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. This
standard data model for encoding information on RFID tags increases 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.
This document deals with data elements and provides general guidelines for implementation. Other
parts of the ISO 28560 series describe encodings and choice of frequency.
Communication between the RFID reader and the library system (or other applications) is handled by,
[12] [13]
for example, SIP-2 and NCIP .
This document 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 document.

INTERNATIONAL STANDARD ISO 28560-1:2023(E)
Information and documentation — RFID in libraries —
Part 1:
Data elements and general guidelines for implementation
1 Scope
This document specifies a model 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.
It provides the framework to ensure interoperability between libraries that exchange library items with
RFID tags, the freedom of the library to acquire or renew equipment or library items from different
vendors, and interoperability of a single RFID application from the vendor's perspective.
This document specifies a set of data elements and general guidelines for implementation, to meet the
needs for:
— circulation of library items;
— acquisition of library items;
— interlibrary loan processes;
— data requirements of publishers, printers, and other suppliers of library items;
— inventory and stock checking of items.
This document gives guidelines for item security, profiles, privacy, implementation, migration, label
design, and location of the RFID label. It specifies the data model, system data elements, and user
data elements to be used in conjunction with ISO 28560-2, ISO 28560-3, and any future parts of the
ISO 28560 series.
A source of additional information about implementation issues is provided in Annex A.

4 User data elements
4.1 Overview of user data elements
Libraries can choose which data elements they want to store on the tag. It is unlikely that a library
places all the listed data elements on the tag. A number of data elements are reserved for local use. They
should be ignored where the processing institution is not the owner of the item (as in ILL).

