ISO 28560-2:2014(E)

Introduction
Libraries are implementing radio frequency identification (RFID) as item identification to replace bar
codes. RFID streamlines applications like user self-service, security, and materials handling. A standard
data model for encoding information on RFID tags could increase the cost-effectiveness of the technology
within libraries, particularly through greater interoperability of RFID tags and equipment, and enhance
support for resource sharing between libraries.
Several countries have undertaken preliminary work on standardization. The Netherlands developed
a data model for public libraries and in Denmark “RFID Data Model for Libraries” has been published.
Finland has adopted the Danish model, but with a few changes. There is a French data model that differs
from the Danish and Dutch models. Other libraries in different parts of the world have installations
based on various proprietary systems offered by technology and library system suppliers. All of these
constitute the installed base of RFID systems, but only account for a small minority of the total of
libraries globally.
There is an opportunity to develop a standard data model, taking into account the lessons learned from
the national schemes and vendor solutions, and provide migration options for those libraries that have
already invested in the technology. Because new items are continually being purchased, a number of
migration options can be adopted based on factors relevant to each library.
This part of ISO 28560 deals with the encoding of data elements in a flexible manner using encoding
rules that are specified in ISO/IEC 15962. ISO 28560-1 defines the set of mandatory and optional data
elements.
ISO 28560-3 and this part of ISO 28560 are mutually exclusive with respect to an RFID tag being applied
to a loan item. In other words, the RFID tag is encoded according to the rules of this part of ISO 28560,
or to the rules of ISO 28560-3, or to some proprietary rules. Depending on the technologies being used,
and other features of tags that are claiming compliance with this part of ISO 28560, the reading system
might achieve a degree of interoperability.
This International Standard provides essential standards-based information about RFID in libraries.
Ongoing advice needs to be provided because of the evolving nature of RFID technology, and the
opportunities to migrate between different types of legacy system and encoding rules of this
International Standard.

INTERNATIONAL STANDARD ISO 28560-2:2014(E)
Information and documentation — RFID in libraries —
Part 2:
Encoding of RFID data elements based on rules from ISO/
IEC 15962
1 Scope
This part of ISO 28560 specifies a data model and encoding rules for the use of radio frequency
identification (RFID) tags for items appropriate for the needs of all types of libraries (including national,
academic, public, corporate, special, and school libraries). The rules for encoding a subset of data
elements taken from the total set of data elements defined in ISO 28560-1 are based on ISO/IEC 15962,
which uses an object identifier structure to identify data elements.
This part of ISO 28560 defines the technical characteristics required to encode the data elements defined
in ISO 28560-1 in accordance with ISO/IEC 15962. These subsets of data elements can be different on
different items in the same library. The encoding rules also enable the optional data to be organized on
the RFID tag in any sequence. In addition, the encoding rules provide for flexible encoding of variable
length and variable format data.
This part of ISO 28560 provides essential standards-based information about RFID in libraries. A source
of additional information about implementation issues is provided in Annex A.

4 Applicability and relationship with other systems
4.1 Figure 1 gives an overview of the relationship of this part of ISO 28560 with other systems. This
part of ISO 28560 defines a set of technical features while addressing a number of operational issues. This
part of ISO 28560 interfaces with four other activities, but with a clearly defined overlap. These other
activities are
— the circulation of library materials,
— the data requirements of publishers, printers, and other suppliers,
— the interlibrary loan processes, and
— the details of borrowers, including membership cards.
4.2 Figure 1 also shows that there is a direct relationship with supply chain activities, and internally
within the library with RFID circulation devices and the library management system including interfaces
such as SIP2 and NCIP.
As the use of RFID in libraries moves towards a more standardized approach as defined in this part of
ISO 28560, the characteristics and architecture systems change compared to those already established.
To achieve interoperability with equipment and software, the required features include
— the air interface protocol, which defines the way readers and tags communicate with one another,
— the data protocol, which defines the encoding rules that convert application-based data to the
encoded bytes on the RFID tag; the data protocol also defines metadata features in the RFID tag to
protect the integrity of RFID for library systems in relation to other RFID applications,
— the set of data elements that form the dictionary from which individual libraries can choose those
that are most appropriate for their operation.
4.3 By adopting this part of ISO 28560, libraries will have increased flexibility with a number of features
as follows.
— Beyond the minimum of mandatory data elements defined in this part of ISO 28560, libraries is able
to choose from the optional data elements those that are more appropriate to its application, even
varying these for different types of item.
— Libraries should be able to rank the optional data elements into an appropriate order for encoding
on the RFID tag to support fast transactions across the air interface.

ISO 28560-2:2014(E)

— Libraries have a greater choice of interoperable RFID equipment, and should be able to select RFID
tags with an appropriate size of memory.
— Some degree of choice in the types of security system becomes a library responsibility.
— Libraries with an installed base of RFID data capture is offered options on how to migrate to the
more open standard solution.
— The library community, as a whole and through developments of this part of ISO 28560, is provided
with future options to cope with changes within the RFID equipment as the technology develops.
This includes ensuring that new open systems applications do not corrupt the established base of
RFID systems in libraries.

5 Requirements
5.1 Data elements
The data elements shall be compliant with ISO 28560-1.
NOTE There is a degree of flexibility in using locally defined codes that enable enhancements and variations
to be implemented while still complying with the basic set of data elements.
5.2 RFID air interface
5.2.1 General
The air interface for compliant tags is specified in ISO/IEC 18000-3, specifically the specification for
Mode 1.
For migration purposes, additional non-compliant air interfaces used in legacy systems can be supported
during a transition period, which is permitted to remain in place for years as necessary.
5.2.2 Air interface conformance
The air interface conformance shall be tested in accordance with the procedures of ISO/IEC TR 18047-3.
5.2.3 Tag performance
Where there are requirements for testing tag performance, these shall be done in accordance with
ISO/IEC 18046-3.
5.3 Data protocol
ISO/IEC 15961-1 specifies the application commands that are used to define the communication
requirements between the application and the RFID tag. The relevant commands are described in
Annex B.
The process rules of ISO/IEC 15962 shall be used to encode and decode data from the RFID tag. In
particular, the following constraints shall apply.
— The only encoding rules shall be based on the No-directory access method. No alternative access
method shall be supported until this part of ISO 28560 is revised.
— Both the hard-coded and software-encoded DSFID shall be supported, depending on the capabilities
of the RFID tag.
5.4 RFID readers
In order to achieve interoperability, RFID readers shall be based on open architecture RFID standards
defined by ISO/IEC Joint Technical Committee JTC 1/SC 31. Particular standards are specified in this
part of ISO 28560. This means that any one manufacturer’s reading/writing equipment shall be able to
read or write to any other manufacturer’s RFID tags, and that any manufacturer’s RFID tags shall be
able to be read and/or programmed by any other manufacturer’s reader/writer.
6 Data elements
6.1 General
The set of data elements that comprises the data dictionary for this part of ISO 28560 is fully described
in ISO 28560-1 and repeated in outline in Table 1. Only one data element is mandatory, the primary item

identifier. All others are optional, but can be selected to meet the requirements of individual libraries,
and/or for particular items.
Table 1 shows the Relative-OID value, the format for input data, and advice about locking the data
element as an encoded data set on the RFID tag. A maximum length of 255 characters should apply to all
data elements that have a variable length display format.
