E2 Temporal Entity

Description

Scope note:
This class comprises all phenomena, such as the instances of E4 Periods, E5 Events and states, which happen over a limited extent in time. This extent in time must be contiguous, i.e., without gaps. In case the defining kinds of phenomena for an instance of E2 Temporal Entity cease to happen, and occur
later again at another time, we regard that the former E2 Temporal Entity has ended and a new instance has come into existence. In more intuitive terms, the same event cannot happen twice.

In some contexts, these are also called perdurants. This class is disjoint from E77 Persistent Item. This is an abstract class and has no direct instances. E2 Temporal Entity is specialized into E4 Period, which applies to a particular geographic area (defined with a greater or lesser degree of precision), and E3 Condition State, which applies to instances of E18 Physical Thing.

Examples:
- Bronze Age (E4)
- the earthquake in Lisbon 1755 (E5)
- the Peterhof Palace near Saint Petersburg being in ruins from 1944 – 1946 (E3)

In First Order Logic:
E2(x) ⊃ E1(x)

Usage

Instances of crm:E2_Temporal_Entity can have the following properties:

PROPERTYTYPEDESCRIPTIONRANGE
From class crm:E2_Temporal_Entity
crm:P114_is_equal_in_time_to owl:ObjectProperty Scope note: This symmetric property allows the instances of E2 Temporal Entity with the same E52 Time-Span to be equated. This property is only necessary if the time span is unknown (otherwise the equivalence can be calculated). This property is the same as the "equal" relationship of Allen’s temporal logic (Allen, 1983, pp. 832-843). Examples: - the destruction of the Villa Justinian Tempus (E6) is equal in time to the death of Maximus Venderus (E69) In First Order Logic: P114(x,y) ⊃ E2(x) P114(x,y) ⊃ E2(y) P114(x,y) ⊃ P114(y,x) crm:E2_Temporal_Entity
crm:P115_finishes owl:ObjectProperty Scope note: This property allows the ending point for a E2 Temporal Entity to be situated by reference to the ending point of another temporal entity of longer duration. This property is only necessary if the time span is unknown (otherwise the relationship can be calculated). This property is the same as the "finishes / finished-by" relationships of Allen’s temporal logic (Allen, 1983, pp. 832-843). Examples: - Late Bronze Age (E4) finishes Bronze Age (E4) In First Order Logic: P115(x,y) ⊃ E2(x) P115(x,y) ⊃ E2(y) crm:E2_Temporal_Entity
crm:P115i_is_finished_by owl:ObjectProperty crm:E2_Temporal_Entity
crm:P116_starts owl:ObjectProperty Scope note: This property allows the starting point for a E2 Temporal Entity to be situated by reference to the starting point of another temporal entity of longer duration. This property is only necessary if the time span is unknown (otherwise the relationship can be calculated). This property is the same as the "starts / started-by" relationships of Allen’s temporal logic (Allen, 1983, pp. 832-843). Examples: - Early Bronze Age (E4) starts Bronze Age (E4) In First Order Logic: P116(x,y) ⊃ E2(x) P116(x,y) ⊃ E2(y) crm:E2_Temporal_Entity
crm:P116i_is_started_by owl:ObjectProperty crm:E2_Temporal_Entity
crm:P117_occurs_during owl:ObjectProperty Scope note: This property allows the entire E52 Time-Span of an E2 Temporal Entity to be situated within the Time-Span of another temporal entity that starts before and ends after the included temporal entity. This property is only necessary if the time span is unknown (otherwise the relationship can be calculated). This property is the same as the "during / includes" relationships of Allen’s temporal logic (Allen, 1983, pp. 832-843). Examples: - Middle Saxon period (E4) occurs during Saxon period (E4) In First Order Logic: P117(x,y) ⊃ E2(x) P117(x,y) ⊃ E2(y) crm:E2_Temporal_Entity
crm:P117i_includes owl:ObjectProperty crm:E2_Temporal_Entity
crm:P118_overlaps_in_time_with owl:ObjectProperty Scope note: This property identifies an overlap between the instances of E52 Time-Span of two instances of E2 Temporal Entity. It implies a temporal order between the two entities: if A overlaps in time B, then A must start before B, and B must end after A. This property is only necessary if the relevant time spans are unknown (otherwise the relationship can be calculated). This property is the same as the "overlaps / overlapped-by" relationships of Allen’s temporal logic (Allen, 1983, pp. 832-843). Examples: - the Iron Age (E4) overlaps in time with the Roman period (E4) In First Order Logic: P118(x,y) ⊃ E2(x) P118(x,y) ⊃ E2(y) crm:E2_Temporal_Entity
crm:P118i_is_overlapped_in_time_by owl:ObjectProperty crm:E2_Temporal_Entity
crm:P119_meets_in_time_with owl:ObjectProperty Scope note: This property indicates that one E2 Temporal Entity immediately follows another. It implies a particular order between the two entities: if A meets in time with B, then A must precede B. This property is only necessary if the relevant time spans are unknown (otherwise the relationship can be calculated). This property is the same as the "meets / met-by" relationships of Allen's temporal logic (Allen, 1983, pp. 832-843). Examples: - Early Saxon Period (E4) meets in time with Middle Saxon Period (E4) crm:E2_Temporal_Entity
crm:P119i_is_met_in_time_by owl:ObjectProperty crm:E2_Temporal_Entity
crm:P120_occurs_before owl:ObjectProperty Scope note: This property identifies the relative chronological sequence of two temporal entities. It implies that a temporal gap exists between the end of A and the start of B. This property is only necessary if the relevant time spans are unknown (otherwise the relationship can be calculated). This property is the same as the "before / after" relationships of Allen’s temporal logic (Allen, 1983, pp. 832-843). Examples: - Early Bronze Age (E4) occurs before Late Bronze age (E4) In First Order Logic: P120(x,y) ⊃ E2(x) P120(x,y) ⊃ E2(y) crm:E2_Temporal_Entity
crm:P120i_occurs_after owl:ObjectProperty crm:E2_Temporal_Entity
crm:P4_has_time-span owl:ObjectProperty Scope note: This property describes the temporal confinement of an instance of an E2 Temporal Entity. The related E52 Time-Span is understood as the real Time-Span during which the phenomena were active, which make up the temporal entity instance. It does not convey any other meaning than a positioning on the "time-line" of chronology. The Time-Span in turn is approximated by a set of dates (E61 Time Primitive). A temporal entity can have in reality only one Time-Span, but there may exist alternative opinions about it, which we would express by assigning multiple Time-Spans. Related temporal entities may share a Time-Span. Time-Spans may have completely unknown dates but other descriptions by which we can infer knowledge. Examples: - the Yalta Conference (E7) has time-span Yalta Conference time-span (E52) In First Order Logic: P4(x,y) ⊃ E2(x) P4(x,y) ⊃ E52(y) crm:E52_Time-Span
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:P138i_has_representation owl:ObjectProperty crm:E36_Visual_Item
crm:P140i_was_attributed_by owl:ObjectProperty crm:E13_Attribute_Assignment
crm:P141i_was_assigned_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: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
crm:P50i_is_current_keeper_of owl:ObjectProperty crm:E18_Physical_Thing
crm:P52i_is_current_owner_of owl:ObjectProperty crm:E18_Physical_Thing
