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

Which of the following definitions best describes 'E96 Purchase'?

A. Scope note:
This class comprises the units in which a monetary system, supported by an administrative authority or other community, quantifies and arithmetically compares all monetary amounts declared in the unit. The unit of a monetary system must describe a nominal value which is kept constant by its administrative authority and an associated banking system if it exists, and not by market value. For instance, one may pay with grams of gold, but the respective monetary amount would have been agreed as the gold price in US dollars on the day of the payment. Under this definition, British Pounds, U.S. Dollars, and European Euros are examples of the concept, but “grams of gold” is not. One monetary system has one and only one the concept. Instances of this class must not be confused with coin denominations, such as “Dime” or “Sestertius”. Non-monetary exchange of value in terms of quantities of a particular type of goods, such as cows, do not constitute a the concept.

Examples:
- “As” [Roman mid republic]
- “Euro” (Temperton, 1997)
- “US Dollar” (Rose, 1978)

In First Order Logic:
- E98(x) ⇒ E58(x)
B. Scope note:
This class is a specialization of E55 Type and comprises the natural languages in the sense of concepts.
This type is used categorically in the model without reference to instances of it, i.e. the Model does not foresee the description of instances of instances of the concept, e.g. “instances of Mandarin Chinese”.
It is recommended that internationally or nationally agreed codes and terminology should be used to denote instances of the concept, such as those defined in ISO 639-3:2007 and later versions.

Examples:
- ell [Greek] 
- eng [English] 
- epo [Esperanto] 
- spa [Spanish] 
- fra [French]

In First Order Logic:
- E56(x) ⇒ E55(x)
C. Scope note:
This class comprises transfers of legal ownership from one or more instances of E39 Actor to one or more different instances of E39 Actor, where the transferring party is completely compensated by the payment of a monetary amount. In more detail, a the concept agreement establishes a fixed monetary obligation at its initialization on the receiving party, to the giving party. An instance of the concept begins with the contract or equivalent agreement and ends with the fulfilment of all contractual obligations. In the case that the activity is abandoned before both parties have fulfilled these obligations, the activity is not regarded as an instance of the concept.
This class is a very specific case of the much more complex social business practices of exchange of goods and the creation and satisfaction of related social obligations. the concept activities which define individual sales prices per object can be modelled by instantiating the concept for each object individually and as part of an overall instance of the concept transaction.

Examples:
- the the concept of 10 okka of nails by the captain A. Syrmas on 18(th) September 1895 in Thessaloniki (Syrmas, 1896)

In First Order Logic:
- E96(x) ⇒ E8(x)
D. 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)
