Information and documentation — RFID in libraries — Part 3: Fixed length encoding

This document 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 national, academic, public, corporate, special, and school libraries). This document 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.

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

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
