Application module: Textual expression representation | ISO/CD-TS 10303-1367 |
This clause specifies the information requirements for the Textual expression representation 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 Textual_expression_representation_arm schema and identifies the necessary external references.
EXPRESS specification:
*)
SCHEMA Textual_expression_representation_arm;
(*
The following EXPRESS interface statements specify the elements imported from the ARMs of other application modules.

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.
EXPRESS specification:
*)
TYPE
list_of_text_based_item =
LIST[1:?] OF Textual_expression_representation_item;
END_TYPE;
(*
The list_or_set_of_text_based_item type allows for the designation of the data types list_of_text_based_item and set_of_text_based_item.
EXPRESS specification:
*)
TYPE
list_or_set_of_text_based_item =
SELECT
(list_of_text_based_item,
set_of_text_based_item);
END_TYPE;
(*
EXPRESS specification:
*)
TYPE
set_of_text_based_item =
SET[1:?] OF Textual_expression_representation_item;
END_TYPE;
(*
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 allows for the designation of the data types Included_text_based_representation, Textual_expression_composition and Textual_expression_representation_item.
EXPRESS specification:
*)
TYPE
text_based_item_select =
SELECT
(Included_text_based_representation,
Textual_expression_composition,
Textual_expression_representation_item);
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.
EXPRESS specification:
*)
ENTITY Included_text_based_representation
SUBTYPE OF (Representation_item);
source : Text_based_representation;
END_ENTITY;
(*
Attribute definitions:
source: the representation that is to be included
NOTE The text is typically written using a formal language.
EXPRESS specification:
*)
ENTITY Text_based_representation
SUBTYPE OF (Representation);
SELF\Representation.context_of_items : Text_based_representation_context;
SELF\Representation.items : SET[1:1] OF text_based_item_select;
END_ENTITY;
(*
Attribute definitions:
context_of_items: the context for the items in the representation
items: the items in the representation
NOTE The text is typically written using a formal language.
EXPRESS specification:
*)
ENTITY Text_based_representation_context
SUBTYPE OF (Representation_context);
END_ENTITY;
(*
EXPRESS specification:
*)
ENTITY Textual_expression_composition
SUBTYPE OF (Representation_item);
content : list_or_set_of_text_based_item;
