This property identifies the E18 Physical Thing that is added during an E79 Part Addition activity

This property identifies the E18 Physical Thing that is removed during an E80 Part Removal activity.

This property allows specific instances of E18 Physical Thing that have been destroyed to be related to a destruction event. Destruction implies the end of an item’s life as a subject of cultural documentation – the physical matter of which the item was composed may in fact continue to exist. A destruction event may be contiguous with a Production that brings into existence a derived object composed partly of matter from the destroyed object.

This property associates an instance of P53 Place with the instance of E18 Physical Thing that determines a reference space for this instance of P53 Place by being at rest with respect to this reference space. The relative stability of form of an E18 Physical Thing defines its default reference space. The reference space is not spatially limited to the referred thing. For example, a ship determines a reference space in terms of which other ships in its neighbourhood may be described. Larger constellations of matter, such as continental plates, may comprise many physical features that are at rest with them and define the same reference space.

This property identifies the E18 Physical Thing or things involved in an E8 Acquisition. In reality, an acquisition must refer to at least one transferred item.

This property identifies an item or items of E18 Physical Thing concerned in an E10 Transfer of Custody activity. The property will typically describe the object that is handed over by an E39 Actor to another Actor’s custody. On occasion, physical custody may be transferred involuntarily or illegally – through accident, unsolicited donation, or theft.

This property identifies the E18 Physical Thing that was assessed during an E14 Condition Assessment activity. Conditions may be assessed either by direct observation or using recorded evidence. In the latter case the E18 Physical Thing does not need to be present or extant.

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).

This property describes the location of an instance of E4 Period with respect to an E19 Physical Object. P8 took place on or within (witnessed) is a shortcut of the more fully developed path from E4 Period through P7 took place at, E53 Place, P156 occupies (is occupied by) to E18 Physical Thing. It describes a period that can be located with respect to the space defined by an E19 Physical Object such as a ship or a building. The precise geographical location of the object during the period in question may be unknown or unimportant. For example, the French and German armistice of 22 June 1940 was signed in the same railway carriage as the armistice of 11 November 1918.
