Dear All,
Here my proposed scope note:
S20 Rigid Physical Feature//
Subclass of:E26 Physical Feature
E53 <#_E53_Place>Place
Superclass of: E25 <#_E25_Man-Made_Feature_1>Man-Made Feature
E27 <#_E26_Physical_Feature>Site
S22 <#_S22_Segment_of>Segment of Matter //
//
Equivalent to:E26 <#_E26_Physical_Feature_2>*//*Physical Feature (CIDOC-CRM)
Scope Note:This class comprises physical features that are physically
attached in an integral way to particular physical objects and have a
stability of form in themselves and with respect to the physical object
bearing it that is sufficient to associate a permanent reference space
in which its form is invariant and at rest.
Due to this stability of form, the maximal real volume in space that an
instance of S20 Rigid Physical Feature is occupying during its lifetime
with respect to the default reference space relative to which the
feature is at rest defines uniquely a place for the feature with respect
to its surrounding matter.
Therefore we model S20 Rigid Physical Feature as a subclass of E26
Physical Featureand of E53 <#_E53_Place>Place. The latter is intended as
a phenomenal place as defined in CRMgeo (Doerr and Hiebel 2013). By
virtue of this multiple inheritance we can discuss positions relative to
the extent of an instance of S20 Rigid Physical Featurewithout
representing each instance of it together with an instance of its
associated place. This model combines two quite different kinds of
substance: an instance of Since the identity and existence of this place
depends uniquely on the identity of the instance of S20 Rigid Physical
Feature as matter,this multiple inheritance is unambiguous and effective
and furthermore corresponds to the intuitions of natural language. It
shortcuts an implicit self-referential path from E26 Physical Feature
through /P156 occupies,/ E53 Place, /P157 is at rest relative to/ E26
Physical Feature.
In cases of instances of S20 Rigid Physical Feature on or in the surface
of earth, the default reference is typically fixed to the closer
environment of the tectonic plate or sea floor. In cases of features on
mobile objects, the reference space is typically fixed to the geometry
of the bearing object. Note that the reference space associated with the
instance of S20 Rigid Physical Feature may quite well be deformed over
time, as long the continuity of its topology does not become unclear,
such as the compression of dinosaur bones in geological layers, or the
distortions of the hull of a ship by the waves of the sea. Defined in
this way, the reference space can be used as a means to infer from
current topological relationships past topological relationships of
interest.
Examples:
§the temple in Abu Simbel before its removal, which was carved out of
solid rock
§Albrecht Duerer's signature on his painting of Charles the Great
§the damaged nose of the Great Sphinx in Giza
§The bones of the Ichtyosaur in Holzmaden, Germany.
§The “Schliemann cut” in Troy
In First Order Logic:
S20(x) ⊃E26(x)
S20(x) ⊃E53(x)
