Dear All,

Here the scope note for E18:


      E18 Physical Thing

Subclass of:E72 <#_E72_Legal_Object> Legal Object

Superclass of: E19 <#_E19_Physical_Object> Physical Object

E24 <#_E24_Physical_Man-Made_Thing> Physical Man-Made Thing

E26 <#_E26_Physical_Feature> Physical Feature

Scope Note:This class comprises all persistent physical items with a 
relatively stable form, man-made or natural.

Depending on the existence of natural boundaries of such things, the CRM 
distinguishes the instances of E19 Physical Object from instances of E26 
Physical Feature, such as holes, rivers, pieces of land etc. Most 
instances of E19 Physical Object can be moved (if not too heavy), 
whereas features are integral to the surrounding matter.

The CRM is generally not concerned with amounts of matter in fluid or 
gaseous states.

Examples:

§the Cullinan Diamond (E19)

§the cave “Ideon Andron” in Crete (E26)

§the Mona Lisa (E22)

Properties:

P44 <#_P44_has_condition_%28condition%20of%29> has condition (is 
condition of): E3 <#_E3_Condition_State> Condition State

P45 <#_P45_consists_of_%28is%20incorporated%20in> consists of (is 
incorporated in): E57 <#_E57_Material> Material

P46 <#_P46_is_composed_of%20%28forms%20part%20of%29> is composed of 
(forms part of): E18 <#_E18_Physical_Thing> Physical Thing

P49 <#_P49_has_former_or%20current%20keeper%20%28i> has former or 
current keeper (is former or current keeper of): E39 <#_E39_Actor> Actor

P50 <#_P50_has_current_keeper%20%28is%20current%20> has current keeper 
(is current keeper of): E39 <#_E39_Actor> Actor

(defines section): E46 <#_E46_Section_Definition> Section Definition

P59 <#_P59_has_section_%28is%20located%20on%20or%20w> has section (is 
located on or within): E53 <#_E53_Place> Place

P128 <#_P128_carries_%28is_carried%20by%29> carries (is carried by): E90 
<#_E90_Symbolic_Object> Symbolic Object

Volume


      E18 Physical Thing

Subclass of:E72 <#_E72_Legal_Object> Legal Object

Superclass of: E19 <#_E19_Physical_Object> Physical Object

E24 <#_E24_Physical_Man-Made_Thing> Physical Man-Made Thing

E26 <#_E26_Physical_Feature> Physical Feature

Scope Note:This class comprises all persistent physical items with a 
relatively stable form, man-made or natural.

Depending on the existence of natural boundaries of such things, the CRM 
distinguishes the instances of E19 Physical Object from instances of E26 
Physical Feature, such as holes, rivers, pieces of land etc. Most 
instances of E19 Physical Object can be moved (if not too heavy), 
whereas features are integral to the surrounding matter.

An instances of E18 Physical Thing occupies not only a particular 
geometric space, but in the course of its existenceit performs a 
trajectory through spacetime, which occupies a real, that is phenomenal, 
volume in spacetime. We include in the occupied space the space filled 
by the matter of the physical thing and all its inner spaces, such as 
the inner of a box. Physical things consisting of aggregations of 
physically unconnected objects, such as a set of chessmen, occupy a 
number of individually contiguous spacetime volumes equal to the number 
of unconnected objects that constitute them.

Even though the substance of an instance of E18 Physical Thing is matter 
and hence different from the substance of a spacetime volume, which is 
an aggregation of 4 dimensional points in spacetime, the real 
spatiotemporal extent of an instance of E18 Physical Thing is regarded 
to be unique to it due to all its details and fuzziness. Its identity 
and existence depends uniquely on the identity of the instance of E18 
Physical Thing. Therefore we model E18 Physical Thing to be a subclass 
of E72 Legal Object and of E92 Spacetime volume, a “phenomenal” one (see 
Hiebel et al.). By virtue of this multiple inheritance, we avoid 
representing each instance of E18 Physical Thing together with an 
instance of its associated spacetime volume, if we want to talk about 
the places it occupies through time. This model, even though combining 
two distinct kinds of substance, is unambiguous, effective and 
corresponds to the intuitions of natural language.

The CRM is generally not concerned with amounts of matter in fluid or 
gaseous states.
