent characteristics of structural nature substantially related to their identity and their integrity, sometimes known as “endurants” in philosophy. Persistent Items may be physical entities, such as people, animals or things, conceptual entities such as ideas, concepts, products of the imagination or even names. 
Instances of the concept may be present or be part of interactions in different periods or events. They can repeatedly be recognized at disparate occasions during their existence by characteristics of structural nature. The respective characteristics need not be exactly the same during all the existence of an instance of the concept. Often, they undergo gradual change, still bearing some similarities with that of previous times, or disappear completely and new emerge. For instance, a person, from the time of being born on, will gradually change all its features and acquire new ones, such as a scar. Even the DNA in different body cells will develop defects and mutations. Nevertheless, relevant characteristics used should be sufficiently similar to recognize the instance for some substantial period of time. 
The more specific criteria that determine the identity of instances of subclasses of the concept may vary considerably and are described or referred to in the respective scope notes. The decision about which exact criteria to use depends on whether the observable behaviour of the respective part of reality such confined conforms to the reasoning the user is interested in. For example, a building can be 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, such as being bodily separated from other persons. Similarly, inanimate objects may be subject to exchange of parts and matter. On the opposite, the identity of a (version of a) text of a scientific publication is given by the exact arrangement of its relevant symbols. 
The main classes of objects that fall outside the scope of the the concept class are temporal objects such as periods, events and acts, and descriptive properties. 
An instance of the concept does not require actual knowledge of the identifying features of the instance being currently known. There may be cases, where the actual identifying features of an instance of the concept are not decidable at a particular state of knowledge.

Examples:
- Leonardo da Vinci (E21) (Strano, 1953)
- Stonehenge (E24) (Pryor, 2016)
- the hole in the ozone layer (E4) (Hufford and Horwitz, 2005)
- the First Law of Thermodynamics (E89) (Craig and Gislason, 2002)
- the Bermuda Triangle (E53) (Dolan, 2005)

In First Order Logic:
- E77(x) ⇒ E1(x)
B. Scope note:
This class comprises instances of E92 Spacetime Volume, whose temporal extent has been chosen in order to determine the spatial extent of a phenomenon over the chosen time-span. Respective phenomena may, for instance, be historical events or periods, but can also be the diachronic extent and existence of physical things. In other words, instances of this class fix a slice of another instance of E92 Spacetime Volume in time. 
The temporal extent of an instance of the concept typically is predetermined by the researcher so as to focus the investigation particularly on finding the spatial extent of the phenomenon by testing for its characteristic features. There are at least two basic directions such investigations might take. The investigation may wish to determine where something was during some time or it may wish to reconstruct the total passage of a phenomenon’s spacetime volume through an examination of discrete presences. Observation and measurement of features indicating the the concept or absence of a phenomenon in some space allows for the progressive approximation of spatial extents through argumentation typically based on inclusion, exclusion and various overlaps.

Examples:
- the Roman Empire on 19(th) August AD 14 (Clare and Edwards, 1992)
- Johann Joachim Winckelmann’s whereabouts in December 1775 (Leppmann, 1970)
- Johann Joachim Winckelmann’s whereabouts from 19(th) November 1755 until 9(th) April 1768 (Leppmann, 1970)

In First Order Logic:
- E93(x) ⇒ E92(x)
C. Scope note:
This class comprises people, either individually or in groups, who have the potential to perform intentional actions of kinds for which they can be held responsible.

