Application module: Classification | ISO/TS 10303-1212:2005(E) © ISO |
This clause specifies the information requirements for the Classification application module. The information requirements are specified as the Application Reference Model (ARM) of this application module.
NOTE 1 A graphical representation of the information requirements is given in Annex C.
NOTE 2 The mapping specification is specified in 5.1. It shows how the information requirements are met by using common resources and constructs defined or imported in the MIM schema of this application module.
The following EXPRESS specification begins the Classification_arm schema and identifies the necessary external references.

NOTE 2 See Annex C, Figures C.1and C.2 for a graphical representation of this schema.
This subclause specifies the ARM types for this application module. The ARM types and definitions are specified below.
A classifiication_select is a thing that is classified.
EXPRESS specification:
*)
TYPE
classification_select =
EXTENSIBLE
SELECT;
END_TYPE;
(*
A complete_membership_select is a thing that is specified to be one of the members of an explicitly enumerated set.
EXPRESS specification:
*)
TYPE
complete_membership_select =
EXTENSIBLE
SELECT;
END_TYPE;
(*
This subclause specifies the ARM entities for this module. Each ARM application entity is an atomic element that embodies a unique application concept and contains attributes specifying the data elements of the entity. The ARM entities and definitions are specified below.
A classification is a relationship between a class and a thing, that indicates the thing is a member of the class.
NOTE The meaning of this entity is identical to the entity classification defined in ISO 15926-2.
EXPRESS specification:
*)
ENTITY Classification;
classified : classification_select;
classifier : Class;
END_ENTITY;
(*
Attribute definitions:
classified: the member of the classifier.
classifier: the class that has the classified as a member.
A complete_membershipis a relationship that is between a class and an enumerated set of things that indicates the class contains each of the things and nothing else.
EXPRESS specification:
*)
ENTITY Complete_membership;
containing_set : Class;
members : SET[0:?] OF complete_membership_select;
END_ENTITY;
(*
Attribute definitions:
containing_set: the class that contains the members and nothing else.
members: the members of the containing_set.
