Dear All,
Here my revision of P81, P82. I have added the phrases in bold, and
added examples. This should go into version 7.0.
I have kept the quantification many to one, because keeping
simultaneously multiple estimates is aquestion of provenance. If the
maintainers of the KB believe all estimates are correct, they should
replace them by the estimate as described in bold, and document the
arguments for the individual periods. On the other side, if they decide
to keep different time-spans for the same period per estimate, the query
mechanism should compute and evaluate based on the resulting estimate as
described in bold.
Please comment.
Best,
Martin

"P81 ongoing throughout" (at least)
και "P82 at some time within"(at most) :
P81 ongoing throughout
Domain: E52 <#_E52_Time-Span> Time-Span
Range: E61 <#_E61_Time_Primitive> Time Primitive
Quantification: many to one, necessary (1,1:0,n)
Scope note: This property associates an instance of E52
Time-Span with an instance of E61 Time Primitive specifying a minimum
period of time covered by it. Since Time-Spans may not have precisely
known temporal extents, the CIDOC CRM supports statements about the
minimum and maximum temporal extents of Time-Spans. This property
allows a Time-Span’s minimum temporal extent (i.e. its inner boundary)
to be assigned an E61 Time Primitive value. Time Primitives are treated
by the CIDOC CRM as application or system specific date intervals, and
are not further analysed. *If different sources of evidence justify
different minimum extents without contradicting each other, the smallest
interval including these extents will be the best estimate.**This should
be taken into account for information integration.
*
Examples: * The time-span of the development of the CIDOC
CRM(E52) /ongoing throughout/ 1996-2019(E61) (observed until time of
documentation 1.1.2020)
* The time-span of the construction of the
imperial palace in Beijing under Emperor Yong Le(E52) /ongoing
throughout/ 1407-1419 (E61)
P82 at some time within
Domain: E52 <#_E52_Time-Span> Time-Span
Range: E61 <#_E61_Time_Primitive> Time Primitive
Quantification: many to one, necessary (1,1:0,n)
Scope note: This property describes the maximum period of time
within which an E52 Time-Span falls. Since Time-Spans may not have
precisely known temporal extents, the CIDOC CRM supports statements
about the minimum and maximum temporal extents of Time-Spans. This
property allows a Time-Span’s maximum temporal extent (i.e. its outer
boundary) to be assigned an E61 Time Primitive value. Time Primitives
are treated by the CIDOC CRM as application or system specific date
intervals, and are not further analysed. *If different sources of
evidence justify different maximum extents ***without contradicting each
other*, the resulting intersection of these extents will be the best
estimate. **This should be taken into account for information integration.
*
Examples: * The time-span of the development of the CIDOC CRM (E52) /at
some time within/ 1992-infinity (E61)
* The time-span of the Battle of the Teutoburg
Forest (E52) /at some time within 9AD (E61)/
/ * /The time-span of the construction of the
imperial palace in Beijing under Emperor Yong Le (E52) /at some time
within/ 1406-1420(E61)
