This clause specifies the information requirements for the
Time interval 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.
The following EXPRESS specification begins the
Time_interval_assignment_arm
schema and identifies the necessary external references.
EXPRESS specification:
*)
SCHEMA Time_interval_assignment_arm;

The following EXPRESS interface statement specifies the elements
imported from the ARM of another application module.

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

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 time_interval_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 time_interval_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
time_interval_item =
EXTENSIBLE
SELECT;
END_TYPE;
(*
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.
A Time_interval_assignment is an association of a Time_interval
with product data.
EXPRESS specification:
*)
ENTITY Time_interval_assignment;
assigned_time_interval : Time_interval;
role : Time_interval_role;
items : SET[1:?] OF time_interval_item;
END_ENTITY;
(*
Attribute definitions:
assigned_time_interval:
the instance of the Time_interval entity data type that is associated with product data.
role:
the Time_interval_role that specifies the meaning of the Time_interval with respect to the product data.
items:
the product data to which the Time_interval is assigned.
A Time_interval_role is a role for an
Time_interval_assignment and a description of that role.
NOTE
This entity data type is intended to be used with instances of Time_interval_assignment.
EXPRESS specification:
*)
ENTITY Time_interval_role;
name : STRING;
description : STRING;
END_ENTITY;
(*
Attribute definitions:
name:
the words by which the Time_interval_role is known.
description:
the
text that provides further information about the Time_interval_role.
