Dear All,
I propose E4 Period and E18 Physical Thing to become subclass
of E92 Space Time Volume, in the sense of the phenomenal spatiotemporal
extent, which is necessaryly one-to-one. This will greatly simplify
dealing with topological relations between things and periods, and
restore consistency that Allen relations are directly attached to the
temporal
entity rather than its time-span.
It does not create any existence-period conflict with E4 or E18.
It further simplifies use of Snapshot to say where things are during some
time-span.
Best,
Martin
