Issue 453: declarative time-spans

ID: 
453
Starting Date: 
2019-10-25
Working Group: 
3
Status: 
Open
Background: 

In the 45th joint meeting of the CIDOC CRM SIG and SO/TC46/SC4/WG9; 38th FRBR – CIDOC CRM Harmonization meeting, the  sig reworked the scope note for P4 has time-span (is time-span of) on the basis that it expressed epistemological notions rather than defining what a time-span is. In a similar vein, it was decided that a new issue should start to explain that shared time-spans can only be declarative ones –not phenomenal and the scope note of P4 should be updated appropriately.

The old and the new working scope note of P4 can be found here.

Current Proposal: 

In the 46th joint meeting of the CIDOC CRM SIG and ISO/TC46/SC4/WG9; 39th FRBR - CIDOC CRM Harmonization meeting; During the discussion about issue 459 and reviewing the  Figure 4 : Temporal Informationedited the cardinalities for P4 has time span and P170 defines time.

  • the cardinality of P4 has time-span [D: E2 Temporal Entity; R: E52 Time-Span] changed from (1,1:1,n) to (0,1:0,n), and
  • the cardinality of P170 defines time [D: E61 Time Primitive; R: E52 Time-Span] changed from (1,1:0,n) to (0,1:0,n).

Dear all,

Please, find my HW for the issue attached

Dear All,

The property P164 during (was time-span of) was renamed following the decision by CRM-SIG to become: P164 is temporally specified by (temporally specifies). It was decided to add a paragraph about the nature of the time-span used as range.

OLD
P164 during (was time-span of)
Domain: E93 Presence
Range: E52 Time-Span

Subproperty of:   E92 Spacetime Volume.P160 has temporal projection: E52 Time-Span
Quantification:     (1,1 :0,n)
 
Scope note:                 This property relates an instance of E93 Presence with the chosen instance of E52 Time-Span that defines the time-slice of the spacetime volume that this instance of E93 Presence is related to by the property P166 was a presence of (had presence).

Examples:

▪        2016-02-09 (E52) was time-span of the last day of the 2016 Carnival in Cologne (E93).
▪        Johann JoachimWinckelmann’s whereabouts in December 1755 (E93) during December 1755 (E52)
▪        Johann Joachim Winkelmann’s whereabouts from November 19 1755 until April 9 1768 (E93) during November 19 1755 until April 9 1768 (E52)

In First Order Logic:

                           P164 (x,y) ⊃ E93(x)
                           P164 (x,y) ⊃ E52(y)
                           P164 (x,y) ⊃ P160(x,y)

NEW

P164 during (was time-span of)
Domain: E93 Presence
Range: E52 Time-Span

Subproperty of:   E92 Spacetime Volume.P160 has temporal projection: E52 Time-Span
Quantification:     (1,1 :0,n)
 
Scope note:                 This property relates an instance of E93 Presence with the chosen instance of E52 Time-Span that defines the time-slice of the spacetime volume that this instance of E93 Presence is related to by the property P166 was a presence of (had presence).

The chosen instance of E52 Time-Span may be declared as a particular date range of interest for a documentalist, using the property P170 defines time (time is defined by). Alternatively, a time-span of different empirical origin may be referred to, such as the time-span of some instance of E2 Temporal Entity . The latter construct can be used to specify the whereabouts of some item having the nature of a spacetime volume within the temporal limits of the respective phenomenon. For instance, for describing the whereabouts of some person during a particular war period.
