Dear All,
Here my rework.
Old scope note:
S22 Segment of Matter//
Subclass of: S20 <#_S20_Physical_Feature>Physical Feature
Scope Note:This class comprises physical features in a relative
stability of form within a specific spacetime volume. The spatial extent
of an instance of S22 Segment of Matter is defined by humans usually
because the geometric arrangement of physical features or parts of them
on or within it are of interest. An instance of S22 Segment of Matter
exists as long as there is no modification of the geometric arrangement
of its parts. Therefore the temporal boundaries of the defining
spacetime volume are given by two S18 Alteration events. It comes into
existence as being an object of discourse through an instance of S4
Observation or declaration and is restricted to the time span starting
after the last change caused by an instance of S18 Alteration before the
observation or declaration and ending with an instance of another S18
Alteration Event.
The history of a S22 Segment of Matter started with a S17 Physical
Genesis event that deposited still existing matter within the defined
spatial extent. The collection of all S18 Alteration events represent
its history. Some of the events will not leave any physical material
within the S22 Segment of Matter.
In other words, this is a fiat object (B. Smith sense) that has
declarative boundaries in 3 dimensions but natural boundaries in time
(the 4^th dimension).
NEW SCOPE NOTE:
S22 Segment of Matter//
Subclass of: S20 <#_S20_Physical_Feature>Physical Feature
Scope Note:This class comprises physical features with relative
stability of form and structure within a declared spatial volume of
interest. The spatial extend of an instance of S22 Segment of Matter may
be declared defined by a researcher or observer usually because the
arrangement and composition of substance is characteristic for the
surrounding matter or can be interpreted as traces of its genesis and
subsequent internal and external processes it was exposed to. The
defining spatial extend is typically declared on a continuous matter by
means of geometric determination without observable boundaries on all
sides or any side. It may however be extracted at some point in time
along the declared boundaries.
An instance of S22 Segment of Matter is regarded to be existing from the
time on it completely consolidated in a solid form and structure that
still preserved in a recognizable way at the time of spatial definition.
Its existence is regarded to end when its respective integrity is
partially or completely corrupted. Uncorrupted subsections of an
instance of S22 Segment of Matter may continue to exist as segments of
matter in their own right beyond the existence of the containing
instance, and may have consolidated before it.
Typical examples are segments of archaeological or geological layers.
They are regarded as uncorrupted even if they have undergone conformal
deformations, such as compressions or shifts, as long as the effects of
these deformations do not destroy the relevant structures of interest.
This means that the defining spatial volume may be only geometrically
valid for an instant of time for which it was declared, and undergo
before and after deformations. In some cases it may be possible to
calculate the initial volume at consolidation time, for instance for
petrified bones compressed in Jurassic layers.
