4 Information requirements

This clause specifies the information requirements for the Extended measure 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 Extended_measure_representation_arm schema and identifies the necessary external references.

EXPRESS specification:

*)
SCHEMA Extended_measure_representation_arm;

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 Measure_item_with_precision   EXPRESS-GMapping table

A Measure_item_with_precision is a type of Measure_item that has a precision defined as the number of digits that are significant.

EXPRESS specification:

*)
ENTITY Measure_item_with_precision
  SUBTYPE OF (Measure_item);
  significant_digits : INTEGER;
END_ENTITY;
(*

Attribute definitions:

significant_digits: the number of digits that are significant.

END_ENTITY;
(*

Attribute definitions:

value_determination: the method by which the value has been determined. The value of this attribute need not be specified. Where applicable the following values shall be used:

qualifier: the qualification that applies to the representation of the property value. The value of this attribute need not be specified. Where applicable the following values shall be used:

4.3.3 Value_limit   EXPRESS-GMapping table

A Value_limit is a type of Measure_item that specifies a qualified numerical value representing either the lower limit or the upper limit of a particular quantifiable characteristic.

EXPRESS specification:

*)
ENTITY Value_limit
  SUBTYPE OF (Measure_item);
  limit_qualifier : limit_qualifier_list;
  limit : Value_with_unit;
END_ENTITY;
(*

Attribute definitions:

limit: the qualified quantity value.

4.3.4 Value_limit_with_global_unit   EXPRESS-GMapping table

A Value_limit_with_global_unit is a type of Measure_item that specifies a qualified numerical value representing either the lower limit or the upper limit of a particular quantifiable characteristic and for which the value unit is globally assigned.

EXPRESS specification:

*)
ENTITY Value_limit_with_global_unit
  SUBTYPE OF (Measure_item);
  limit : Numerical_item_with_global_unit;
  limit_qualifier : limit_qualifier_list;
END_ENTITY;
(*

Attribute definitions:

limit: the qualified quantity value.

limit_qualifier: the kind of limit.

4.3.5 Value_list   EXPRESS-GMapping table

A Value_list is a type of Measure_item that is an ordered collection of Measure_items.

EXAMPLE    A Measure_item may be composed of different values such as 'mass', 'speed', and 'age' which are all necessary in a given context. The Value_list collects all of them in a given order, such that each is identifiable by its index in the list.

EXPRESS specification:

*)
ENTITY Value_list
