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

Which of the following definitions best describes 'E11 Modification'?

A. Scope note:
This class comprises instances of E7 Activity that are undertaken to create, alter or change instances of E24 Physical Human-Made Thing.
This class includes the production of an item from raw materials and other so far undocumented objects. It also includes the conservation treatment of an object.
Since the distinction between the concept and production is not always clear, the concept is regarded as the more generally applicable concept. This implies that some items may be consumed or destroyed in an instance of the concept, and that others may be produced as a result of it. An event should also be documented using an instance of E81 Transformation if it results in the destruction of one or more objects and the simultaneous production of others using parts or material from the originals. In this case, the new items have separate identities.
An activity undertaken on an object which was designed to alter it, but which, in fact, it did not in any seemingly significant way (such as the application of a solvent during conservation which failed to dissolve any part of the object), is still considered as an instance of the concept. Typically, any such activity will leave at least forensic traces of evidence on the object.
If the instance of E29 Design or Procedure utilized for the the concept prescribes the use of specific materials, they should be documented using property P68 foresees use of (use foreseen by): E57 Material of E29 Design or Procedure, rather than via P126 employed (was employed in): E57 Material.

Examples:
- the construction of the SS Great Britain (E12) (Gregor, 1971)
- the impregnation of the Vasa warship in Stockholm for preservation after 1956 (Håfors, 2010)
- the transformation of the Enola Gay into a museum exhibit by the National Air and Space Museum in Washington DC between 1993 and 1995 (E12, E81) (Yakel, 2000)
- the last renewal of the gold coating of the Toshogu shrine in Nikko, Japan (Cali and Dougil, 2012)

In First Order Logic:
- E11(x) ⇒ E7(x)
B. Scope note:
This class comprises the activities that result in an instance of E39 Actor becoming a member of an instance of E74 Group. This class does not imply initiative by either party. It may be the initiative of a third party.
Typical scenarios include becoming a member of a social organisation, becoming an employee of a company, marriage, the adoption of a child by a family, and the inauguration of somebody into an official position.

Examples:
- the election of Sir Isaac Newton as Member of Parliament for the University of Cambridge to the Convention Parliament of 1689 (Gleick, 2003)
- the inauguration of Mikhail Sergeyevich Gorbachev as leader of the Union of Soviet Socialist Republics (USSR) in 1985 (Butson, 1986)
- the implementation of the membership treaty between EU and Denmark, 1(st) January 1993

In First Order Logic:
- E85(x) ⇒ E7(x)
C. Scope note:
This class comprises activities that are designed to, and succeed in, creating one or more new items. 
It specializes the notion of modification into the concept. The decision as to whether or not an object is regarded as new is context sensitive. Normally, items are considered “new” if there is no obvious overall similarity between them and the consumed items and material used in their the concept. In other cases, an item is considered “new” because it becomes relevant to documentation by a modification. For example, the scribbling of a name on a potsherd may make it a voting token. The original potsherd may not be worth documenting, in contrast to the inscribed one. 
This entity can be collective: the printing of a thousand books, for example, would normally be considered a single event. 
An event should also be documented using an instance of E81 Transformation if it results in the destruction of one or more objects and the simultaneous the concept of others using parts or material from the originals. In this case, the new items have separate identities and matter is preserved, but identity is not.

Examples:
- the construction of the SS Great Britain (Gregor, 1971)
- the first casting of the Little Mermaid from the harbour of Copenhagen (Dewey, 2003)
- Rembrandt’s creating of the seventh state of his etching “Woman sitting half dressed beside a stove”, 1658, identified by Bartsch Number 197 (E12, E65, E81) (Hind, 1923)

In First Order Logic:
- E12(x) ⇒ E11(x)
- E12(x) ⇒ E63(x)
D. Scope note:
This class comprises the actions of making assertions about one property of an object or any single relation between two items or concepts. The type of the property asserted to hold between two items or concepts can be described by the property P177 assigned property of type (is type of property assigned): E55 Type. 
For example, the class describes the actions of people making propositions and statements during certain scientific/scholarly procedures, e.g. the person and date when a condition statement was made, an identifier was assigned, the museum object was measured, etc. Which kinds of such assignments and statements need to be documented explicitly in structures of a schema rather than free text, depends on whether this information should be accessible by structured queries.
This class allows for the documentation of how the respective assignment came about, and whose opinion it was. Note that all instances of properties described in a knowledge base are the opinion of someone. Per default, they are the opinion of the team maintaining the knowledge base. This fact must not individually be registered for all instances of properties provided by the maintaining team, because it would result in an endless recursion of whose opinion was the description of an opinion. Therefore, the use of instances of the concept marks the fact that the maintaining team is in general neutral to the validity of the respective assertion, but registers someone else’s opinion and how it came about.
All properties assigned in such an action can also be seen as directly relating the respective pair of items or concepts. Multiple use of instances of the concept may possibly lead to a collection of contradictory values.

Examples:
- the examination of MS Sinai Greek 418 by Nicholas Pickwoad in November 2003 (Honey & Pickwoad, 2010)
- the assessment of the current ownership of Martin Doerr’s silver cup in February 1997 (fictitious)

In First Order Logic:
- E13(x) ⇒ E7(x)

Answer: Scope note:
This class comprises instances of E7 Activity that are undertaken to create, alter or change instances of E24 Physical Human-Made Thing.

This implies that some items may be consumed or destroyed in an instance of the concept, and that others may be produced as a result of it. An event should also be documented using an instance of E81 Transformation if it results in the destruction of one or more objects and the simultaneous production of others using parts or material from the originals.

An activity undertaken on an object which was designed to alter it, but which, in fact, it did not in any seemingly significant way (such as the application of a solvent during conservation which failed to dissolve any part of the object), is still considered as an instance of the concept. Typically, any such activity will leave at least forensic traces of evidence on the object.
If the instance of E29 Design or Procedure utilized for the the concept prescribes the use of specific materials, they should be documented using property P68 foresees use of (use foreseen by): E57 Material of E29 Design or Procedure, rather than via P126 employed (was employed in): E57 Material.

- the construction of the SS Great Britain (E12) (Gregor, 1971)

- the last renewal of the gold coating of the Toshogu shrine in Nikko, Japan (Cali and Dougil, 2012)
