Dear All
As discussed in Berlin, I proposed to deprecate P83, P84, because in
competes with an interval interpretation of P90, and :
Introduce instead Pxxx had duration, Domain: E52 Time-Span, Range: E54
Dimension
and use the P90, P90a, P90b as adequate
or introduce an Exxx Temporal Duration , subclass of E54 Dimension, and
define subproperties in RDFS ending in xsd:duration.
Here my definition:
*Pxxx had duration (was duration of)*
Domain: E52 Time-Span
Range: E54 Dimension
Quantification: one to one (1,1:1,1)
Scope note: This property describes the length of time covered
by an E52 Time-Span. It allows an E52 Time-Span to be associated with an
E54 Dimension representing duration (i.e. it’s inner boundary)
independent from the actual beginning and end. Indeterminacy of the
duration value can be expressed by assigning a numerical interval to the
property P90 has value of E54 Dimension.
Examples:
§ the time span of the Battle of Issos 333 B.C.E. (E52) /had duration/
Battle of Issos minimum duration (E54) has unit (P91) day (E58) has
value (P90) (E60)
In First Order Logic:
Pxxx(x,y) ⊃E52(x)
Pxxx(x,y) ⊃E54(y)

See:
P83 had at least duration (was minimum duration of)
Domain: E52 Time-Span
Range: E54 Dimension
Quantification: one to one (1,1:1,1)
Scope note: This property describes the minimum length of time
covered by an E52 Time-Span.
It allows an E52 Time-Span to be associated with an E54 Dimension
representing it’s minimum duration (i.e. it’s inner boundary)
independent from the actual beginning and end.
Examples:
§ the time span of the Battle of Issos 333 B.C.E. (E52) had at least
duration Battle of Issos minimum duration (E54) has unit (P91) day (E58)
has value (P90) 1 (E60)
In First Order Logic:
P83(x,y) ⊃ E52(x)
P83(x,y) ⊃ E54(y)
P84 had at most duration (was maximum duration of)
Domain: E52 Time-Span
Range: E54 Dimension
Quantification: one to one (1,1:1,1)
Scope note: This property describes the maximum length of time
covered by an E52 Time-Span.
It allows an E52 Time-Span to be associated with an E54 Dimension
representing it’s maximum duration (i.e. it’s outer boundary)
independent from the actual beginning and end.
Examples:
§ the time span of the Battle of Issos 333 B.C.E. (E52) had at most
duration Battle of Issos maximum duration (E54) has unit (P91) day (E58)
has value (P90) 2 (E60)
In First Order Logic:
P84(x,y) ⊃ E52(x)
P84(x,y) ⊃ E54(y)
