E93 Spacetime Snapshot

Description

Scope note:
This class comprises instances of E92 Spacetime Volume that result from intersection of instances of
E92 Spacetime Volume with an instance of E52 Time-Span. The identity of an instance of this class is determined by the identities of the constituing spacetime volume and the time-span. This class can be used to define temporal snapshots at a particular time-span, such as the extent of the Roman Empire at 33 B.C., or the extent occupied by a museum object at rest in an exhibit. In particular, it can be used to define the spatial projection of a spacetime volume during a particular time-span, such as the maximal spatial extent of a flood at some particular hour, or all areas covered by the Poland within the 20th century AD

In First Order Logic:
E93(x) ⊃ E92(x)

Usage

Instances of crm:E93_Presence can have the following properties:

PROPERTYTYPEDESCRIPTIONRANGE
From class crm:E93_Presence
crm:P162_is_restricted_by owl:ObjectProperty Scope note: This property relates an E93 Spacetime Snapshot with an arbitrary E92Spacetime Volume that restricts the extent of the former to a volume equal to or within the latter. Examples: crm:E92_Spacetime_Volume
crm:P163_is_restricted_by owl:ObjectProperty Scope note: This property relates an E93 Spacetime Snapshot with an arbitrary instance of E53 Place that restricts the extent of the former to a volume within the back-projection of the instance of E53 Place to all times. If the instance of E53 Place is defined in two dimensions only, such as the footprint of a building, the place needs also to be back-projected into the third dimension. Examples: crm:E53_Place
crm:P164_during owl:ObjectProperty Scope note: This property relates an E93 Presence with an arbitrary E52 Time-Span that defines the section of the spacetime volume that this instance of E93 Presence is related to by P166 was a presence of (had presence). that is concerned by this instance of E93 Presence. Examples: In First Order Logic: P164 (x,y) ⊃ E93(x) P164 (x,y) ⊃ E52(y) crm:E52_Time-Span
crm:P166_was_a_presence_of owl:ObjectProperty Scope Note: This property relates an E93 Presence with the STV it is part of... In First Order Logic: P166(x,y) ⊃ E93(x) P166(x,y) ⊃ E92(y) crm:E92_Spacetime_Volume
crm:P167_was_at owl:ObjectProperty Scope Note: This property points to a wider area in which my thing /event was ... In First Order Logic: P167(x,y) ⊃ E93(x) P167(x,y) ⊃ E53(y) crm:E53_Place
From class crm:E92_Spacetime_Volume
crm:P10_falls_within owl:ObjectProperty Scope note: This property associates an instance of E4 Period with another instance of E4 Period that falls within the spacetime volumes occupied by the latter. The difference with P9 consists of (forms part of) is subtle. Unlike P9 consists of (forms part of), P10 falls within (contains) does not imply any logical connection between the two periods and it may refer to a period of a completely different nature. Examples: - the Great Plague (E4) falls within The Gothic period (E4) crm:E92_Spacetime_Volume
crm:P10i_contains owl:ObjectProperty crm:E92_Spacetime_Volume
crm:P132_overlaps_with owl:ObjectProperty Scope note: This symmetric property allows instances of E4 Period that overlap both temporally and spatially to be related, i,e. they share some spatio-temporal extent. This property does not imply any ordering or sequence between the two periods, either spatial or temporal. Examples: - the "Urnfield" period (E4) overlaps with the "Hallstatt" period (E4) In First Order Logic: P132(x,y) ⊃ E92(x) P132(x,y) ⊃ E92(y) P132(x,y) ⊃ P132(y,x) crm:E92_Spacetime_Volume
crm:P133_is_separated_from owl:ObjectProperty Scope note: This symmetric property allows instances of E4 Period that do not overlap both temporally and spatially, to be related i,e. they do not share any spatio-temporal extent. This property does not imply any ordering or sequence between the two periods either spatial or temporal. Examples: - the "Hallstatt" period (E4) is separated from the "La Tène" era (E4) In First Order Logic: P133(x,y) ⊃ E92(x) P133(x,y) ⊃ E92(y) P133(x,y) ⊃ P133(y,x) crm:E92_Spacetime_Volume
crm:P160_has_temporal_projection owl:ObjectProperty Scope note: This property describes the temporal projection of an instance of an E92 Spacetime Volume. The property P4 has time-span is the same as P160 has temporal projection if it is used to document an instance of E4 Period or any subclass of it. Example: In First Order Logic: P160(x,y) ⊃ E92(x) P160(x,y)⊃ E52(y) crm:E52_Time-Span
crm:P161_has_spatial_projection owl:ObjectProperty Scope note: This property associates an instance of a E92 Spacetime Volume with an instance of E53 Place that is the result of the spatial projection of the instance of a E92 Spacetime Volume on a reference space. In general there can be more than one useful reference space to describe the spatial projection of a spacetime volume, such as that of a battle ship versus that of the seafloor. Therefore the projection is not unique. This is part of the fully developed path that is shortcut by P7took place at (witnessed. The more fully developed path from E4 Period through P161 has spatial projection, E53 Place, P89 falls within (contains) to E53 Place. Example In First Order Logic: P161(x,y) ⊃ E92(x) P161(x,y) ⊃ E53(y) crm:E53_Place
crm:P166i_had_presence owl:ObjectProperty crm:E93_Presence
From class crm:E1_CRM_Entity
crm:P3_has_note owl:DatatypeProperty Scope note: This property is a container for all informal descriptions about an object that have not been expressed in terms of CRM constructs. In particular it captures the characterisation of the item itself, its internal structures, appearance etc. Like property P2 has type (is type of), this property is a consequence of the restricted focus of the CRM. The aim is not to capture, in a structured form, everything that can be said about an item; indeed, the CRM formalism is not regarded as sufficient to express everything that can be said. Good practice requires use of distinct note fields for different aspects of a characterisation. The P3.1 has type property of P3 has note allows differentiation of specific notes, e.g. "construction", "decoration" etc. An item may have many notes, but a note is attached to a specific item. Examples: - coffee mug - OXCMS:1983.1.1 (E19) has note "chipped at edge of handle" (E62) has type Condition (E55) In First Order Logic: P3(x,y) ⊃ E1(x) P3(x,y) ⊃ E62(y) P3(x,y,z) ⊃ [P3(x,y) ∧ E55(z)] Properties: P3.1 has type: E55 Type owl:Thing
crm:P129i_is_subject_of owl:ObjectProperty crm:E89_Propositional_Object
crm:P136i_supported_type_creation owl:ObjectProperty crm:E83_Type_Creation
crm:P137_exemplifies owl:ObjectProperty Scope note: This property allows an item to be declared as a particular example of an E55 Type or taxon The P137.1 in the taxonomic role property of P137 exemplifies (is exemplified by) allows differentiation of taxonomic roles. The taxonomic role renders the specific relationship of this example to the Type, such as "prototypical", "archetypical", "lectotype", etc. The taxonomic role "lectotype" is not associated with the Type Creation (E83) itself, but selected in a later phase. Examples: - Object BM000098044 of the Clayton Herbarium (E20) exemplifies Spigelia marilandica (L.) L. (E55) in the taxonomic role lectotype In First Order Logic: P137(x,y) ⊃ E1(x) P137(x,y) ⊃ E55(y) P137(x,y,z) ⊃ [P137(x,y) ∧ E55(z)] P137(x,y) ⊃ P2(x,y) Properties: P137.1 in the taxonomic role: E55 Type crm:E55_Type