4.2 Use of user data elements
4.2.1 Primary item identifier
The library's unique identification of an item shall be used as the primary item identifier. This data
element is required for circulation. It can be absent in the acquisition process.
The primary item identifier can be, but need not be, equivalent to the (former) bar code. It can be
decided at a local or national level if the identifier should be unique outside the library and how this is
to be achieved.
Annex B illustrates how the primary item identifier can be combined with other data to achieve
increasing levels of uniqueness, ultimately global uniqueness.
4.2.2 Content parameter
The content parameter data element specifies the structure of the tag data. The parameter can
have different forms for the various possible encoding methodologies specified in other parts of the
ISO 28560 series.
4.2.3 Owner institution (ISIL)
The owner institution (ISIL) data element is used for the ISIL code for the institution that owns the item.
The ISIL code shall be as defined in ISO 15511.
The list of ISIL agencies that are responsible for the issuing process of ISIL codes can be found at http://
biblstandard .dk/ isil/ .
In exceptional cases, the ISIL code, or parts of the ISIL code, can be stored in data element 23 (alternative
owner institution).
4.2.4 Set information
4.2.4.1 General
If the set information data element is encoded, it shall consist of two components, which are
a) the “number of parts in item”, followed by
b) the “ordinal part number”,
as specified in 4.2.4.2 and 4.2.4.3. These two component parameters are used to identify various
permutations relating to sets.
A single part item is the default case. A system reading a tag that does not contain the set information
data element can assume that the item has only a single part.
4.2.4.2 Numbers of parts in item
For sets with only a single part, the “numbers of parts in item” component shall take the value “1”.
For sets with more than a single part, the “numbers of parts in item” component shall take a value in the
range 0 to 255, where a positive number indicates the total number of parts in the set, and 0 that the
total number is not known.
4.2.4.3 Ordinal part number
For sets with only a single part, the “ordinal part number” component shall take the value “1”.
For sets with more than a single part, the “ordinal part number” component shall take a value in the
range 0 to 255, under one of the following two conditions.
— If all parts in the set carry an RFID tag, a positive ordinal part number corresponding to the
placement of the part in the set shall be assigned to each part.
— If only some of the parts in the set carry an RFID tag, the first part shall be assigned the ordinal part
number 0, and the following parts an ordinal part number corresponding to the placement of the
part in the set. As a consequence, no part shall be assigned the ordinal part number 1.
4.2.4.4 Examples
EXAMPLE 1 A set with three parts, all with their own RFID tags:
— Number of this part = 1 (first RFID tag): code = 31
— Number of this part = 2 (second RFID tag): code = 32
— Number of this part = 3 (third RFID tag): code = 33
EXAMPLE 2 A set consisting of a single part with one RFID tag:
— Number of this part = 1: code = 11 (if present)
EXAMPLE 3 A set consists of 12 parts, and this is the fourth part:
— Number of this part = 4 (fourth RFID tag): code = 1204
EXAMPLE 4 A set having four parts but one part does not carry an RFID tag:
— Number of this part = 1 (first RFID tag): code = 40
— Number of this part = 2 (second RFID tag): code = 42
— Number of this part = 3 (third RFID tag): code = 43
— Number of this part = 4 (no RFID tag)
NOTE 1 The “0” of the first part serves two functions:
a) it indicates that not all parts have an RFID tag;
b) it indicates that this is the first part.
EXAMPLE 5 A set having an unknown number of parts or increasing in number of parts over time.
— Number of this part = 1 (first RFID tag): code = 01
— Number of this part = 2 (second RFID tag): code = 02
— Number of this part = 3 (third RFID tag): code = 03
— Number of this part = 4 (fourth RFID tag): code = 04
NOTE 2 The initial “0” indicates that the number of parts is not fixed.
4.2.5 Type of usage
4.2.5.1 General
The type of usage data element provides additional qualifying information about the item or part of a
set, for example, the type of material and its use within the library. As synergies between RFID-enabled
devices become more common, this data element can be set dynamically by one RFID device for the
benefit of another. Individual parts of a set can have different values for the type of usage data element.
If this data element is encoded, it shall use the values specified in Annex C.
4.2.5.2 Examples
EXAMPLE 1 An acquisition item that arrives at a library can be processed automatically if it has the following
type of usage parameters:
— Main qualifier = 0 (Class = acquisition item)
— Sub-qualifier = 1 (Sub-class = for automated processes)
EXAMPLE 2 If a similar acquisition item is only parameterized by a main qualifier, it can have the following
type of usage parameters:
— Main qualifier = 0 (Class = acquisition item)
— Sub-qualifier is absent means that the sub-class is unspecified (identical to sub-qualifier value zero)
EXAMPLE 3 An item for circulation that has to be handled with care and is not suited for automatic sorting
has the following type of usage parameters:
— Main qualifier = 1 (Class = item for circulation)
— Sub-qualifier = 2 (Sub-class = not for automatic sorting)
EXAMPLE 4 A discarded item that is offered for sale has the following type of usage parameters:
— Main qualifier = 7 (Class = discarded item)
— Sub-qualifier = 1 (Sub-class = for sale)
4.2.6 Shelf location
The shelf location data element holds the location of the item.
The data element can take any value the library decides to use. The values reflect the library's shelf
location system and are only intended for use in the library owning the item.
Automatic sorting systems can use this data element for sorting purposes.
4.2.7 ONIX media format
The ONIX media format data element shall, if encoded, represent an ONIX media descriptor of two
alphabetic characters.
These media descriptors are based on the ONIX Books Product Form Code List, published and
maintained by EDItEUR. Use the latest product form code from the ONIX Books Code Lists (see https://
www .editeur .org).
NOTE EDItEUR is the international group coordinating development of the standards infrastructure for
electronic commerce in the book and serials industries.
4.2.8 MARC media format
The MARC media format data element shall, if encoded, represent a MARC 21 category of material
descriptor.
This media descriptor is a compound of two letters defined by positions 6 and 7 in the leader of a
MARC 21 record. See https:// www .loc .gov/ marc/ bibliographic.
4.2.9 Supplier identifier
The supplier identifier data element is used for identification of the supplier of the item.
If a supplier code is determined by the purchasing library or its owner body (e.g. university, city,
government) there might be structure rules already in place. If not, it is recommended to define a
unique list on a national level. Annex D indicates a method using a country prefix.
4.2.10 Order number
The order number data element is used for an order number meaningful to the library and to the
supplier of the item.
4.2.11 ILL borrowing institution (ISIL)
The ILL borrowing institution (ISIL) data element is used for identification of an institution borrowing
the item.
When using this data element, the borrowing institution shall be represented by the ISIL code
according to ISO 15511. The data element is formatted according to similar rules as defined for the
owner institution (ISIL) data element (see 4.2.3). The ILL borrowing institution (ISIL) data element and
the alternative ILL borrowing institution data element (see 4.2.25) are mutually exclusive.
4.2.12 ILL borrowing transaction number
The ILL borrowing transaction number data element is used to identify an ILL transaction.
The ILL borrowing transaction number is assigned by the ILL transaction processing system and
encoded by the lending institution to identify an interlibrary loan transaction. The structure of the
number is locally defined.
4.2.13 GS1 product identifier
The GS1 product identifier data element shall, if encoded, be used to store the GTIN-13 code of GS1.
NOTE 1 GS1 is a global organization for standards and solutions to supply and demand chains globally and
across sectors.
The Global Trade Item Number (GTIN) is a code that identifies the product and not the individual item.
The GTIN-13 has 13 digits and is commonly seen on retail products in a bar code format and is (without
the check digit) also an element of tags used in retail that follow the electronic product code scheme of
GS1/EPC Global. The GTIN-13 code is commonly called the UPC code in the United States, and in other
parts of the world, it is known as the EAN-13 code.
NOTE 2 The Universal Product Code (UPC) is a specific type of bar code used for tracking trade items.
NOTE 3 The EAN-13 code is the European Article Number (EAN) 13 digit code.
The GTIN-13 code includes the encoding of:
— the ISBN, with the prefixes “978” and “979”;
— the ISSN with the prefix “977”;
— the ISMN with the prefix “979”.
The code structure for CDs, DVDs, and other products without formal registration codes follows
conventional GS1 rules. This means that for many products that originate in the United States, the code
shall be expanded with leading zeros to conform to the 13-digit structure. Codes on products from most
other countries use the full 13-digit structure. Encoding everything in a 13-digit structure is important
because the final digit is a check digit that can be used for validation processes in some systems.
4.2.14 Alternative unique item identifier
This data element is reserved for possibly encoding in new tag architectures.
4.2.15 Local data A
The local data A data element is used for any locally defined purpose. The structure and formatting is
locally defined.
4.2.16 Local data B
The local data B data element is used for any locally defined purpose. The structure and formatting is
locally defined.
4.2.17 Title
The title data element holds the title or titles of the library item.
4.2.18 Product identifier local
The product identifier local data element is used for a product code not based on the GTIN-13 codes.
This data element can be used for items that do not have a GTIN-13 code, or for which the GTIN-13 code
is not known or not adequate. This enables information systems linked to various code structures to be
supported by the RFID system.
4.2.19 Media format (other)
The media format (other) data element represents any media descriptor other than ONIX or MARC. See
Table 2.

