Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
Amendment 1 to ISO 15849:2001 was prepared by Technical Committee ISO/TC 8, Ships and marine
technology, Subcommittee SC 10, Computer applications.

Introduction
Annex A indicates an example of the specifications for the design of the software of the Application Program
Interface (API) when it is applied to the SITP and the LITP, as required by the main text of ISO 15849
(Guidelines for the Fleet Management System Network, FMSN) to secure the effective execution of the mutual
connectivity with transparency.

Ships and marine technology — Guidelines for implementation
of a fleet management system network
AMENDMENT 1: Annex A
ISO 15849:2001/Amd.1:2003(E)
Annex A
(informative)
Example of specifications for the design of the software of the
Application Program Interface (API) when it is applied to the SITP and
LITP
A.1 Scope
The scope of this Annex is the software design guide for the purpose of applying the API for the functions of
the SITP and the LITP that are specified in the main text of ISO 15849.
In this Annex, the concept is based on the use of CORBA (A.2.3) as the specification of a distributed object for
a model.
A.2 Terms and definitions
For the purposes of this Annex, the following terms and definitions apply.
A.2.1
acquire data list
operation of acquiring the data list from the database, on the specified server
A.2.2
acquire ship information
polling operation from the specified server
A.2.3
CORBA
Common Object Request Broker Architecture
standard of distributed object model as defined by the Object Management Group
A.2.4
database server
station which became independent of the LITP-installed system and the SITP-installed system, when a
database is arranged on this station
A.2.5
IDL
Interface Definition Language
language to define interface in each operation
NOTE CORBA's primary tool to insulate language.
A.2.6
IDL skeleton
when CORBA is used and the client and server communicate, a program (as a part of API) on the server side
to provide an application program to start the operation directly

ISO 15849:2001/Amd.1:2003(E)
A.2.7
IDL stub
when CORBA is used and the client and server communicate, the client program that accesses the operation
on the server side provided with the corresponding pseudo-object (as a part of API) on the client side
A.2.8
naming service
common reference service provided by CORBA
NOTE The naming service responds to the inquiry from the object, relating the name of the object to its location in
the network.
A.2.9
naming service interface
program, which executes the API request from the user application, in the series of processes when a naming
service is used
A.2.10
OMG
Object Management Group
international standardization group which prescribes technology for the infrastructure which is necessary for
the development of the application in the environment of the dispersion of object oriented architecture and
independent of the hardware
A.2.11
ORB
Object Request Broker
software which provides the tasks of communication between stub and skeleton
A.2.12
read data
operation of reading one particular datum from the database, on the specified server
A.2.13
user application
program, which is established by the user of the FMSN in accordance with the requirement by the
LITP-installed system to realize the functionality on the FMSN
NOTE The functionality on the FMSN serves to acquire the operational management information and/or the ship
management information.
A.2.14
user-application interface
interface in the API opened between the API and user application
NOTE This also defines four kinds of operation (Read data, Write data, Acquire data list and Acquire ship
information) as described in the A.4.1.2 to A.4.3.2.
A.2.15
write data
operation of writing one particular datum to the dat
