4 Information requirements

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;
(*

4.1 Required AM ARMs

The following EXPRESS interface statements specify the elements imported from the ARMs of other application modules.

EXPRESS specification:

*)
USE FROM Classification_assignment_arm;    --  ISO/TS 10303-1114

USE FROM Foundation_representation_arm;    --  ISO/TS 10303-1006
(*

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

Classification_assignment_arm ISO/TS 10303-1114
Foundation_representation_arm ISO/TS 10303-1006

NOTE 2   See Annex C, Figures C.1and C.2 for a graphical representation of this schema.

4.2 ARM type definitions

This subclause specifies the ARM types for this application module. The ARM types and definitions are specified below.

4.2.1 list_of_text_based_item   EXPRESS-G

A list of representation items written using text.

EXPRESS specification:

*)
TYPE list_of_text_based_item = LIST[1:?] OF Textual_expression_representation_item;
END_TYPE;
(*

4.2.2 list_or_set_of_text_based_item   EXPRESS-G

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;
(*

4.2.3 set_of_text_based_item   EXPRESS-G

A set of representation items written using text.

EXPRESS specification:

*)
TYPE set_of_text_based_item = SET[1:?] OF Textual_expression_representation_item;
END_TYPE;
(*

4.2.4 ter_classification_item   EXPRESS-G

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;
(*

4.2.5 text_based_item_select   EXPRESS-G

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;
(*

4.3 ARM entity definitions

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.

4.3.1 Included_text_based_representation   EXPRESS-GMapping table

A Included_text_based_representation is a type of Representation_item where one Text_based_representation is included as a constituent of a Representation_item.

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

4.3.2 Text_based_representation   EXPRESS-GMapping table

A Text_based_representation is a type of Representation where the representation is written using text.

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

4.3.3 Text_based_representation_context   EXPRESS-GMapping table

A Text_based_representation_context is a type of Representation_context where the representations are text-based.

NOTE    The text is typically written using a formal language.

EXPRESS specification:

*)
ENTITY Text_based_representation_context
  SUBTYPE OF (Representation_context);
END_ENTITY;
(*

4.3.4 Textual_expression_composition   EXPRESS-GMapping table

A Textual_expression_composition is a type of Representation_item where that is made up of constituent Textual_expression_representation_item's.

EXPRESS specification:

*)
ENTITY Textual_expression_composition
  SUBTYPE OF (Representation_item);
  content : list_or_set_of_text_based_item;
END_ENTITY;
(*

Attribute definitions:

content: the items to be included in the composition

4.3.5 Textual_expression_representation_item   EXPRESS-GMapping table

A Textual_expression_representation_item is a type of String_representation_item that is written using text.

EXPRESS specification:

*)
ENTITY Textual_expression_representation_item
  SUBTYPE OF (String_representation_item);
END_ENTITY;
(*



*)
