Application module: Textual expression representation | ISO/CD-TS 10303-1367 |
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:

NOTE 1 The schemas referenced above are specified in the following part of ISO 10303:

NOTE 2 See Annex D, Figures D.1and D.2 for a graphical representation of this schema.
This subclause specifies the MIM types for this application module. The MIM types and definitions are specified below.
The ter_classification_item type is an extension of the classification_item type. It adds the data types representation_context and text_based_representation to the list of alternate data types.
EXPRESS specification:
*)
TYPE
ter_classification_item =
SELECT
BASED_ON
classification_item
WITH
(representation_context,
text_based_representation);
END_TYPE;
(*
The text_based_item_select type is an extensible list of alternate data types that allows for the designation of the data types included_text_based_representation, textual_expression_composition and textual_expression_representation_item.
NOTE The list of entity data types may be extended in application modules that use the constructs of this module.
EXPRESS specification:
*)
TYPE
text_based_item_select =
EXTENSIBLE
GENERIC_ENTITY
SELECT
(included_text_based_representation,
textual_expression_composition,
textual_expression_representation_item);
END_TYPE;
(*
This subclause specifies the MIM entities for this module. The MIM entities and definitions are specified below.
EXPRESS specification:
*)
ENTITY included_text_based_representation
SUBTYPE OF (representation_item);
END_ENTITY;
(*
EXPRESS specification:
*)
ENTITY text_based_representation
SUBTYPE OF (representation);
SELF\representation.context_of_items : text_based_representation_context;
SELF\representation.items : SET[1:?] OF text_based_item_select;
END_ENTITY;
(*
Attribute definitions:
context_of_items: the text_based_representation_context denoting the circumstances in which an expression is represented using text.
items: the textual_expression_representation_item, included_text_based_representation, or textual_expression_composition objects that compose the text_based_representation.
EXPRESS specification:
