4 Information requirements

This clause specifies the information requirements for the Security classification 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 Security classification schema.

EXPRESS specification:

*)
SCHEMA Security_classification_arm;
(*

4.1 ARM type definition

This subclause specifies the ARM type for this application module. The ARM type and definition is specified below.

4.1.1 security_classification_item   EXPRESS-G

The security_classification_item type is an extensible list of alternate data types. Additional alternate data types are specified in select data types that extend the security_classification_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 security_classification_item = EXTENSIBLE SELECT;
END_TYPE;
(*

4.2 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.

4.2.1 Security_classification   EXPRESS-GMapping table

A Security_classification is a level of confidentiality that can be applied to protect activity or product data against unauthorized usage.

EXPRESS specification:

*)
ENTITY Security_classification;
  classification_level : STRING;
  description : OPTIONAL STRING;
END_ENTITY;
(*

Attribute definitions:

classification_level: the text that specifies the required degree of security.

EXAMPLE    'confidential' is an example of classification_level that may be applied to documents.

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

4.2.2 Security_classification_assignment   EXPRESS-GMapping table

A Security_classification_assignment is an association of a Security_classification with activity or product data.

EXPRESS specification:

*)
ENTITY Security_classification_assignment;
  classification : Security_classification;
  items : SET[1:?] OF security_classification_item;
END_ENTITY;
(*

Attribute definitions:

classification: the Security_classification assigned to activity or product data.

items: the activity or product data to which the Security_classification is assigned.
