P46 is composed of (forms part of)

Domain: E18 Physical Thing

Range: E18 Physical Thing

Subproperty of: E92 Spacetime Volume. P132 overlaps with: E92 Spacetime Volume

Superproperty of:E19 Physical Object. P56 bears feature (is found on): E26 Physical Feature

Quantification: many to many (0,n:0,n)


Scope note: This property allows instances of E18 Physical Thing to be analysed into component elements.
Component elements, since they are themselves instances of E18 Physical Thing, may be further analysed into sub-components, thereby creating a hierarchy of part decomposition. An instance of E18 Physical Thing may be shared between multiple wholes, for example two buildings may share a common wall. This property does not specify when and for how long a component element resided in the respective whole. If a component is not part of a whole from the beginning of existence or until the end of existence of the whole, the classes E79 Part Addition and E90 Part Removal can be used to document when a component became part of a particular whole and/or when it stopped being a part of it. For the time-span of being part of the respective whole, the component is completely contained in the place the whole occupies.
This property is intended to describe specific components that are individually documented, rather than general aspects. Overall descriptions of the structure of an instance of E18 Physical Thing are captured by the P3 has note property.
The instances of E57 Material of which an item of E18 Physical Thing is composed should be documented using P45 consists of (is incorporated in).

Examples:



  • the Royal carriage (E22) forms part of the Royal train (E22)

  • the “Hog’s Back” (E24) forms part of the “Fosseway” (E24)

In First Order Logic:

P46(x,y) ⊃ E18(x)

P46(x,y) ⊃ E18(y)

P46(x,y) ⊃ P132(x,y)

P46(x,y) ⊃ (uzw)[E93(u) ∧ P166 (x,u) ∧ E52(z) ∧ P164(u,z) ∧ E93(w) ∧ P166 (y,w) ∧

P164(w,z) ∧ P10(w,u)]

P48 has preferred identifier (is preferred identifier of)


Domain: E1 CRM Entity

Range: E42 Identifier

Subproperty of: E1 CRM Entity.P1 is identified by (identifies): E41 Appellation

Quantification: many to one (0,1:0,n)


Scope note: This property records the preferred E42 Identifier that was used to identify an instance of E1 CRM Entity at the time this property was recorded.
More than one preferred identifier may have been assigned to an item over time.

Use of this property requires an external mechanism for assigning temporal validity to the respective CRM instance.


P48 has preferred identifier (is preferred identifier of), is a shortcut for the path from E1 CRM Entity through P140 assigned attribute to (was attributed by), E15 Identifier Assignment, P37 assigned (was assigned by) to E42 Identifier. The fact that an identifier is a preferred one for an organisation can be better expressed in a context independent form by assigning a suitable E55 Type to the respective instance of E15 Identifier Assignment using the P2 has type property.

Examples:



  • the pair of Lederhosen donated by Dr Martin Doerr (E22) has preferred identifier “OXCMS:2001.1.32” (E42)

In First Order Logic:

P48(x,y) ⊃ E1(x)

P48(x,y) ⊃ E42(y)

P48(x,y) ⊃ P1(x,y)

P49 has former or current keeper (is former or current keeper of)


Domain: E18 Physical Thing

Range: E39 Actor

Superproperty of: E18 Physical Thing. P50 has current keeper (is current keeper of): E39 Actor

E78 Collection.P109 has current or former curator (is current or former curator of):E39 Actor

Quantification: many to many (0,n:0,n)
Scope note: This property identifies the E39 Actor or Actors who have or have had custody of an instance of E18 Physical Thing at some time. This property leaves open the question if parts of this physical thing have been added or removed during the time-spans it has been under the custody of this actor, but it is required that at least a part which can unambiguously be identified as representing the whole has been under this custody for its whole time. The way, in which a representative part is defined, should ensure that it is unambiguous who keeps a part and who the whole and should be consistent with the identity criteria of the kept instance of E18 Physical Thing.

The distinction with P50 has current keeper (is current keeper of) is that P49 has former or current keeper (is former or current keeper of) leaves open the question as to whether the specified keepers are current.


P49 has former or current keeper (is former or current keeper of) is a shortcut for the more detailed path from E18 Physical Thing through P30 transferred custody of (custody transferred through), E10 Transfer of Custody, P28 custody surrendered by (surrendered custody through) or P29 custody received by (received custody through) to E39 Actor.

Examples:


In First Order Logic:

P49(x,y) ⊃ E18(x)

P49(x,y) ⊃ E39(y)



P50 has current keeper (is current keeper of)


Domain: E18 Physical Thing

Range: E39 Actor

Subproperty of: E18 Physical Thing. P49 has former or current keeper (is former or current keeper of): E39 Actor

Quantification: many to many (0,n:0,n)


Scope note: This property identifies the E39 Actor or Actors who had custody of an instance of E18 Physical Thing at the time of validity of the record or database containing the statement that uses this property.
P50 has current keeper (is current keeper of) is a shortcut for the more detailed path from E18 Physical Thing through P30 transferred custody of (custody transferred through), E10 Transfer of Custody, P29 custody received by (received custody through) to E39 Actor.

Examples:



  • paintings from The Iveagh Bequest (E18) has current keeper The National Gallery (E40)

In First Order Logic:

P50(x,y) ⊃ E18(x)

P50(x,y) ⊃ E39(y)

P50(x,y) ⊃ P49(x,y)
