I am with George on this.

The fact that substantial things have a 1:1 relationship with an STV does not 
warrant the E92 superclass status IMHO. 

It makes for horrible confusion and lots of “special case” rules and ………….

Please let us avoid this.

and E92

 

Dear all,

 

To wade into the muddy waters, I would venture that having E92 as superclass of 
E4 and E18 is finally something that may just create confusion. It is not 
actually the case that a thing IS its space time volume. A thing necessarily 
HAS a STV so long as it is substantial, but the things we say about the STV of 
a thing and what we say about the thing itself are distinct. The convenience we 
get from making E92 the super class of E18 and E4 seems to come at the price of 
this confusion, and the ability to put temporality on physical things directly, 
something we have tried to avoid. If we do however remain committed to it 
having this superclass status, then it seems we should have to put in some 
instructions on how you are able and not able to use the properties that it 
lends downwards to its children classes.

 

Best,

 

George

Dear Robert,

 

In the first place, E2 has a substance of "phenomena" something "becoming" 
"changing" "moving", "interacting". In addition, we interpret it now also more 
statically as including a sort of maintaining something. It is necessarily 
connected to some "things" on which such interactions, changes or temporary, 
non-essential formation of properties happen, but we have seen so far no good 
general way to describe the ways of involvement at the level of E2.

 

E92 is nothing of that kind. It is just spacetime, the generalized space in 
which we live and think, not what is there not what happens there. It is just a 
"where". It is further a volume in that space, i.e., it must have some inner 
part, and a surface as fuzzy as it may be, and a way to identify it.

 

We connect E4 and E18 with E92 as second superclass in order to describe a 
necessary one-to-one combination, in order to save the trivial links between 
them. We could do that with E2 too, but the space in which things like "being 
married" occur can hardly be seen as volumes with a surface. In contrast, I can 
be in the meeting (E4) or outside, in the battle or outside, even though the 
fuzziness between being inside and outside is very high.

 

Therefore, I would exclude both, E2 being subclass of E92 or superclass.

 

The discussion to which degree we should regard any E18 as ongoing interactions 
in spacetime is old and endless. We have so far rather preferred to think of a 
fundamental difference between "becoming" and "being" as a psychological and 
linguistic phenomenon, because this is the most adequate to the way people 
document things. The problem now is that by introducing E92 we are again 
confronted with the borderlines between the change itself and the changing 
thing, the thing that persists over time, but yet is limited in time, the 
things that are somewhere, but constitute a "where" for others.

 

Would that make sense:-)?

 

Best,

 

Martin

Hi all,

 

I’m sure there’s a good reason why this is not a good idea, and if I had been 
at the meetings since the early days I surely would know why it’s not a good 
idea … but …

 

Could E92 not be a sub class of E2, if we were to separate out E3 Condition 
State in the work to model States / Phases more thoroughly?

Then P160 could just be deprecated in favor of P4?  P10, P132 and P133 are all 
still valuable, as they include the intersection of space as well as of time.

 

My first thought was that the properties of E2 other than P4 are not applicable 
to E18 (and descendants) … but if P160 is, and P132/P133 are, then there must 
be some temporality that can have a start and end, as given in the temporal 
projection.   The temporal projection of Rob starts after the start of the 
temporal projection of Rob’s mother seems like a reasonable thing to assert, if 
we can have timespans/temporal projections.

Subject: [Crm-sig] Issue 326 Resolving inconsistencies between E2, E4, E52 and 
E92

 

Dear All,

We consider the following properties:

P4 has time-span (is time-span of)
Domain:               <x-msg://34/#_E2_Temporal_Entity> E2 Temporal Entity
Range:                 <x-msg://34/#_E52_Time-Span> E52 Time-Span
Quantification:    many to one, necessary, dependent (1,1:1,n)

P160  has temporal projection (is temporal projection of)
Domain:  <x-msg://34/#_E92_Spacetime_Volume> E92 Spacetime Volume 
Range:  <x-msg://34/#_E52_Time-Span> E52 Time-Span
Quantification: one to one (1,1:1,1)


In FOL:




P4(x,y) ⊃ E2(x), P4(x,y) ⊃ E52(y)

P160(x,y) ⊃ E92(x), P160(x,y)⊃ E52(y)

The problem comes from this: E4 Period being a spacetime volume and a temporal 
entity.

E4(x) ⊃ E2(x), E4(x) ⊃ E92(x)

I now propose to: declare P4, to imply P160  from E4 Period "downwards":

(P4(x,y) ∧E4(x)) ⊃ P160(x,y), (P160(x,y) ∧E4(x)) ⊃ P4(x,y).

We may then recommend to use only P4 from E4 Period downwards.

I do not know, if we would also need (P160(x,y) ∧E4(x)) ⊃ P4(x,y) in order to 
make them identical from E4 downwards.

================================================

Further:

P7 took place at (witnessed)
Domain:               <x-msg://34/#_E4_Period> E4 Period
Range:                 <x-msg://34/#_E53_Place> E53 Place

Quantification:    many to many, necessary (1,n:0,n)

"The related E53 Place should be seen as a wider approximation of the geometric 
area within which the phenomena that characterize the period in question 
occurred, see below."


P161 has spatial projection (is spatial projection of)
Domain:  <x-msg://34/#_E92_Spacetime_Volume> E92 Spacetime Volume 
Range:  <x-msg://34/#_E53_Place> E53 Place
Superproperty of:  <x-msg://34/#_E18_Physical_Thing> E18 Physical Thing.  
<x-msg://34/#_P153_assigned_co-reference> P156 occupies (is occupied by):  
<x-msg://34/#_E53_Place> E53 Place
Quantification: one to many, necessary, dependent (1,n:1,1) 

Firstly, I believe the quantification of P161 must be Quantification:    many 
to many, necessary (1,n:0,n). A place needs not be the projection of a 
Spacetime Volume.

Then, in FOL:

P7(x,y) ⊃ E4(x), P7(x,y) ⊃ E53(y)

P161(x,y) ⊃ E92(x), P161(x,y) ⊃ E53(y)

I propose to add: The spatial projection of an E4 Period is a "took place at".

(P161(x,y) ∧E4(x)) ⊃ P7(x,y).

Opinions? 

Best,

Martin
