Dear all,
In the last SIG, the issue of the accuracy of the FOL representation of
P170 defines time (time is defined by) was raised in issue 508
<http://www.cidoc-crm.org/Issue/ID-508-fol-for-p170>. A better FOL
representation was sought for. MD was assigned the HW.
The previous state was:
P170 defines time (time is defined by)
Domain: E61Time Primitive
Range: E52 Time Span
Quantification: many to one (0,1:0,n )
Scope note: This property associates an instance of E61 Time
Primitive with the instance of E52 Time-Span that constitutes the
interpretation of the terms of the time primitive as an extent in absolute,
real time.
Examples:
▪ (1800/1/1 0:00:00 – 1899/31/12 23:59:59)(E61) defines time The
19th century (E52)
▪ (1968/1/1 – 2018/1/1)(E61) defines time “1968/1/1 – 2018/1/1”
(E52) [an arbitrary time-span during which the Saint Titus reliquary was
present in the Saint Titus Church in Heraklion, Crete]
In First Order Logic:
P170(x,y) ⇒ E61(x)
P170(x,y) ⇒ E52(y)
It is proposed to introduce:
P170(x,y) ⇒ P81(y,x) ˄ P82(y,x)
Meaning: the respective time-span is exactly ongoing and within the given
time primitive.
Please vote on this change. Options: Yes, Yes with Caveat, No with
Explanation, to this list.
The vote should be received by Oct 16, 2020.
Thank you for your effort.
Sincerely,
George Bruseker
Vice Chair CIDOC CRM SIG
