5.2 MIM EXPRESS short listing

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:

• use of a supertype entity does not make applicable any of its specializations, unless the specialization is also imported in the MIM schema;
• use of a SELECT type does not make applicable any of its listed types unless the listed type is also imported in the MIM schema.

Short names of entities defined in this schema are described in Annex A. Unambiguous identification of this schema is defined in Annex B.

USE FROM Component_grouping_mim;    --  ISO/TS 10303-1656



USE FROM Assembly_shape_mim;    --  ISO/TS 10303-1808

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

Component_grouping_mim	ISO/TS 10303-1656
Assembly_shape_mim	ISO/TS 10303-1808

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

5.2.1 MIM entity definitions

This subclause specifies the MIM entities for this module. The MIM entities and definitions are specified below.

5.2.1.1 assembly_component   

EXPRESS specification:

*)
ENTITY assembly_component
  SUBTYPE OF (component_definition, product_definition_shape);
DERIVE
  SELF\property_definition.definition : assembly_component := SELF;
WHERE
  WR1: NOT EXISTS(SELF\property_definition.description);
END_ENTITY;
(*

Attribute definitions:

definition: an attribute inherited from the property_definition shall be redeclared as the assembly_component for the assembly_component.

Formal propositions:

WR1: The description shall not be specified for the assembly_component.

5.2.1.2 component_definition   

A component_definition is a type of product_definition and a type of product_definition_relationship that represents a product that is used in an assembly. The component_definition entity implements the ARM concepts of:

• Array_placement_group;
• Assembly_component;
• Assembly_group_component;
• Assembly_module_component;
• Assembly_module_macro_component;
• Bare_die_component;
• Cable_component;
• Interconnect_module_component;
• Interconnect_module_macro_component;
• Interface_component;
• Physical_component;
• Laminate_component;
• Routed_interconnect_component;
• Routed_physical_component;
• Thermal_component.

EXPRESS specification:

*)
ENTITY component_definition
  SUBTYPE OF (product_definition, product_definition_relationship);
DERIVE
  SELF\product_definition_relationship.related_product_definition : component_definition := SELF;
WHERE
  WR1: NOT EXISTS(SELF\product_definition_relationship.description);
  WR2: NOT EXISTS(SELF\property_definition.description);
  WR3: SELF\product_definition_relationship.id = SELF\product_definition.id;
  WR4: SELF\product_definition_relationship.name = 'definition usage';
  WR5: NOT ('PRODUCT_STRUCTURE_SCHEMA.' + 'PRODUCT_DEFINITION_USAGE' IN TYPEOF(SELF));
END_ENTITY;
(*

Attribute definitions:

related_product_definition: an attribute inherited from the product_definition_relationship shall be redeclared as the component_definition for the component_definition.

Formal propositions:

WR1: The product_definition_relationship.description shall not be specified for the component_definition.

WR2: The property_definition.description shall not be specified for the component_definition.

WR3: The product_definition_relationship.id shall be equal to the product_definition.id.

WR4: The product_definition_relationship.name shall be 'definition usage'.

WR5: The component_definition shall not be a product_definition_usage.

5.2.1.3 physical_component   

EXPRESS specification:

*)
ENTITY physical_component
  SUBTYPE OF (assembly_component);
END_ENTITY;
(*

5.2.1.4 thermal_component   

A thermal_component is a type of assembly_component that implements the ARM concept of Thermal_component.

EXPRESS specification:

*)
ENTITY thermal_component
  SUBTYPE OF (assembly_component);
END_ENTITY;
(*
