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

Which of the following definitions best describes 'E90 Symbolic Object'?

A. Scope note:
This class comprises all persistent physical items with a relatively stable form, human-made or natural.
Depending on the existence of natural boundaries of such things, the CIDOC CRM distinguishes the instances of E19 Physical Object from instances of E26 Physical Feature, such as holes, rivers, pieces of land, etc. Most instances of E19 Physical Object can be moved (if not too heavy), whereas features are integral to the surrounding matter.
An instance of the concept occupies not only a particular geometric space at any instant of its existence, but in the course of its existence it also forms a trajectory through spacetime, which occupies a real, that is phenomenal, volume in spacetime. We include in the occupied space the space filled by the matter of the the concept and all its inner spaces, such as the interior of a box. For the purpose of more detailed descriptions of the presence of an instance of the concept in space and time it can be associated with its specific instance of E92 Spacetime Volume by the property P196 defines (is defined by). 
The CIDOC CRM is generally not concerned with amounts of matter in fluid or gaseous states, as long as they are not confined in an identifiable way for an identifiable minimal time-span.

Examples:
- the Cullinan Diamond (E19) (Scarratt and Shor, 2006)
- the cave “Ideon Andron” in Crete (E26) (Smith, 1844-49)
- the Mona Lisa (E22) (Mohen, 2006)

In First Order Logic:
- E18(x) ⇒ E72(x)
B. Scope note:
This class comprises immaterial items, including but not limited to stories, plots, procedural prescriptions, algorithms, laws of physics or images that are, or represent in some sense, sets of propositions about real or imaginary things and that are documented as single units or serve as topic of discourse. 
This class also comprises items that are “about” something in the sense of a subject. In the wider sense, this class includes expressions of psychological value such as non-figural art and musical themes. However, conceptual items such as types and classes are not instances of the concept. This should not be confused with the definition of a type, which is indeed an instance of the concept.

Examples:
- Maxwell’s Equations (Ball, 1962)
- the ideational contents of Aristotle’s book entitled ‘Metaphysics’ as rendered in the Greek texts translated in Oxford edition
- the underlying prototype of any “no-smoking” sign (E36)
- the common ideas of the plots of the movie “The Seven Samurai” by Akira Kurosawa and the movie “The Magnificent Seven” by John Sturges (Mellen, 2002)
- the image content of the photo of the Allied Leaders at Yalta published by UPI, 1945 (E36)
- the character “Little Red Riding Hood”, variants of which appear amongst others in Grimm brothers’ “Rotkäppchen”, other oral fairy tales and the film “Hoodwinked”
- the place “Havnor” as invented by Ursula K. Le Guin for her “Earthsea” book series, the related maps and appearing in derivative works based on these novels

In First Order Logic:
- E89(x) ⇒ E28(x)
C. Scope note:
This class comprises identifiable symbols and any aggregation of symbols, such as characters, identifiers, traffic signs, emblems, texts, data sets, images, musical scores, multimedia objects, computer program code, or mathematical formulae that have an objectively recognizable structure and that are documented as single units.
It includes sets of signs of any nature, which may serve to designate something, or to communicate some propositional content. An instance of the concept may or may not have a specific meaning, for example an arbitrary character string.
In some cases, the content of an instance of the concept may completely be represented by a serialized digital content model, such as a sequence of ASCII-encoded characters, an XML or HTML document, or a TIFF image. The property P3 has note and its subproperty P190 has symbolic content allow for the description of this content model. In order to disambiguate which symbolic level is the carrier of the meaning, the property P3.1 has type can be used to specify the encoding (e.g. “bit”, “Latin character”, RGB pixel).

Examples:
- ‘ecognizabl’
- the “no-smoking” sign (E36)
- “BM000038850.JPG” (E41) [identifies a digital image] (Natural History Museum, 2021)
- image BM000038850.JPG from the Clayton Herbarium in London (E36) [depicts specimen of Verbesina virginica] (Natural History Museum, 2021)
- the distribution of form, tone and colour found on Leonardo da Vinci’s painting named “Mona Lisa” in daylight (E36)
- the Italian text of Dante’s “Divina Commedia” as found in the authoritative critical edition “La Commedia secondo l’antica vulgata a cura di Giorgio Petrocchi” (E33) (Petrocchi, 1967)

In First Order Logic:
- E90(x) ⇒ E28(x)
- E90(x) ⇒ E72(x)
D. Scope note:
This class comprises all signs, either meaningful or not, or arrangements of signs following a specific syntax, that are used or can be used to refer to and identify a specific instance of some class within a certain context.
Instances of the concept do not identify things by their meaning, even if they happen to have one, but by convention, tradition, or agreement. Instances of the concept are cultural constructs; as such, they have a context, a history, and a use in time and space by some group of users. A given instance of the concept can have alternative forms, i.e. other instances of the concept that are regarded as equivalent, regardless of the thing it denotes.
Different languages may use different appellations for the same thing, such as the names of major cities. Some appellations may be formulated using a valid noun phrase of a particular language. In these cases, the respective instances of the concept should also be declared as instances of E33 Linguistic Object. Then the language using the the concept can be declared with the property P72 has language: E56 Language.
Instances of the concept may be used to identify any instance of E1 CRM Entity and sometimes are characteristic for instances of more specific subclasses of E1 CRM Entity, such as for instances of E52 Time-Span (for instance “dates”), E39 Actor, E53 Place or E28 Conceptual Object. Postal addresses and E-mail addresses are characteristic examples of identifiers used by services transporting things between clients.
Even numerically expressed identifiers for extents in space or time are also regarded as instances of the concept, such as Gregorian dates or spatial coordinates, even though they allow for determining some time or location by a known procedure starting from a reference point and by virtue of that fact play a double role as instances of E59 Primitive Value.
the concept should not be confused with the act of naming something. Cf. E15 Identifier Assignment.

Examples:
- “Martin”
- “Aquae Sulis Minerva”
- “the Merchant of Venice” (E35) (McCullough, 2005)
- “Spigelia marilandica (L.) L.” [not the species, just the name] (Hershberger, Robacker and Jenkins, 2015)
- “information science” [not the science itself, but the name used to refer to the subject matter in an English-speaking context]
- “安” [Chinese “an”, meaning “peace”]
- “6°5’29”N 45°12’13”W” [example of a spatial coordinate]
- “Black queen’s bishop 4” [chess coordinate, example of an identifier in a conceptual space (E89)]
- “19-MAR-1922” [example of date]
- “+41 22 418 5571” [example of contact point]
- “weasel@paveprime.com” [example of contact point]
- “CH-1211, Genève” [example of place the concept]
- “1-29-3 Otsuka, Bunkyo-ku, Tokyo, 121, Japan” [example of a postal address]
- “the poop deck of H.M.S Victory” [example of a section definition on a human-made object (E22)]
- “the Venus de Milo’s left buttock” [example of a section definition on a human-made object (E22)]

In First Order Logic:
- E41(x) ⇒ E90(x)
