this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

INTRODUCTION
This technical report describes the methodology for integrated use of heterogeneous libraries
of electric and electronic product parts to provide integrated services utilizing existing
heterogeneous libraries. Integrated search of electronic parts information, for example,
requires to integrate the electronic parts classification systems and the property classification
systems that are possibly maintained by different nations in incompatible ways, in that not all
the electronic parts information has one-to-one correspondence between parts libraries.
Recently, Korea, China, and Japan jointly built an integrated search system to enable search
of parts information across parts libraries that are independently operated by each country.
The biggest challenge in this project was bridging the gap between these heterogeneous
parts libraries by providing rules to integrate related parts information. The integration of
information that has one-to-one (1:1) relation between different parts libraries is
straightforward. However, integration of information that has one-to-many (1:N), or many-to-
one (N:1) relation demands a standard rule of integration to provide a determinant search
result, or service in general.
The integration rules specified in this technical report provide a foundation for utilization of the
electronic parts libraries, possibly heterogeneously constructed by different organizations.
The information systems constructed by the application of these integration rules can be the
basis for constructing an integrated electronic parts e-sourcing system enabling real-time
search of multinational electronic part databases with minimized loss of information.

MAPPING RULES AND EXCHANGE METHODS FOR
HETEROGENEOUS ELECTRONIC PARTS LIBRARIES –

Part 1: Building an integrated search system

1 Scope
This part of IEC 62699 describes mapping rules and exchange methods for the development
of general and extendable integrated services utilizing heterogeneous multi-national or multi-
enterprise electronic parts library data. The scope of this technical report is as follows:
a) identification and classification of mapping types for mapping heterogeneous electronic
parts libraries;
b) definition of general mapping rules and specific mapping rules commonly applying to
various mapping types.
The following aspects are out of the scope of this technical report:
• schematic definition and management of the electronic parts libraries to be mapped;
• maintenance process for the parts libraries during changes.
2 Application architecture
2.1 General
This clause illustrates the application architecture on which the mapping rules and methods
are based. The information exchange methodology and interoperability are required for
performing an integrated search by linkage of heterogeneous electronic parts libraries on the
basis of the mapping dictionary.
2.2 Interoperability system
Figure 1 shows an interoperability system (IOS). It is constructed with common exchange
rules and a mapping dictionary that apply between parties A, B and C. Each system,
connected with the Internet, provides the communications environment that enables data
exchange.
– 8 – IEC TR 62699-1 © IEC 2014

IEC
Figure 1 – Interoperability system status
The following items are involved in the construction of an application architecture.
• Interoperability system (IOS)
It consists of the mapping dictionary, suppliers' list and the parts data base (DB) intended
to design communications protocols and message exchange rules enabling interoperation,
and to provide and exchange developed data communications programs and data.
• Mapping dictionary
It constructs electronic parts libraries into the mapping dictionary for information exchange
between sites.
• Part DB
As detailed information of the parts listed in the mapping dictionary. It can be either
operated on the same server as the interoperability system or constructed into a separate
system depending on the information system environments of the concerned site.

IEC TR 62699-1 © IEC 2014 – 9 –

2.3 Architecture
IEC
Figure 2 – Application architecture
Figure 2 shows the organization of the application architecture in which each component
provides the functions as described below.
• Presentation layer (User Interface)
It inputs search conditions for search of parts information and provides the user screen on
which search results are displayed.
• Interface layer (request & response adapter)
It consists of the request demanding the interoperability system to search the parts
information according to search conditions (class, suppliers' list, property, etc.) and the
response transporting the parts information search results corresponding to the requested
search conditions in response to the request.
• Conversion layer (transportation, mapping)
It executes data conversion and mapping in accordance with the requested search
conditions and the IOS through the mapping dictionary and suppliers' list.
• Suppliers' list
It is the supplier information corresponding to a parts class and includes information such
as URL, address, etc.
• Mapping dictionary
It is the repository in which parts classes of each interoperability system site to be
exchanged are mapped. All the sites whose information will be exchanged should always
be synchronized to ensure accurate information exchange.

– 10 – IEC TR 62699-1 © IEC 2014

• Part DB
As the repository of detailed information of supplier’s parts, it is the supplier system which
is constructed outside the interoperability system and configured to be linked to the
interoperability system.
• Logger
It monitors the transaction processing of the interoperability system such as request,
response, etc., and the system management. It contains the standard message protocol,
standard mapping dictionary and parts information for exchange of parts information. The
standard message protocol defines the method of communications used for data transport
and the method of packaging data in the message.
2.4 Data flow diagram
Figure 3 depicts the data flow in the application architecture.
