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. 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. ISO defines the set of mandatory and optional data elements. Depending on the technologies being used, and other features of tags that are claiming compliance with this part of ISOthe reading system might achieve a degree of interoperability. 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 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. A source of additional information about implementation issues is provided in Annex A. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document including any amendments applies. Data protocol — Part 1: This part of ISO defines a set of technical features while addressing a number of operational issues.
This part of ISO interfaces with four other activities, but with a clearly defined overlap.
As the use of RFID in libraries moves towards a more standardized approach as defined in this part of ISOthe characteristics and architecture systems izo change compared to those already established. This includes ensuring that new open systems applications do not corrupt the established base of RFID systems in libraries.
NOTE There is a degree of flexibility in using locally defined codes that enable enhancements and variations to be implemented whilst still complying with the basic set of data elements. For migration purposes, additional non-compliant air interfaces used jso legacy systems may be supported during a transition period, which is permitted to remain in place for years as necessary.
The relevant commands are described in Annex B. In particular, the following constraints shall apply. No alternative access method shall be supported until this part of ISO is revised.
ISO/IEC 15962 – RFID Data Protocol
Particular standards are specified in this part of ISO Only one data element is mandatory, the primary item identifier. A maximum length of characters should apply to all data elements that have a variable length display format. A special encoding scheme, as defined in 6. This is the only mandatory data element that is required to be encoded to be compliant with this part of ISO Although locking the primary item identifier is optional, under normal circumstances this data element should be locked to prevent various forms of digital vandalism.
The primary item identifier shall be encoded as the first data element on the RFID tag to allow for faster transactions across the air interface by invoking a read first object s argument in the read command see B. It should be used if additional data elements are encoded on the RFID tag. If used, it can be an aid to faster reading, because it indicates the presence or absence of a particular data element.
If the desired data element is encoded on the tag, then additional reading is required, whereas if the OID index indicates that it is not on the tag, the wasted transaction time can be eliminated. The index itself consists of a bit sequence, where each bit position is associated with a particular Relative-OID.
An example is shown in Figure 2. Irrespective of whether the data dictionary includes other Relative-OID values, the bit map can be truncated at this last Relative-OID that is encoded.
It is also necessary to round up the bit map to 8-bit boundaries for encoding on the RFID tag. If this data element is encoded on the RFID tag, it should be in the second position so that the data capture system can be set up to read the primary item identifier and the OID index in a single read process. This data element provides no information about the sequence of the encoded data elements, nor their size.
In the example in Figure 2, the encoding sequence could be Relative-OID value 8 followed by 11 followed by 3. This means that the hyphen present in every ISIL code following the two-character country code is presented in the application commands. This annex also applies to the ILL borrowing institution 6.
The use of these codes assumes for example an external inter-library loans ILL system capable of tracking the item based on the unique combination of its primary item identifier and owner institution. While it may be deemed necessary to lock this data element, this is left optional as some libraries may choose to leave the data element unlocked so that it could be changed if necessary as a result of library mergers or transfer of collections, etc. Other applications may also make use of the ISIL.
If the total number of parts is 9 or less, then the user data can be presented as a 2-digit code to reduce the encoding requirement. If the total number of parts is between 10 and 99, then the user data is presented as a 4-digit code, with the lowest ordinal values shown as 00 to If the total number of parts is between andthen the user data is presented as a 6-digit code.
If the ordinal value is less thanit is prefixed by leading zeros to create a 3-digit number. The code in ISO is presented as an alphanumeric code, but is actually a single byte hexadecimal code and is encoded in this manner. A reference source for the code list is provided in ISO It may be left permanently written to the tag or it may be used only temporarily during an acquisitions process.

The data is presented according to 159662 rules defined in 6. This data element shall not be locked. The structure of the number is locally defined. The data element shall not be locked. A more detailed definition is provided in ISO The GTIN code is always 15692 as a digit code i. Table 2 identifies the parameters for the local data elements. The format may be UTF-8 to allow for titles to be encoded in a language other than those based on the extended Latin alphabet.
The following advice is intended to assist with encoding efficiency. It is also recommended that all uppercase characters be used as this encodes more efficiently. The length should be the shortest that is practical to satisfactorily identify the item from a small set of items e.
The parameters for the item title data element are defined in Table 3. This enables information systems linked to specific local code structures to be supported by the RFID system.
It is only used if either of the two 15692 standard codes is not supported locally. The code list is provided in ISO The Jso may be temporary and have only local meaning as during an acquisitions process or it may contain other identifiers as deemed necessary. While it may be deemed necessary to lock this data element, this is left optional.
Some libraries may choose to leave the data element unlocked so that it could be changed if necessary as a result of library mergers or transfer of collections, or a future migration to the ISIL code.
As such it is an internal code defined locally. This allows libraries complete flexibility in selecting from the present set of optional data elements as defined in this part of ISOand for supporting new data elements, should these be added at a future date. This flexibility can be implemented for different loan items, and changed over a period of time, depending on the requirements of the library system. This is because the data protocol has been designed to be independent of RFID air interface protocols and tag architectures.
The four RFID data constructs are described in 7. A library may use the AFI in one of two ways. This distinguishes library loan items from all other items using RFID in item management systems.
