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