This clause specifies the information requirements for the
Date time assignment
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
Date_time_assignment_arm
schema and identifies the necessary external references.
EXPRESS specification:
*)
SCHEMA Date_time_assignment_arm;
(*
The following EXPRESS interface statement specifies the elements
imported from the ARM of another application module.
EXPRESS specification:

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

ISO/TS 10303-1776 |
NOTE 2
See Annex C,
Figures
C.1and C.2
for a graphical representation of this schema.
This subclause specifies the ARM type
for this application module. The ARM type and
definition is specified below.
A date_or_date_time_item type is an extensible list of alternate entity data types.
It provides a mechanism to refer to instances of the data types included in the types
that extend the date_or_date_time_item type.
NOTE
This empty extensible select type requires extension in a further module,
to ensure that any entity data type that refers to it can have a valid instantiation.
EXPRESS specification:
*)
TYPE
date_or_date_time_item =
EXTENSIBLE
SELECT;
END_TYPE;
(*
This subclause specifies the ARM entity for this
module. The ARM entity is an atomic element that
embodies a unique application concept and contains attributes
specifying the data elements of the entity. The ARM
entity and definition is specified below.
A Date_or_date_time_assignment is an association of a Calendar_date
or a Date_time
with activity or product data.
EXPRESS specification:
*)
ENTITY Date_or_date_time_assignment;
assigned_date : date_or_date_time_select;
role : STRING;
items : SET[1:?] OF date_or_date_time_item;
END_ENTITY;
(*
Attribute definitions:
assigned_date:
the Calendar_date
or the Date_time
that is
assigned to activity or product data.
role:
the text that specifies the purpose of the association between the Calendar_date
or
the Date_time
with activity or product data.
items:
the activity or product data to which the Calendar_date
or
Date_time
is assigned.
