Application module: Characteristic | ISO/TS 10303-1654:2018-11(E) © ISO |
This clause specifies the EXPRESS schema derived from the mapping table. It uses elements from the common resources or from other application modules and defines the EXPRESS constructs that are specific to this part of ISO 10303.
This clause constitutes the Module Interpreted Module (MIM) of the application module.
This clause also specifies the modifications that apply to the constructs imported from the common resources.
The following restrictions apply to the use, in this schema, of constructs defined in common resources or in application modules:
Short names of entities defined in this schema are described in Annex A. Unambiguous identification of this schema is defined in Annex B.

This subclause specifies the MIM type for this application module. The MIM type and definition is specified below.
The c_document_reference_item type is an extension of the document_reference_item type. It adds the data type representation to the list of alternate data types.

Formal propositions:
WR1: The item_element inherited from compound_representation_item shall be of type row_representation_item.
This subclause specifies the MIM subtype constraint for this module. The subtype constraint places a constraint on the possible super-type / subtype instantiations. The MIM subtype constraint and definition is specified below.
