20、14(E)IntroductionLibraries are implementing radio frequency identification (RFID) 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-e

21、ffectiveness 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 publ

22、ic 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

23、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

24、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 librar

25、y.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

26、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 com

27、pliance with ISO 28560-2, the reading system might achieve a degree of interoperability.This International Standard 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

28、migrate between different types of legacy system and encoding rules of this International Standard.

40、of data elements.4.2 RFID air interface4.2.1 Air interface conformanceThe air interface for compliant tags shall be in accordance with the specification for Mode 1.For migration purposes, additional non-compliant air interfaces used in legacy systems can be supported during a transition period, whic

41、h is permitted to remain in place for years, as necessary.The air interface conformance shall be tested in accordance with ISO/IEC TR 18047-3.4.2.2 Tag performanceWhere there are requirements for test tag performance, these shall be performed in accordance with ISO/IEC 18046-3.4.3 Data protocolThe f

42、ixed length encoding described in this part of ISO 28560 does not require a separate data protocol.5 General encoding rules5.1 Distinguishing from other applications and encodingsThe value of the application family identifier (AFI) is used to distinguish tags for library applications from other appl

43、ications. The values of AFI for library applications are defined in ISO 28560-1.ISO 28560-1 describes how the data storage format identifier (DSFID), if present in the system memory as a programmable register, is used to distinguish tags in the library application area, i.e. with the same AFI.Tags e

44、ncoded according to this part of ISO 28560 shall be programmed with the value 3EHEXin the DSFID register if the tag contains a programmable DSFID register.This part of ISO 28560 is not able to encode the DSFID if the tag does not contain a programmable DSFID register. In this case, ISO 28560-2 encod

45、es the DSFID in the first byte of the working area of the tag. To take this situation into account, the content parameter (see Table 1) shall not take the value 6 on RFID tags encoded according to this part of ISO 28560.If and only if the tag does not contain a programmable DSFID register, it is per

46、missible to distinguish tags encoded according to this part of ISO 28560 from other encodings by verifying the cyclic redundancy check (CRC) encoded in the basic block (see 7.2).5.2 Writing/reading directionData shall be written to and read from the tag as specified in ISO/IEC 18000-3, Mode 1, such

47、that the first bit transmitted to or from the tag is the least significant bit of the first field of the basic block. This field contains the content parameter (see Table 1).

49、library.If the size of the RFID tag is limited to 256 bits (32 bytes), the RFID tag can only contain a truncated basic block.If the size of the RFID tag is greater than 256 bits, extension blocks (structured or unstructured) can be inserted after the basic block up to the capacity of the chip. If extension blocks are inserted, the order of these is optional. The length of an extension block is determined by the first byte of the block. The type of extension block is defined in the following two bytes.Filler data blocks m
