Information and documentation — RFID in libraries — Part 2: Encoding of RFID data elements based on rules from ISO/IEC 15962

This document 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 document 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 document provides essential standards-based information about RFID in libraries. A source of additional information about implementation issues is provided in Annex A.

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 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 document 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 document, 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 conformance with this document, the reading system can achieve a
degree of interoperability.
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.

relevant to an application, or aspect of an application, and to ignore further communications with other
classes of RFID tags with different identifiers
3.5
arc
specific branch of an object identifier tree, with new arcs added as required to define a particular object
Note 1 to entry: The top three arcs of all object identifiers are compliant with ISO/IEC 9834-1, ensuring
uniqueness.
3.6
data format
mechanism used in the data protocol to identify how object identifiers (3.11) are encoded on the RFID
tag, and (where possible) identify a particular data dictionary for the set of relevant object identifiers
for that application
Note 1 to entry: The data format declares the Root-OID (3.13) in an efficient manner, so that a complete object
identifier (3.11) can be reconstructed for external communications.

3.10
metadata
type of data or information about data
Note 1 to entry: In the context of this document, metadata (3.10) can be the Relative-OID (3.12) in relation to the
data, the precursor in relation to the compacted and encoded bytes, or the AFI (3.4) and DSFID (3.8) in relation to
the data.

value (distinguishable from all other such values), which is associated with an object
3.12
Relative-OID
particular object identifier (3.11) that constitutes the remaining arcs (3.5) after the Root-OID (3.13)
3.13
Root-OID
particular object identifier (3.11) that constitutes the first, second, and subsequent common arcs (3.5) of
a set of object identifiers (hence the common root)
3.14
tag driver
implementation of the process to transfer data between the data protocol processor and the RFID tag
4 Applicability and relationship with other systems
Figure 1 gives an overview of the relationship of this document with other systems. This document
defines a set of technical features while addressing a number of operational issues. This document
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.
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
document, 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 document, libraries will have increased flexibility with a number of features as
follows.
— Beyond the minimum of mandatory data elements defined in this document, libraries are 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.
— 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 document, is provided with
future options to cope with changes within the RFID equipment as the technology deve

FINAL DRAFT INTERNATIONAL STANDARD ISO/FDIS 28560-2:2023(E)
Information and documentation — RFID in libraries —
Part 2:
Encoding of RFID data elements based on rules from ISO/
IEC 15962
1 Scope
This document 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 document defines the technical characteristics required to encode the data elements defined in
ISO 28560-1 according to 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 document provides essential standards-based information about RFID in libraries. A source of
additional information about implementation issues is provided in Annex A.

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 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 document 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 document, 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 conformance with this document, the reading system mightcan achieve a degree
of interoperability.
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.

4.1 Figure 1 gives an overview of the relationship of this document with other systems. This document
defines a set of technical features while addressing a number of operational issues. This document
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
document, 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 document, libraries will have increased flexibility with a number of features as
follows.
— Beyond the minimum of mandatory data elements defined in this document, libraries are 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.
— 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 document, 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.
