Dear All,
Here my attempt to harmonize E4 P9-P10-P158 with phenomenal spacetime:
P158 new:
P158 occupied
Domain: E4 <#_E4_Period> Period
Range: E92 <#_E92_Spacetime_Volume> Spacetime Volume
Quantification: many to one, necessary (1,n:0,n)
Scope note:This property associates an instance of E4 Period with the
real (phenomenal) 4 dimensional point set (volumes) in spacetime that it
has occupied. The associated instance of E92 Spacetime Volume includes
the trajectories of the participating physical things during their
participation in the instance of E4 Period, the open spaces via which
they have interacted and the spaces by which they had the potential to
interact during that period or event in the way defined by the type of
the respective period or event, such as the air in a meeting room
transferring the voices. Another example are the areas controlled by
some military power. In case of phenomena spreading out over islands or
other separated areas, the trajectories necessary for participants to
travel between these areas are not regarded as part of the occupied
spacetime volumes. Such instances of E4 Period occupy each a limited
number of disjoint spacetime volumes, however there must not be a
discontinuity in the total timespan covered by these spacetime volumes.
The real spacetime volumes occupied by an instance of E4 Period must not
be confused with declarations of spacetime approximating the real
extent. In general, instances of E4 Period have fuzzy boundaries in
spacetime.
Therefore it cannot be verified, if two different instances of E4 Period
occupy exactly the same spacetime volume. We therefore determine that a
spacetime volume may only be occupied by one instance of E4 Period.
In case we add the last two phrases, the quantification is (1,n:0,1).
P9 old:
P9 consists of (forms part of)
Domain:E4 <#_E4_Period> Period
Range:E4 <#_E4_Period> Period
Quantification:one to many, (0,n:0,1)
Scope note:This property describes the decomposition of an instance of
E4 Period into discrete, subsidiary periods.
The sub-periods into which the period is decomposed form a logical whole
- although the entire picture may not be completely known - and the
sub-periods are constitutive of the general period.
Examples:
§Cretan Bronze Age (E4) /consists of /Middle Minoan (E4)
P9 new scope note:
Scope note:This property associates an instance of E4 Period with
another instance of E4 Period that falls within the
spacetime volumes occupied by the former
and which is defined by phenomena that form part or refinements
of the phenomena that define the former.
P10 old:
P10 falls within (contains)
Domain:E4 <#_E4_Period> Period
Range:E4 <#_E4_Period> Period
Quantification:many to many (0,n:0,n)
Scope note:This property describes an instance of E4 Period, which falls
within the E53 Place and E52 Time-Span of another.
The difference with /P9 consists of (forms part of)/ is subtle. Unlike
/P9 consists of (forms part of)/, /P10 falls within/ /(contains)/ does
not imply any logical connection between the two periods and it may
refer to a period of a completely different type.
Examples:
§the Great Plague (E4) /falls within/ The Gothic period (E4)
P10 new scope note:
Scope note:This property describes an instance of E4 Period, which
occupies spacetime volumes that are complete covered by the extent of
the spacetime volumes occupied by the associated instance of E4 Period.
The difference with /P9 consists of (forms part of)/ is subtle. Unlike
/P9 consists of (forms part of)/, /P10 falls within/ /(contains)/ does
not imply any logical connection between the two periods and it may
refer to a period of a completely different type.
E4 old scope note:
E4 Period
Subclass of:E2 <#_E2_Temporal_Entity> Temporal Entity
Superclass of: E5 <#_E5_Event> Event
Scope note:This class comprises sets of coherent phenomena or cultural
manifestations bounded in time and space.
It is the social or physical coherence of these phenomena that identify
an E4 Period and not the associated spatio-temporal bounds. These bounds
are a mere approximation of the actual process of growth, spread and
retreat. Consequently, different periods can overlap and coexist in time
and space, such as when a nomadic culture exists in the same area as a
sedentary culture.
Typically this class is used to describe prehistoric or historic periods
such as the "Neolithic Period", the "Ming Dynasty" or the "McCarthy
Era". There are however no assumptions about the scale of the associated
phenomena. In particular all events are seen as synthetic processes
consisting of coherent phenomena. Therefore E4 Period is a superclass of
E5 Event. For example, a modern clinical E67 Birth can be seen as both
an atomic E5 Event and as an E4 Period that consists of multiple
activities performed by multiple instances of E39 Actor.
There are two different conceptualisations of 'artistic style', defined
either by physical features or by historical context. For example,
"Impressionism" can be viewed as a period lasting from approximately
1870 to 1905 during which paintings with particular characteristics were
produced by a group of artists that included (among others) Monet,
Renoir, Pissarro, Sisley and Degas. Alternatively, it can be regarded as
a style applicable to all paintings sharing the characteristics of the
works produced by the Impressionist painters, regardless of historical
context. The first interpretation is an E4 Period, and the second
defines morphological object types that fall under E55 Type.
Another specific case of an E4 Period is the set of activities and
phenomena associated with a settlement, such as the populated period of
Nineveh.

As the actual extent of an E4 Period in spacetimewe regard the
trajectories of the participating physical things during their
participation in the instance of E4 Period, the open spaces via which
they have interacted and the spaces by which they had the potential to
interact during that period or event in the way defined by the type of
the respective period or event, such as the air in a meeting room
transferring the voices. Since these phenomena are fuzzy, we assume the
spatiotemporal extent to be contiguous, except for cases of phenomena
spreading out over islands or other separated areas. In these cases, the
trajectories necessary for participants to travel between these areas
are not regarded as part of the spatiotemporal extent. Consequently,
instances of E4 Period may occupy each a limited number of disjoint

P159:
P159 occupied
Domain: E18 <#_E18_Physical_Thing> Physical Thing
Range: E92 <#_E92_Spacetime_Volume> Spacetime Volume
Quantification: many to one, necessary (1,n:0,n)
Scope note:This property describes the real (phenomenal) 4 dimensional
point sets (volumes) in spacetime that the trajectory of an instance of
E18 Physical Thing occupies in spacetime in the course of its existence.
We include in the occupied space the space filled by the matter of the
physical thing and all its inner spaces.
I add: "Physical things consisting of aggregations of physically
unconnected object s, such as a set of chessmen, occupy a number of
spacetime volumes corresponding to the number of unconnected objects
that constitute them."
To be discussed.
Best,
Martin
