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

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.

Annex A
Example of specifications for the design of the software of the
Application Program Interface (API) when it is applied to the SITP and
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.
acquire data list
operation of acquiring the data list from the database, on the specified server
acquire ship information
polling operation from the specified server
Common Object Request Broker Architecture
standard of distributed object model as defined by the Object Management Group
database server

station which became independent of the LITP-installed system and the SITP-installed system, when a

database is arranged on this station
Interface Definition Language
language to define interface in each operation
NOTE CORBA's primary tool to insulate language.
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)
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

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.
naming service interface

program, which executes the API request from the user application, in the series of processes when a naming

service is used
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
Object Request Broker
software which provides the tasks of communication between stub and skeleton
read data

operation of reading one particular datum from the database, on the specified server

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.
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.
write data
operation of writing one particular datum to the dat
