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

Which of the following definitions best describes 'E97 Monetary Amount'?

A. Scope note:
This class comprises quantities of monetary possessions or obligations in terms of their nominal value with respect to a particular currency. These quantities may be abstract accounting units, the nominal value of a heap of coins or bank notes at the time of validity of the respective currency, the nominal value of a bill of exchange or other documents expressing monetary claims or obligations. It specifically excludes amounts expressed in terms of weights of valuable items, like gold and diamonds, and quantities of other non-currency items, like goats or stocks and bonds.

Examples:
- Christie’s hammer price for Vincent van Gogh’s “Still Life: Vase with Fifteen Sunflowers” in London on 30(th) March 1987

In First Order Logic:
- E97(x) ⇒ E54(x)
B. Scope note:
This class comprises discrete, identifiable human-made items that are documented as single units. 
These items are either intellectual products or human-made physical things, and are characterized by relative stability. They may, for instance, have a solid physical form, an electronic encoding, or they may be logical concepts or structures.

Examples:
- Beethoven’s 5(th) Symphony (E73) (Lockwood, 2015)
- Michelangelo’s David (E22) (Paoletti and Bagemihl, 2015)
- Einstein’s Theory of General Relativity (E89) (Hartle, 2003)
- the taxon ‘Fringilla coelebs Linnaeus,1758’ (E55) (Sinkevicius and Narusevicius, 2002)

In First Order Logic:
- E71(x) ⇒ E70(x)
C. 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)
D. Scope note:
This class comprises those material or immaterial items to which instances of E30 Right, such as the right of ownership or use, can be applied. 
This is generally true for all instances of E18 Physical Thing. In the case of instances of E28 Conceptual Object, however, the identity of an instance of E28 Conceptual Object or the method of its use may be too ambiguous to reliably establish instances of E30 Right, as in the case of taxa and inspirations. Ownership of corporations is currently regarded as out of scope of the CIDOC CRM.

Examples:
- the Cullinan diamond (E19) (Scarratt and Shor, 2006)
- definition of the CIDOC Conceptual Reference Model Version 5.0.4 (E73) (ISO 21127: 2014)

In First Order Logic:
- E72(x) ⇒ E70(x)
