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 rowcol 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 rowcol annotation
component.  The rowcol annotation component is used to carry
annotations to a user document. See the
id-ios-annotationComponent documentation for definitions of
an annotationComponent.


    RowColNotation ::= SEQUENCE {
     start               RowCol,
     stop                RowCol,
     comment             T61String }

    RowCol ::= SEQUENCE {
     row                 INTEGER,
     col                 INTEGER }

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.  The rowcol
notation might be an alternative to the linear notation
since many editors have a concept of line number and column
within the line.  It can also be used with spreadsheets.
