4 Information requirements

This clause specifies the information requirements for the Product environment observed 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 Product_environment_observed_arm schema and identifies the necessary external references.

4.1 Required AM ARMs

The following EXPRESS interface statements specify the elements imported from the ARMs of other application modules.

4.2 ARM type definitions

This subclause specifies the ARM types for this application module. The ARM types and definitions are specified below.

4.2.1 env_obs_classification_item   

The env_obs_classification_item type is an extension of the classification_item type. It adds the data types Observed_environment, Observed_environment_assignment, Observed_environment_version and Observed_environment_view_definition_relationship to the list of alternate data types.

NOTE  The list of entity data types may be extended in application modules that use the constructs of this module.

EXPRESS specification:

*)
TYPE env_obs_classification_item = EXTENSIBLE GENERIC_ENTITY SELECT BASED_ON classification_item WITH
   (Observed_environment,
    Observed_environment_assignment,
    Observed_environment_version,
    Observed_environment_view_definition_relationship);
END_TYPE;
(*

4.2.2 env_obs_identification_assignment   

The env_obs_identification_assignment type is an extension of the identification_item type. It adds the data types Observed_environment, Observed_environment_assignment, Observed_environment_version and Observed_environment_view_definition_relationship to the list of alternate data types.

NOTE  The list of entity data types may be extended in application modules that use the constructs of this module.

EXPRESS specification:

*)
TYPE env_obs_identification_assignment = EXTENSIBLE GENERIC_ENTITY SELECT BASED_ON identification_item WITH
   (Observed_environment,
    Observed_environment_assignment,
    Observed_environment_version,
    Observed_environment_view_definition_relationship);
END_TYPE;
(*

4.2.3 observed_environment_item   

The observed_environment_item type is an extensible list of alternate data types. Additional alternate data types are specified in select data types that extend the observed_environment_item type.

NOTE   This empty extensible select requires extension in a further module to ensure that entities that refer to it have at least one valid instantiation.

EXPRESS specification:

*)
TYPE observed_environment_item = EXTENSIBLE GENERIC_ENTITY SELECT;
END_TYPE;
(*

4.3 ARM entity definitions
