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 3.
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 part of ISO 9735 may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 9735-3 was prepared by Technical Committee ISO/TC 154, Processes, data elements and documents in
commerce, industry and administration in collaboration with UN/CEFACT through the Joint Syntax Working Group
(JSWG).
This second edition cancels and replaces the first edition (ISO 9735-3:1998). However ISO 9735:1988 and its
Amendment 1:1992 are provisionally retained for the reasons given in clause 2.
Furthermore, for maintenance reasons the Syntax service directories have been removed from all parts of the
ISO 9735 series. They are now consolidated in a new part, ISO 9735-10.
At the time of publication of ISO 9735-1:1998, ISO 9735-10 had been allocated as a part for “Security rules for
interactive EDI”. This was subsequently withdrawn because of lack of user support, and as a result, all relevant
references to the title “Security rules for interactive EDI” were removed in this second edition of ISO 9735-3.
Definitions from all parts of the ISO 9735 series have been consolidated and included in ISO 9735-1.
ISO 9735 consists of the following parts, under the general title Electronic data interchange for administration,
commerce and transport (EDIFACT) — Application level syntax rules (Syntax version number: 4, Syntax release
number: 1):
— Part 1: Syntax rules common to all parts
— Part 2: Syntax rules specific to batch EDI
— Part 3: Syntax rules specific to interactive EDI
— Part 4: Syntax and service report message for batch EDI (message type — CONTRL)
— Part 5: Security rules for batch EDI (authenticity, integrity and non-repudiation of origin)
— Part 6: Secure authentication and acknowledgement message (message type — AUTACK)
— Part 7: Security rules for batch EDI (confidentiality)
— Part 8: Associated data in EDI
iv © ISO 2002 – All rights reserved
— Part 9: Security key and certificate management message (message type — KEYMAN)
— Part 10: Syntax service directories
Further parts may be added in the future.
Annexes A, B and C of this part of ISO 9735 are for information only.
Introduction
This part of ISO 9735 includes the rules at the application level for the structuring of data in the interchange of
electronic messages in an open environment, based on the requirements of either batch or interactive processing.
These rules have been agreed by the United Nations Economic Commission for Europe (UN/ECE) as syntax rules
for Electronic Data Interchange for Administration, Commerce and Transport (EDIFACT) and are part of the United
Nations Trade Data Interchange Directory (UNTDID) which also includes both batch and interactive Message
Design Guidelines.
This part of ISO 9735 may be used in any application, but messages using these rules may only be referred to as
EDIFACT messages if they comply with other guidelines, rules and directories in the UNTDID. For UN/EDIFACT
interactive messages, the message design rules for interactive usage apply. These rules are maintained in the
UNTDID.
Communications specifications and protocols are outside the scope of this part of ISO 9735.
This is a new part, which has been added to ISO 9735. It provides for the exchange of EDIFACT messages in an
interactive (conversational) EDI environment.
Interactive EDI (I-EDI) is characterized by the following:
a formalized association between the two parties using a dialogue;
the ability, dynamically, to direct the course of the I-EDI transaction, depending upon the result of earlier
exchanges within the dialogue;
short response times;
all the messages exchanged within one dialogue relate to the same business transaction;
a transaction is a controlled set of dialogues which can take place between two or more parties.
These characteristics differentiate I-EDI from batch EDI which is specified in ISO 9735-2 (syntax rules specific to
batch EDI).
For consistency and in order to simplify the implementation of the standard for those users who wish to utilize both
batch and interactive processing, this part of ISO 9735 has been aligned as far as possible with ISO 9735-2.

Part 3:
Syntax rules specific to interactive EDI
1 Scope
This part of ISO 9735 specifies syntax rules specifically for the transfer of interactive messages to be interchanged
between computer application systems. For the transfer of packages in an interactive environment, see
ISO 9735-8.
2 Conformance
Whereas this part shall use a version number of “4” in the mandatory data element 0002 (Syntax version number),
and shall use a release number of “01” in the conditional data element 0076 (Syntax release number), each of
which appear in the segment UNB (Interchange header), interchanges continuing to use the syntax defined in the
earlier published versions shall use the following Syntax version numbers, in order to differentiate them from each
other and from this part:
ISO 9735:1988: Syntax version number: 1
ISO 9735:1988 (amended and reprinted in 1990): Syntax version number: 2
ISO 9735:1988 and its Amendment 1:1992: Syntax version number: 3
ISO 9735:1998: Syntax version number: 4
Conformance to a standard means that all of its requirements, including all options, are supported. If all options are
not supported, any claim of conformance shall include a statement which identifies those options to which
conformance is claimed.
Data that is interchanged is in conformance if the structure and representation of the data conforms to the syntax
rules specified in this part of ISO 9735.
Devices supporting this part of ISO 9735 are in conformance when they are capable of creating and/or interpreting
the data structured and represented in conformance with the standard.
Conformance to this part of ISO 9735 shall include conformance to ISO 9735-1 and ISO 9735-10.