crm:P140i_was_attributed_by owl:ObjectProperty crm:E13_Attribute_Assignment

crm:P15i_influenced owl:ObjectProperty crm:E7_Activity
crm:P17i_motivated owl:ObjectProperty crm:E7_Activity
crm:P1_is_identified_by owl:ObjectProperty Scope note: This property describes the naming or identification of any real world item by a name or any other identifier. This property is intended for identifiers in general use, which form part of the world the model intends to describe, and not merely for internal database identifiers which are specific to a technical system, unless these latter also have a more general use outside the technical context. This property includes in particular identification by mathematical expressions such as coordinate systems used for the identification of instances of E53 Place. The property does not reveal anything about when, where and by whom this identifier was used. A more detailed representation can be made using the fully developed (i.e. indirect) path through E15 Identifier Assignment. Examples: - the capital of Italy (E53) is identified by "Rome" (E48) - text 25014-32 (E33) is identified by "The Decline and Fall of the Roman Empire" (E35) In First Order Logic: P1(x,y) ⊃ E1(x) P1(x,y) ⊃ E41(y) crm:E41_Appellation
crm:P2_has_type owl:ObjectProperty Scope note: This property allows sub typing of CRM entities - a form of specialisation – through the use of a terminological hierarchy, or thesaurus. The CRM is intended to focus on the high-level entities and relationships needed to describe data structures. Consequently, it does not specialise entities any further than is required for this immediate purpose. However, entities in the isA hierarchy of the CRM may by specialised into any number of sub entities, which can be defined in the E55 Type hierarchy. E51 Contact Point, for example, may be specialised into "e-mail address", "telephone number", "post office box", "URL" etc. none of which figures explicitly in the CRM hierarchy. Sub typing obviously requires consistency between the meaning of the terms assigned and the more general intent of the CRM entity in question. Examples: - "enquiries@cidoc-crm.org" (E51) has type e-mail address (E55) In First Order Logic: P2(x,y) ⊃ E1(x) P2(x,y) ⊃ E55(y) crm:E55_Type
crm:P39i_was_measured_by owl:ObjectProperty crm:E16_Measurement
crm:P41i_was_classified_by owl:ObjectProperty crm:E17_Type_Assignment
crm:P62i_is_depicted_by owl:ObjectProperty crm:E24_Physical_Man-Made_Thing

crm:P70i_is_documented_in owl:ObjectProperty crm:E31_Document

crm:P22i_acquired_title_through owl:InverseFunctionalProperty crm:E8_Acquisition
crm:P23i_surrendered_title_through owl:ObjectProperty crm:E8_Acquisition
crm:P28i_surrendered_custody_through owl:ObjectProperty crm:E10_Transfer_of_Custody
crm:P29i_received_custody_through owl:ObjectProperty crm:E10_Transfer_of_Custody
crm:P48_has_preferred_identifier owl:ObjectProperty 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) crm:E42_Identifier
