Project: Location Independent Information Object Security
(IOS)

Bolt Beranek and Newman, Inc. (BBN), under contract to the
Advanced Research Projects Agency (ARPA), has developed the
Information Object Security (IOS) Tools.  These tools use
object identifiers which are registered as Computer Security
Objects.  ARPA has unlimited rights in the software
containing the objects.  BBN specified, created, and named
the objects under contract to ARPA, and remains the primary
point of contact on all questions regarding naming
conflicts.  The NIST Computer Security Objects Register
(CSOR) assumes no responsibility pertaining to any inquiry
regarding ownership or naming conflicts. 

The IOS software is publicly available and can be obtained
on the Internet for anonymous ftp at ests.bbn.com.

Object definition and description
---------------------------------

The linear annotation component is one of several components
defined by the Location Independent Information Object
Security (IOS) project.  The IOS components are used singly
or in combination with others to achieve a variety of
security services.

This is a syntax that denotes an IOS linear annotation
component.  The linear annotation component is used to carry
annotations to a user document.  See the
id-ios-annotationComponent documentation for definitions of
an AnnotationComponent.

    LinearNotation ::= SEQUENCE {
     start               INTEGER,
     stop                INTEGER,
     comment             T61String }


Object usage and rules
-----------------------

The annotation component allows commentary on one or more
referenced components.  Commentary can be applied to all
and/or portions of each referenced component.  For the
LinearNotation, the "start" and "stop" define the range of
the annotation, where 'start' specifies the offset of the
first octet being annotated, and 'stop'  specifies the
offset of the octet after the last octet being annotated. 
This notation is intended for linear objects, such as text
files.
