Dear Franco,
Thank you for your proposal! You are too active!
This is another alternative of a more general proposal of spatiotemporal
restrictions we had discussed in the previous version of CRM 6.2. The
problem is that the restriction of an E92 to a place results in a series
of time-spans, and we were not sure about the semantics of this thing.
We were discussing Chinese invasions in Vietnam as example. We require
an E92 to be contiguous in time. In case we talk about bronze age in
England, one could regard it also as sub-period, which has a total
time-span. The .1 link is equivalent to an intermediate node, so, we'll
discuss your proposal to revive the discussion. If we do not require to
represent the intermediate node as a first-class object, we can bypass
the headache;-) .
All the best,
Martin

Dear Chryssoula and others
it seems that I will unfortunately miss also this SIG meeting. Instead, Paola
and Achille are coming and will report on some interesting thoughts come up at
the Poznan TPDL workshop on the CRM. They are now looking for flights and may
arrive at some time on Tuesday, depending on connections and seat availability.
Thus they may miss the 1st day of the SIG meeting, Tuesday 6th.
There is one small thing coming up during the Poznan discussion which might
concern the discussion on Tuesday, according to the agenda, so I summarize it
below.
E92 Space-time volume is the domain of the two properties P160 has temporal
projection, and P161 has spatial projection. However these two properties link
E92 respectively to an E52 Time-span and to a E53 Place; these are the
*overall* projection of the E92, i.e. throughout any place (P160) and any time
(P161).
Additionally, there exists P164 is restricted by, which generates a new
Space-time volume, actually a subclass E93, restricted to a specific Time-span.
It may be useful to restrict these projections at a specific place (for P160)
and at a specific time (for P161).
So one could consider the utility of defining
P160.1 at E53 Place. It characterizes the temporal projection (a Time-span) of
E92 at a specific Place
P161.1 at E52 Time-span. It characterizes the spatial projection (a Place) of
E92 at (during) a given Time-Span.
Actually the same effect of P161.1 may obtained this way: E92 Space-time
Volume: P164 is restricted by; E52 Time-span: P161 has spatial projection: E53
Place.
So P161.1 is a sort of shortcut, but it complements nicely the proposed P160.1.
Here is a an example: the space-time volume describing the 4D extent of Iron
Age in Europe
P160 -> Which was the time span of Iron Age (answer: from 11th century BC until
circa 1100 AD)
P160.1 -> Which was the time span of Iron Age in England? (answer: from 800 BC
until 43 AD)
P161 -> Where was Iron Age (answer: all Europe)
P161.1 -> Where was Iron Age during the 1st century AD? (answer: the areas not
yet conquered by the Romans at year 1 AD, approximately modern time UK, Germany,
Scandinavia, Eastern Europe; part of these were conquered during the century)
The Pleiades mapping paper, presented at Poznan, has full-fledged scope notes
for the above.
Best wishes
Franco
