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.

EXPRESS specification:




         *)

            SCHEMA Extended_measure_representation_mim;

USE FROM Qualified_measure_mim; -- ISO/TS 10303-1782

USE FROM representation_schema -- ISO 10303-43 (compound_item_definition, compound_representation_item, list_representation_item, set_representation_item);

REFERENCE FROM support_resource_schema -- ISO 10303-41 (type_check_function); (*

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

Qualified_measure_mim ISO/TS 10303-1782

representation_schema ISO 10303-43

support_resource_schema ISO 10303-41

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

5.2.1 MIM entity definition

This subclause specifies the MIM entity for this module. The MIM entity and definition is specified below.

5.2.1.1 value_range

A value_range is a type of compound_representation_item that implements the ARM concept of Value_range. A value_range specifies a range of values defined either by two instances of measure_representation_item or of value_representation_item.

EXPRESS specification:

*) ENTITY value_range SUBTYPE OF (compound_representation_item); WHERE WR1: ( 'REPRESENTATION_SCHEMA.'+ 'SET_REPRESENTATION_ITEM' IN TYPEOF ( item_element ) ) AND value_range_wr1 ( item_element ); WR2: value_range_wr2 ( item_element ); WR3: value_range_wr3 ( item_element ); END_ENTITY; (*

Formal propositions:

WR1: The value_range shall have a set_representation_item as its item_element. This set_representation_item shall contain exactly two items of the same type in its set. These items shall be either instances of measure_representation_item or of value_representation_item.

WR2: One of the representation_items in the set specified by item_element shall have a name of 'upper limit', and the other a name of 'lower limit'.

WR3: If the set specified by item_element consists of measure_representation_items, then these shall point to the same instance of named_unit or derived_unit as their respective unit_component.

5.2.2 MIM function definitions

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

5.2.2.1 value_range_wr1

The value_range_wr1 function accepts an AGGREGATE of representation_item and returns a boolean result. The function will return TRUE if the AGGREGATE contains either exactly two measure_representation_items or two value_representation_items. Else it will return FALSE.

NOTE This function realizes the first local rule of value_range.

EXPRESS specification:


         *)

         FUNCTION value_range_wr1 (agg : compound_item_definition) : BOOLEAN;

BEGIN
      IF (SIZEOF(agg) = 2) AND ((SIZEOF(QUERY (i1 <* agg | (
        'QUALIFIED_MEASURE_SCHEMA.MEASURE_REPRESENTATION_ITEM' IN TYPEOF
        (i1)))) = 2) OR
        (SIZEOF(QUERY (i2 <* agg | (
        'REPRESENTATION_SCHEMA.VALUE_REPRESENTATION_ITEM' IN TYPEOF
        (i2)))) = 2)) 
      THEN
        RETURN(TRUE);
      ELSE
        RETURN(FALSE);
      END_IF;
    END;


         END_FUNCTION;
         
(*

Argument definitions:

agg: the AGGREGATE of representation_items which are tested.

5.2.2.2 value_range_wr2

The value_range_wr2 function accepts an AGGREGATE of representation_item and returns a boolean result. The function will return TRUE if the AGGREGATE contains two representation_items that have a name of 'upper limit' and 'lower limit'. Else it will return FALSE.

NOTE This function realizes the second local rule of value_range.

EXPRESS specification:


         *)

         FUNCTION value_range_wr2 (agg : compound_item_definition) : BOOLEAN;

BEGIN
      IF ((SIZEOF(QUERY (i <* agg | (i\representation_item.name = 'upper limit'))) = 1)
        AND (SIZEOF(QUERY (i <* agg | (i\representation_item.name = 'lower limit'))) = 1))
      THEN
        RETURN(TRUE);
      ELSE
        RETURN(FALSE);
      END_IF;
    END;


         END_FUNCTION;
         
(*

Argument definitions:

agg: the AGGREGATE of representation_items which are tested.

5.2.2.3 value_range_wr3

The value_range_wr3 function accepts an AGGREGATE of representation_item and returns a boolean result. The function will return TRUE if the AGGREGATE contains two measure_representation_items that reference the same unit_component. Else it will return FALSE.

NOTE This function realizes the third local rule of value_range.

EXPRESS specification:


         *)

         FUNCTION value_range_wr3 (agg : compound_item_definition) : BOOLEAN;

BEGIN
      IF (SIZEOF(QUERY(i1 <* agg |
        ('QUALIFIED_MEASURE_SCHEMA.MEASURE_REPRESENTATION_ITEM' IN TYPEOF (i1)) AND
        (SIZEOF (QUERY (i2 <* agg |
        ('QUALIFIED_MEASURE_SCHEMA.MEASURE_REPRESENTATION_ITEM' IN TYPEOF (i2)) AND
        (i1 :<>: i2) AND (i1\measure_with_unit.unit_component :=: i2\measure_with_unit.unit_component))) = 1))) = 2)
      THEN
        RETURN (TRUE);
      ELSE
        RETURN (FALSE);
      END_IF;
    END;


         END_FUNCTION;
         
(*

Argument definitions:

agg: the AGGREGATE of representation_items which are tested.

5.2.3 MIM rule definition

This subclause specifies the MIM rule for this module. The MIM rule and definition is specified below.

5.2.3.1 subtype_exclusiveness_representation_item

The subtype_exclusiveness_representation_item rule specifies that certain subtypes of representation_item are mutually exclusive.

EXPRESS specification:


         *)

         RULE subtype_exclusiveness_representation_item FOR
         

         
         (representation_item);

WHERE
 
           WR1: SIZEOF(QUERY (cri <* representation_item | 
         NOT (type_check_function(cri,['QUALIFIED_MEASURE_SCHEMA.MEASURE_REPRESENTATION_ITEM',
         'REPRESENTATION_SCHEMA.VALUE_REPRESENTATION_ITEM',
         'REPRESENTATION_SCHEMA.COMPOUND_REPRESENTATION_ITEM'] , 3)))) = 0;

         END_RULE;
         
(*

Argument definitions:

representation_item : the set of all instances of representation_item.

Formal propositions:

WR1: Each instance of measure_representation_item, value_representation_item or compound_representation_item shall not be simultaneously an instance of these other subtypes of representation_item.
