On first reading this seems both precise but also very useful generally. I will read again over the weekend.

Dear All,

Here the scope note for E18:

E18 Physical Thing
Subclass of:         E72 Legal Object
Superclass of:     E19 Physical Object
E24 Physical Man-Made Thing
E26 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 has condition (is condition of): E3 Condition State
P45 consists of (is incorporated in): E57 Material
P46 is composed of (forms part of): E18 Physical Thing
P49 has former or current keeper (is former or current keeper of): E39 Actor
P50 has current keeper (is current keeper of): E39 Actor
P51 has former or current owner (is former or current owner of): E39 Actor
P52 has current owner (is current owner of): E39 Actor
P53 has former or current location (is former or current location of): E53 Place
P58 has section definition (defines section): E46 Section Definition
P59 has section (is located on or within): E53 Place
P128 carries (is carried by): E90 Symbolic Object
P156 occupies: E53 Place
P159 occupied: E92 Spacetime Volume


E18 Physical Thing
Subclass of:         E72 Legal Object
Superclass of:     E19 Physical Object
E24 Physical Man-Made Thing
E26 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 existence it 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.
