4 Information requirements

This clause specifies the information requirements for the Parametric 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.

This clause defines the information requirements to which implementations shall conform using the EXPRESS language as defined in ISO 10303-11. The following begins the Parametric_representation_arm schema and identifies the necessary external references.

EXPRESS specification:

*)
SCHEMA Parametric_representation_arm;
(*

4.1 Required AM ARM

The following EXPRESS interface statement specifies the elements imported from the ARM of another application module.

EXPRESS specification:

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

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

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 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.

4.2.1 Definitional_representation   EXPRESS-GMapping table

A Definitional_representation is a type of Representation relating the items that describe the conditions for the parametric representation.

EXPRESS specification:

*)
ENTITY Definitional_representation
  SUBTYPE OF (Representation);
  SELF\Representation.context_of_items : Parametric_representation_context;
END_ENTITY;
(*

Attribute definitions:

context_of_items: an inherited attribute shall be of type Parametric_representation_context for the Definitional_representation.

4.2.2 Parametric_representation_context   EXPRESS-GMapping table

A Parametric_representation_context is a type of Representation_context. A parametric representation context describes the circumstances that enable the parametric representation to be understood.

EXPRESS specification:

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