In version 4.2.3 it is declared that:
| P56 bears feature (is found on): | |
| Domain: | E19 Physical Object |
| Range: | E26 Physical Feature |
| Quantification: | one to many, dependent (0,n:1,1) |
In issue #8, we discussed physical feature decomposition
Do physical feature and its decomposition need to be more rigidly defined?
Background; Do physical feature and its decompositon need to be more rigidly defined?
Old Proposal;
Current Proposal; In scope, done.
Outcome; In version 3.0, the property:
E19 Physical Object. is composed of (forms part of): Physical Object
has been redirected to:
E18 Physical Stuff. is composed of (forms part of): Physical Stuff In order to include "E26 Physical Feature".

It seems that this change we did in issue #8 should imply a subproperty relationship. So the proposal is:
| P56 bears feature (is found on) | |
| Domain: | E19 Physical Object |
| Range: | E26 Physical Feature |
to be subproperty of
| P46 is composed of (forms part of) | |
| Domain: | E18 Physical Thing |
| Range: | E18 Physical Thing |
| Quantification: | many to many (0,n:0,n) |

It is accepted to be P56 isA P46. We should change the scope note of P46 to generalize the notion of components
Nuremberg 4-7 December 2007
New scope note:
P46 is composed of (forms part of)
This property allows instances of E18 Physical Thing to be analysed into component elements.
Component elements, since they are themselves instances of E18 Physical Thing, may be further analysed into sub-components, thereby creating a hierarchy of part decomposition. An instance of E18 Physical Thing may be shared between multiple wholes, for example two buildings may share a common wall.
This property is intended to describe specific components that are individually documented, rather than general aspects. Overall descriptions of the structure of an instance of E18 Physical Thing are captured by the P3 has note property.
The instances of E57 Materials of which an item of E18 Physical Thing is composed should be documented using P45 consists of (is incorporated in).