When identified in this part of ISO 9735, provisions defined in related standards shall form part of the conformance
criteria.
3 Normative references
The following normative documents contain provisions which, through reference in this text, constitute provisions of
this part of ISO 9735. For dated references, subsequent amendments to, or revisions of, any of these publications
do not apply. However, parties to agreements based on this part of ISO 9735 are encouraged to investigate the
possibility of applying the most recent editions of the normative documents indicated below. For undated
references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain
registers of currently valid International Standards.

These rules have been agreed by the United Nations Economic Commission for Europe (UN/ECE) as syntax rules for Electronic Data Interchange for Administration, Commerce and Transport (EDIFACT) and are part of the United Nations Trade Data Interchange Directory (UNTDID) which also includes both batch and interactive Message Design Guidelines. This part of ISO 9735 may be used in any application, but messages using these rules may only be referred to as EDIFACT messages if they comply with other guidelines, rules and directories in the UNTDID. For UN/EDIFACT interactive messages, the message design rules for interactive usage apply. These rules are maintained in the UNTDID. Communications specifications and protocols are outside the scope of this part of ISO 9735. This is a new part, which has been added to ISO 9735. It provides for the exchange of EDIFACT messages in an interactive (conversational) EDI environment. Interactive EDI (I-EDI) is characterized by the following: a formalized association between the two parties using a dialogue; the ability, dynamically, to direct the course of the I-EDI transaction, depending upon the result of earlier exchanges within the dialogue; short response times; all the messages exchanged within one dialogue relate to the same business transaction; a transaction is a controlled set of dialogues which can take place between two or more parties. These characteristics differentiate I-EDI from batch EDI which is specified in ISO 9735-2 (syntax rules specific to batch EDI). For consistency and in order to simplify the implementation of the standard for those users who wish to utilize both batch and interactive processing, this part of ISO 9735 has been aligned as far as possible with ISO 9735-2.
INTERNATIONAL STANDARD ISO 9735-3:2002(E) © ISO 2002 – All rights reserved 1 Electronic data interchange for administration, commerce and transport (EDIFACT) — Application level syntax rules (Syntax version number: 4, Syntax release number: 1) — Part 3: Syntax rules specific to interactive EDI 1 Scope This part of ISO 9735 specifies syntax rules specifically for the transfer of interactive messages to be interchanged between computer application systems. For the transfer of packages in an interactive environment, see ISO 9735-8. 2 Conformance Whereas this part shall use a version number of “4” in the mandatory data element 0002 (Syntax version number), and shall use a release number of “01” in the conditional data element 0076 (Syntax release number), each of which appear in the segment UNB (Interchange header), interchanges continuing to use the syntax defined in the earlier published versions shall use the following Syntax version numbers, in order to differentiate them from each other and from this part: ISO 9735:1988: Syntax version number: 1 ISO 9735:1988 (amended and reprinted in 1990): Syntax version number: 2 ISO 9735:1988 and its Amendment 1:1992: Syntax version number: 3 ISO 9735:1998: Syntax version number: 4 Conformance to a standard means that all of its requirements, including all options, are supported. If all options are not supported, any claim of conformance shall include a statement which identifies those options to which conformance is claimed. Data that is interchanged is in conformance if the structure and representation of the data conforms to the syntax rules specified in this part of ISO 9735. Devices supporting this part of ISO 9735 are in conformance when they are capable of creating and/or interpreting the data structured and represented in conformance with the standard. Conformance to this part of ISO 9735 shall include conformance to ISO 9735-1 and ISO 9735-10. When identified in this part of ISO 9735, provisions defined in related standards shall form part of the conformance criteria.
3 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of ISO 9735. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part of ISO 9735 are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards. ISO 9735-1:2002, Electronic data interchange for administration, commerce and transport (EDIFACT) — Application level syntax rules (Syntax version number: 4, Syntax release number: 1) — Part 1: Syntax rules common to all parts ISO 9735-10:2002, Electronic data interchange for administration, commerce and transport (EDIFACT) — Application level syntax rules (Syntax version number: 4, Syntax release number: 1) — Part 10: Syntax service directories 4 Terms and definitions For the purposes of this part of ISO 9735, the terms and definitions given in ISO 9735-1 apply. 5 I-EDI interchange structure The service string advice (if used) and the header and trailer service segments shall appear in an I-EDI interchange in the order shown in Figure 1.
Figure 1 — I-EDI interchange structure In Figure 1, the lines to the left show the pairing of header and trailer segments. For simplicity, an interchange containing only one message is shown. For the specification of the service string advice, see ISO 9735-1:2002, annex A. For the specification of the interactive header and trailer segments, see ISO 9735-10. NOTE Segments for use in UN/EDIFACT messages are defined in the United Nations Trade Data Interchange Directory (UNTDID).
NOTE The default service characters are used for illustrative purposes. Figure 2 — I-EDI message within a transaction
