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.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

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. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/ patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation on the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following

URL: www .iso .org/ iso/ foreword .html.

This document was prepared by Technical Committee ISO/TC 46, Information and documentation,

Subcommittee SC 4, Technical interoperability.

This third edition of ISO 18626 cancels and replaces the second edition (ISO 18626:2017), of which it

constitutes a revision.
The main changes compared to the previous edition are as follows:

— Several elements have been added to handle identified use cases. As part of this SentVia has been

renamed DeliveryMethod, this element is now used in both the Request and Supplying Agency

messages. This is the only elimination of an element and has been done after consultation with

implementers.
— Annex B has been rewritten to clarify the use of Open Codes.

— Annex D is changed from including several use cases to one sample use case and a link to additional

use cases at the website (ref. Annex A).
— Annex F is added with guidelines about the use of profiles with ISO 18626.
— Annex G is added with guidelines about consortia.

— Annex H is added with guidelines about handling negotiations using “retry” when the supplier

cannot fulfil the first request.

— Added a RetryInfo section to SupplyingAgencyMessage, which should only be used when the Status

is RetryPossible. This section is used in conjunction with the expanded set of ReasonRetry values as

described in Annex H.

— Renamed ServiceInfo/PreferredFormat to ServiceInfo/ItemFormat and renamed DeliveryInfo/

DeliveredFormat to DeliveryInfo/ItemFormat so that we only need one Open Code list for Formats.

— PhysicalAddress/Region has been changed from StandardCodes to free-text field to bring the

PhysicalAddress structure in line with the PhysicalAddress structure used in NCIP (to simplify

implementation).

— For requests the element PreferredEdition has been added. In 18626:2021, the element AnyEdition

will be retained to ensure backward compatibility. In the next version of the standard AnyEdition

will be deprecated in favour of PreferredEdition. It is recommended to upgrade from AnyEdition to

PreferredEdition without unnecessary delay.

Introduction

This document is intended to succeed the old ISO interlibrary lending protocol (consisting of ISO 10160,

ISO 10161-1 and ISO 10161-2). Unlike its predecessor, this document is well suited to the modern,

web-based technological environment which is based on XML and web services. Another important

difference between the two standards is that while ISO 10160 is based on an outdated 1980s model of

ILL transactions, its successor relies on and supports a modern, much simpler ILL procedure.

ISO TC 46/SC 4 made an attempt to revise ILL standards in 2007. The chosen policy — careful revision

of the existing standard — failed, since for some SC 4 P members the revision was too radical, whereas

some other P members indicated that it was not thorough enough. In order to avoid a similar deadlock,

the SC 4 plenary meeting chose a different strategy in 2012. The committee shall keep the old standard

alive as long as necessary by, e.g. making the editorial changes needed. But SC 4 also decided to start

the development of a new, Web-enabled ILL standard.

The new standard specifies three simple messages: a request, a supplying library message and

a requesting library message. The protocol is stateless, which means that there shall be no need to

maintain the interconnected state tables in the client and server applications (and the connections to the

state tables in applications behind them). Implementer experiences gathered from the previous edition

of this ILL protocol indicates that it is easier to implement than ISO 10160 and that the functionality

provided meets the requirements of libraries’ current ILL practices.

This document is the first part of a more general strategic initiative to standardize resource sharing in

ISO/TC46/SC4. As part of this intention, the editors have aligned element names, transport and XML

schema with similar functions in ANSI/NISO Z39.83 NISO Circulation Interchange Protocol.

4 Messages
4.1 General

This document specifies three messages and responses to them for handling interlibrary loan

transactions:
— Request (see Table 1) and Request Confirmation (see Table 2);
2 © ISO 2020 – All rights reserved
---------------------- Page: 10 ----------------------
oSIST ISO/DIS 18626:2021
ISO/DIS 18626:2020(E)

— Supplying Agency Message (see Table 3) and Supplying Agency Message Confirmation (see Table 4);

— Requesting Agency Message (see Table 5) and Requesting Agency Message Confirmation (see

Table 6).

See additional information on guidelines about the use of this document in Annex D. This annex is

illustrative and does not cover all relevant use cases.

For Request, Supplying Agency Message and Requesting Agency Message, a confirmation message

is sent immediately (see 4.3, 4.5 and 4.7). The Request Confirmation message (see Table 2) is not a

positive or negative response to the request; it indicates only that the Request message has been

received. If the Request message contains problems, the Request Confirmation message shall include

Error Data (see 4.10).
Codes used in tables are as follows:
— R Repeatable;
— M Mandatory;
— CT Complex Type;
— OC Open Code List (i.e. Scheme Value Pair);
— CC Closed Code List (i.e. the code list is part of the ILL standard);
— SC Standard Code List.

Open Code Lists are predefined schemes, consisting of an enumerated list of possible values for a given

data element that should be supported by applications conformant with this document. The Open Code

Lists of values are not comprehensive and implementer groups may develop additional schemes for

these enumerated types to cover their implementation requirements. Thus, an application may choose

to support additional schemes for one or more Open Code Lists. Core lists of values to be supported by

all implementations are defined in Annex B.

The lists of values may be derived from standard lists of codes or other registries.

Standard Code Lists are based on code lists published in standards or other normative documents.

New schemes may be added to the Open Code List as described in Annex B.
Complex Types are listed and defined in 4.8.

Closed Code Lists (see 4.9) are a normative part of this document and shall be supported by applications

conformant with this document. They are similar to Open Code Lists, except that Closed Code Lists

of values are expected to be relatively comprehensive and stable. However, new closed code scheme

elements and code values may be added to the future versions of this document.

Date and time shall always be provided in the form YYYY -MM -DDThh: mm: ssZ as specified by

ISO 8601-1. When time is not significant, e.g. when a due date is given, use 23:59:59Z to indicate the

time, for example, 2013-05-15T23:59:59Z.

Use of the identifiers in Table B.1 shall be according to the referred standards: ISIL according to

ISO 15511, ISBN according to ISO 2108, ISSN according to ISO 3297, ISMN according to ISO 10957 and

DOI according to ISO 26324.

Use of the currency symbols referenced in Table 7 shall be as specified in ISO 4217.

4.2 Request
The Request contains information about the item and service requested.