Examples:
- London and Continental Railways (E74)
- the Governor of the Bank of England in 1975 (E21)
- Sir Ian McKellen (E21) (Gibson, 1986)

In First Order Logic:
- E39(x) ⇒ E77(x)
D. Scope note:
This class comprises sets of coherent phenomena or cultural manifestations occurring in time and space.
It is the social or physical coherence of these phenomena that identify an instance of the concept and not the associated spatiotemporal extent. This extent is only the “ground” or space in an abstract physical sense that the actual process of growth, spread and retreat has covered. Consequently, different periods can overlap and coexist in time and space, such as when a nomadic culture exists in the same area and time as a sedentary culture. This also means that overlapping land use rights, common among first nations, amounts to overlapping periods.
Often, this class is used to describe prehistoric or historic periods such as the “Neolithic the concept”, the “Ming Dynasty” or the “McCarthy Era”, but also geopolitical units and activities of settlements are regarded as special cases of the concept. However, there are no assumptions about the scale of the associated phenomena. In particular all events are seen as synthetic processes consisting of coherent phenomena. Therefore, the concept is a superclass of E5 Event. For example, a modern clinical birth, an instance of E67 Birth, can be seen as both a single event, i.e. an instance of E5 Event, and as an extended the concept, i.e. an instance of the concept, that consists of multiple physical processes and complementary activities performed by multiple instances of E39 Actor.
the concept is a subclass of E2 Temporal Entity and of E92 Spacetime Volume. The latter is intended as a phenomenal spacetime volume as defined in CIDOC CRMgeo (Doerr & Hiebel, 2013). By virtue of this multiple inheritance, it is possible to discuss the physical extent of an instance of the concept without representing each instance of it together with an instance of its associated spacetime volume. This model combines two quite different kinds of substance: an instance of the concept is a phenomenon while an instance of E92 Spacetime Volume is an aggregation of points in spacetime. However, the real spatiotemporal extent of an instance of the concept is regarded to be unique to it due to all its details and fuzziness; its identity and existence depends uniquely on the identity of the instance of the concept. Therefore, this multiple inheritance is unambiguous and effective and furthermore corresponds to the intuitions of natural language.
Typical use of this class in cultural heritage documentation is for documenting cultural and artistic periods. There are two different conceptualisations of ‘artistic style’, defined either by physical features or by historical context. For example, “Impressionism” can be viewed as a the concept in the European sphere of influence lasting from approximately 1870 to 1905 during which paintings with particular characteristics were produced by a group of artists that included (among others) Monet, Renoir, Pissarro, Sisley and Degas. Alternatively, it can be regarded as a style applicable to all paintings sharing the characteristics of the works produced by the Impressionist painters, regardless of historical context. The first interpretation is an instance of the concept, and the second defines morphological object types that fall under E55 Type.
A geopolitical unit as a specific case of an instance of the concept is the set of activities and phenomena related to the claim of power, the consequences of belonging to a jurisdictional area and an administrative system that establishes a geopolitical unit. Examples from the modern the concept are countries or administrative areas of countries such as districts whose actions and structures define activities and phenomena in the area that they intend to govern. The borders of geopolitical units are often defined in contracts or treaties although they may deviate from the actual practice. The spatiotemporal properties of Geopolitical units can be modelled through the properties inherited from E92 Spacetime Volume.
Another specific case of an instance of the concept is the actual extent of the set of activities and phenomena as evidenced by their physical traces that define a settlement, such as the populated the concept of Nineveh.

Examples:
- Jurassic (Hallam, 1975)
- Populated the concept of Nineveh
- Imperial Rome under Marcus Aurelius
- European Bronze Age (Harrison, 2004) 
- Italian Renaissance (Macdonald, 1992)
- Thirty Years War (Lee, 1991)
- Sturm und Drang (Berkoff, 2013)
- Cubism (Cox, 2000)
- The Capital of Russia (E4) [the capital of Russia in the sense of an administrative unit moved in historical times from Moscow to St Petersburg and then back to Moscow. This exemplifies an administrative unit changing place over time without temporal discontinuity]
- The settling activity of the community of Helsinki (a.k.a. Helsingfors) (E7) [the original settlement called Helsinki was located in the area of the modern airport. The community moved later to settle on the coast. This exemplifies a continued activity changing place over time without temporal discontinuity]
- Bronze Age (E4) [Bronze Age, in the sense of technological adoption, spread over disjoint areas including islands such as the British Isles without temporal discontinuity]
- Japan, the state (E4) [In 2021, the Japanese state as a political unit comprised in 6852 islands extending along the Pacific coast of Asia]
