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

Which of the following definitions best describes 'E32 Authority Document'?

A. Scope note:
This class comprises encyclopaedia, thesauri, authority lists and other documents that define terminology or conceptual systems for consistent use.

Examples:
- Webster's Dictionary (Herbert, 1994)
- Getty Art and Architecture Thesaurus (Getty Trust, 1990)
- the CIDOC Conceptual Reference Model (Gergatsoulis et al., 2010)

In First Order Logic:
- E32(x) ⇒ E31(x)
B. Scope note:
This class comprises the intellectual or conceptual aspects of recognisable marks and images.
This class does not intend to describe the idiosyncratic characteristics of an individual physical embodiment of a the concept, but the underlying prototype. For example, a mark such as the ICOM logo is generally considered to be the same logo when used on any number of publications. The size, orientation, and colour may change, but the logo remains uniquely identifiable. The same is true of images that are reproduced many times. This means that visual items are independent of their physical support.
The the concept class provides a means of identifying and linking together instances of E24 Physical Human-Made Thing that carry the same visual symbols, marks, or images, etc. The property P62 depicts (is depicted by) between E24 Physical Human-Made Thing and the depicted subjects (E1 CRM Entity) can be regarded as a shortcut of the more fully developed path from E24 Physical Human-Made Thing through P65 shows the concept (is shown by), the concept, P138 represents (has representation) to E1 CRM Entity, which in addition captures the optical features of the depiction.

Examples:
- the visual appearance of Monet’s “La Pie” (Bortolatto, 1981)
- the Coca-Cola logo (E34)
- the Chi-Rho (E37)
- the communist red star (E37)
- the surface shape of Auguste Rodin's statue "Le Penseur" [There exist more than 20 copies, even of different size. Therefore, this is a good example that it is only the common surface shape, an immaterial the concept, which justifies displaying these copies as works of Auguste Rodin. As usual practice, Rodin himself did not produce the bronze statue, but only the prototype model.]

In First Order Logic:
- E36(x) ⇒ E73(x)
C. Scope note:
This class comprises identifiable expressions in natural language or languages. 
Instances of the concept can be expressed in many ways: e.g. as written texts, recorded speech, or sign language. However, the CIDOC CRM treats instances of the concept independently from the medium or method by which they are expressed. Expressions in formal languages, such as computer code or mathematical formulae, are not treated as instances of the concept by the CIDOC CRM. These should be modelled as instances of E73 Information Object.
In general, an instance of the concept may also contain non-linguistic information, often of artistic or aesthetic value. Only in cases in which the content of an instance of the concept can completely be expressed by a series of binary-encoded symbols, its content may be documented within a respective knowledge base by the property P190 has symbolic content: E62 String. Otherwise, it should be understood as an identifiable digital resource only available independently from the respective knowledge base. 
In other cases, such as pages of an illuminated manuscript or recordings containing speech in a language supported by a writing system, the linguistic part of the content of an instance of the concept may be documented within a respective knowledge base in a note by P3 has note: E62 String. Otherwise, it may be described using the property P165 incorporates (is incorporated in): E73 Information Object as a different object with its own identity.

Examples:
- the text of the Ellesmere Chaucer manuscript (Hilmo, 2019)
- the lyrics of the song “Blue Suede Shoes” (Cooper, 2008)
- the text of the “Jabberwocky” by Lewis Carroll (Carroll, 1981)
- the text of “Doktoro Jekyll kaj Sinjoro Hyde” [an Esperanto translation of Dr. Jekyll and Mr. Hyde]. (Stevenson, Morrison and Mann, 1909)
- the free dialog in the local dialect recorded in 1958, Telemark, Norway stored on tape or.7-89.s1 (00.15:46-00:34), The Language Collection at the University Library in Bergen, Norway (verified on 2020)

In First Order Logic:
- E33(x) ⇒ E73(x)
D. Scope note:
This class comprises real persons who live or are assumed to have lived. 
Legendary figures that may have existed, such as Ulysses and King Arthur, fall into this class if the documentation refers to them as historical figures. In cases where doubt exists as to whether several persons are in fact identical, multiple instances can be created and linked to indicate their relationship. The CIDOC CRM does not propose a specific form to support reasoning about possible identity.
In a bibliographic context, a name presented following the conventions usually employed for personal names will be assumed to correspond to an actual real the concept (an instance of the concept), unless evidence is available to indicate that this is not the case. The fact that a persona may erroneously be classified as an instance of the concept does not imply that the concept comprises personae.

Examples:
- Tut-Ankh-Amun (Edwards and Boltin, 1979)
- Nelson Mandela (Brown and Hort, 2006)

In First Order Logic:
- E21(x) ⇒ E20(x)
- E21(x) ⇒ E39(x)
