Capability EXPRESS information model

This section describes the EXPRESS information model for the capability.

From module : effectivity - using all

Dated_effectivity

• either, the time interval between the start and end date or event;
• or, the open time interval that starts at the start date or event.


ENTITY Dated_effectivity
  SUBTYPE OF (Effectivity);
  start_bound : date_or_event;
  end_bound : OPTIONAL date_or_event;
END_ENTITY;


start_bound: the date or event that defines the lower bound of the interval of applicability.

end_bound: the date or event that defines the upper bound of the interval of applicability. The value of the attribute need not be specified. If the value for this attribute is not specified, the interval of applicability has no upper limit.

Effectivity

NOTE    Instances of Effectivity may be applied to any kind of product or activity data, using the constructs defined in the Effectivity application module.


ENTITY Effectivity
  SUPERTYPE OF (ONEOF (Serial_effectivity,
                       Dated_effectivity,
                       Lot_effectivity,
                       Time_interval_effectivity));
  id : STRING;
  name : STRING;
  description : OPTIONAL STRING;
END_ENTITY;


id: the identifier that distinguishes the Effectivity.

name: the words by which the Effectivity is known.

description: the text that provides further information about the Effectivity. The value of the attribute need not be specified.

Effectivity_relationship


ENTITY Effectivity_relationship;
  relation_type : STRING;
  description : OPTIONAL STRING;
  relating_effectivity : Effectivity;
  related_effectivity : Effectivity;
END_ENTITY;


relation_type:

the text that specifies the meaning of the relationship.

Where applicable, the following value shall be used:

• 'constraint': The domain of the related Effectivity shall be included in the domain of the relating Effectivity.

description: the text that provides further information about the relationship. The value of the attribute need not be specified.

relating_effectivity: the first of the related instances of Effectivity.

related_effectivity: the second of the related instances of Effectivity.

Lot_effectivity


ENTITY Lot_effectivity
  SUBTYPE OF (Effectivity);
  lot_id : STRING;
  lot_size : Value_with_unit;
END_ENTITY;


lot_id: the identification of the batch of items.

lot_size: the size of the batch of items.

Serial_effectivity


ENTITY Serial_effectivity
  SUBTYPE OF (Effectivity);
  start_id : STRING;
  end_id : OPTIONAL STRING;
END_ENTITY;


start_id: the first valid serial number.

end_id: the last valid serial number. The value of the attribute need not be specified. If the value for this attribute is not specified, the interval of applicability has no upper bound.

Time_interval_effectivity


ENTITY Time_interval_effectivity
  SUBTYPE OF (Effectivity);
  effectivity_period : Time_interval;
END_ENTITY;


effectivity_period: the Time_interval that defines the domain of validity.

From module : effectivity_application - using all


TYPE effectivity_item = EXTENSIBLE SELECT;
END_TYPE;


Effectivity_assignment


ENTITY Effectivity_assignment;
  assigned_effectivity : Effectivity;
  role : STRING;
  items : SET[1:?] OF effectivity_item;
END_ENTITY;


assigned_effectivity: the instance of the Effectivity entity that is assigned.

role:

the text that specifies the purpose of the association of the Effectivity with items.

For an Effectivity that identifies a period of time, if applicable, the following values shall be used:

• 'actual': The assigned_effectivity defines a period of time during which the associated items are or were effective;
• 'planned': The assigned_effectivity defines a period of time during which the associated items are or were expected to be effective;
• 'required': The assigned_effectivity defines a period of time during which the associated items are or were required to be effective.

items: the set of effectivity_item whose effectivity is characterized by this entity.

From module : time_interval - using all

Time_interval


ENTITY Time_interval;
  id : STRING;
  name : STRING;
  description : OPTIONAL STRING;
END_ENTITY;


id: the identifier for the Time_interval.

name: the words by which the Time_interval is known.

description: the text that provides further information about the Time_interval. The value of this attribute need not be specified.

Time_interval_relationship


ENTITY Time_interval_relationship;
  relation_type : STRING;
  description : STRING;
  relating_time_interval : Time_interval;
  related_time_interval : Time_interval;
END_ENTITY;


relation_type: the text that identifies the meaning of the relationship.

description: the text that provides further information about the Time_interval_relationship.

relating_time_interval: the first instance of Time_interval that is part of the relationship.

related_time_interval: the other instance of Time_interval. If one element of the relationship is dependent upon the other, this attribute shall be the dependent one.

Time_interval_with_bounds

If neither secondary_bound nor Duration are specified, the time interval begins at the point in time identified by primary_bound and has no specified end point.


ENTITY Time_interval_with_bounds
  SUBTYPE OF (Time_interval);
  primary_bound : OPTIONAL date_or_event;
  secondary_bound : OPTIONAL date_or_event;
  duration_from_primary_bound : OPTIONAL Duration;
WHERE
  WR1: NOT (EXISTS (secondary_bound) AND EXISTS (duration_from_primary_bound));
  WR2: EXISTS (primary_bound) OR EXISTS (secondary_bound);
END_ENTITY;


primary_bound: the bound of the Time_interval_with_bounds from which the length of the time interval is measured. The value of this attribute need not be specified.

secondary_bound: the other bound of the Time_interval_with_bounds. The value of this attribute need not be specified.

duration_from_primary_bound:

the Duration that specifies the length of the time interval from the primary bound.

If positive, the Time_interval_with_bounds defines a lower bounded time interval, else an upper bounded time interval.

The value of this attribute need not be specified.
