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 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.
ISO 28560-3 was prepared by Technical Committee ISO/TC 46, Information and documentation,
Subcommittee SC 4, Technical interoperability.
ISO 28560 consists of the following parts, under the general title Information and documentation — RFID in
libraries:
⎯ Part 1: Data elements and general guidelines for implementation
⎯ Part 2: Encoding of RFID data elements based on rules from ISO/IEC 15962
⎯ Part 3: Fixed length encoding

Introduction
Libraries are implementing RFID (radio frequency identification) 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 (DS/INF 163-1).
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 a basic set of data elements in a fixed length format and the
rest of the data elements in optional extension blocks. ISO 28560-1 defines the set of mandatory and optional
data elements.
ISO 28560-2 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 28560-2, or to some proprietary rules. Depending on the technologies being used, and other
features of tags that are claiming compliance with ISO 28560-2, the reading system might achieve a degree of
interoperability.
ISO 28560 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 ISO 28560.

INTERNATIONAL STANDARD ISO 28560-3:2011(E)

Information and documentation — RFID in libraries —
Part 3:
Fixed length encoding
1 Scope
This part of ISO 28560 provides 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 academic, public, corporate,
special and school libraries).
This part of ISO 28560 specifies the rules for encoding
⎯ a subset of data elements taken from the total set of data elements listed in ISO 28560-1 into a basic
block, and
⎯ other data elements into extension blocks
onto the RFID tag.
A source of additional information about implementation issues is provided in Annex A.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 28560-1 and the following apply.
3.1
basic block
data block occupying the first 272 bits of the RFID tag
NOTE If the RFID tag is limited to 256 bits (i.e. 32 bytes), the basic block is truncated.
3.2
byte
8-bit byte
group of eight consecutive bits
NOTE A byte can represent one character (3.3) or be part of a representation of a character.
3.3
character
one or more bytes (3.2)
3.4
CRC
cyclic redundancy check
value calculated from the data on the tag
3.5
data block
container for encoding data elements, CRC (3.4), filler and end mark
3.6
end block
data block (3.5) containing the end mark terminating the information on the RFID tag
3.7
extension block
optional data block (3.5) following the basic block (3.1)
3.8
field
entry in a data block (3.5)
3.9
filler data block
optional data block (3.5) that may be inserted to align other data blocks on page (3.11) boundaries
3.10
fixed length field
field (3.8) of prescribed siz