4.2.20 Supply chain stage
The supply chain stage data element is used to identify the stage of the supply chain in which the item
currently resides. While current practice is for individual library institutions to add RFID tags to
their own material, this data element might become significant if tagging becomes more common at
“upstream” stages of the library material supply chain.
Table 3 lists the supply chain stage code decimal values that shall be used if this data element is encoded.

Other values for supply chain stage are reserved for future use and can only be encoded once they have
been defined in future editions of this document. For this specific data element, the value “0” indicates
“undefined”.
4.2.21 Supplier invoice number
The supplier invoice number data element is used for a locally designated invoice number meaningful
to the library and to the supplier of the library material.
This data element can be left permanently written to the tag or it can be used only temporarily during
an acquisitions process.
4.2.22 Alternative item identifier
The alternative item identifier data element is used for a locally designated optional identifier.
This data element can be temporary and have only local meaning as during an acquisitions process or it
can contain other identifiers as deemed necessary.
4.2.23 Alternative owner institution
The alternative owner institution data element is used for an alternative identification of the library
institution (i.e. not ISIL).
The data element can be used, for example, where a library identifier scheme pre-dates the ISIL and
cannot easily be converted into an ISIL-compliant scheme. This data element can be used in exceptional
cases for the ISIL code, or parts of the ISIL code (see 4.2.3).
4.2.24 Subsidiary of an owner institution
The subsidiary of an owner institution data element is used to refine the identity to a level lower than
the ISIL, e.g. a branch or collection. As such it is an internal code defined within a library institution.
4.2.25 Alternative ILL borrowing institution
The alternative ILL borrowing institution data element is used for an alternative code for the ILL
borrowing institution (i.e. not ISIL).
This data element and the ILL borrowing institution (ISIL) data element (4.2.11) are mutually exclusive
and only one of them shall be encoded on the tag.
4.2.26 Local data C
The local data C data element is used for any locally defined purpose. The structure and formatting is
locally defined.

should be published on the website given in Annex A.
5 System data elements
5.1 System data versus user data
Many tags have organized their memory in such a way that the user and the system data are stored
in different memory compartments. Other parts of the ISO 28560 series provide the details of all
the system data that play a crucial role in the system architecture. Subclause 5.2 describes the most
important system data.
5.2 System data elements for identification and item security in libraries
5.2.1 General
ISO/IEC 15961-3 defines the rules for the application family identifier (AFI), the data format and the
object identifiers for RFID for item management.
The AFI, the data format and the object identifiers for RFID for item management shall be in accordance
with ISO/IEC 15961-3.
