8、and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal

9、with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC

10、have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the jo

11、int technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. In exceptional circumstances, when the joint technical committee has collected data of a different kind from that w

12、hich is normally published as an International Standard (“state of the art”, for example), it may decide to publish a Technical Report. A Technical Report is entirely informative in nature and shall be subject to review every five years in the same manner as an International Standard. Attention is d

13、rawn to the possibility that some of the elements of this Technical Report may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. ISO/IEC TR 29162 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, S

ISO/IEC TR 29162:2012(E) ISO/IEC 2012 All rights reserved vIntroduction Radio frequency identification (RFID) is one of the AIDC media widely used in the market place. Linear bar codes and two-dimensional symbols have long util

15、ized AIDC media. The international standard for AIDC syntax is ISO/IEC 15434. ISO/IEC 15961 and ISO/IEC 15962 were developed as encoding rules for RFID. Users have long utilized linear bar codes and two-dimensional symbols for item identification and numerous RFID technologies have recently been dev

16、eloped. Users who want to utilize RFID transponders should consider compatibility with linear bar codes and two-dimensional symbols already in the system. Because of the growing diversity and complexity of AIDC media in the market place, especially in RFID, it is not easy for users to understand how

17、 to read and write their data to each application of AIDC media. This Technical Report explains common data structures used in both optically readable media (linear bar codes and two-dimensional symbols) and radio-frequency identification. It primarily addresses the use of ASC MH10 Data Identifiers

18、to provide the semantics, ISO/IEC 15434 to provide the syntax, and ISO techniques of unique item identification with ISO/IEC 15961 Application Family Identifiers (AFIs) and encoding rules for RFID using ISO/IEC 15962. Those interested in applications using Air Transport Association (ATA) SPEC 2000,

19、Text Element Identifiers, are encouraged to contact the ATA for specific guidance. Those interested in applications using GS1 Application Identifiers and EPC, specifically for material found in the EPC Tag Data Standard (TDS), are encouraged to contact GS1 for specific guidance.

26、edia AIDC media in various forms are transported and/or stored, together with goods or items. ISO/IEC 15434 was developed as a syntax for high capacity AIDC media and applied to many kinds of two- dimensional symbols. ISO/IEC 15961 and ISO/IEC 15962 were developed for RFID air interface standards, a

27、s an encoding method only for RFID. For the sake of simplicity, users want to use a single data standard for the various forms of AIDC media. (See Figure 1). However, because of the inherent characteristics of RFID and optical technologies, differences in data encoding arise, some of which will be d

28、escribed within this Technical Report. Figure 1 Application user requirement For example, bar codes are always scanned one at a time, but a large population of RFID tags can be inventoried nearly simultaneously. To support the RFID inventory operation, the Unique Item Identificaiton (UII) of the RFI

29、D tag is prefaced by “filtering” information (a numbering system identifier or an AFI) that has no correlation in bar code systems. ISO/IEC TR 29162:2012(E) ISO/IEC 2012 All rights reserved 3As a second example, for faster inventory operations, many RFID tag architectures transmit only the UII porti

30、on of their data during inventory, sending item attendant data only upon request. In contrast, a 2D symbol reader always obtains and transmits the full contents simultaneously (both UII and item attendant data). Since the 1970s, linear bar code symbols have typically encoded application-specific “li

31、cense plate” item information. The bar code symbol encodes an identifying primary key to a database entry that contains current information about the item. If the bar code identifier is not serialized (UPC symbols are an example), it identifies a class of item, such as a certain product of a certain

32、 size. If serialized, the “license plate” identifies a specific instance of an item; in open system applications, it is important that the identification system can guarantee that each “license plate” is uniquely distinct from all others. Unique Item Identifiers (UIIs) can be contained in “unique id

33、entification-only” media such as a license-plate bar code symbol or an RFID tag containing only a UII. In the case of “unique identification-only,” a database or look-up to trading partner communications is required to establish additional information about the entity to which the UII is attached. T

34、echnologies such as two-dimensional symbols and data rich RF tags can contain this additional “item attendant data” within that medium. A number of ISO/IEC specifications have been developed for encoding and decoding of linear bar code symbologies, such as ISO/IEC 15420 for EAN/UPC and ISO/IEC 15417

35、 for Code 128, and for two- dimensional symbologies, such as ISO/IEC 15438 for PDF417 (see Bibliography for a complete list). The remainder of this technical report describes currently available methods for encoding both UII and item attendant data in optical and RFID media. For all two-dimensional

36、symbols, the data syntax specified in ISO/IEC 15434 (and summarized in Section 6 of this Technical Report) can be used. For most RFID data carriers, the UII is encoded separately (for efficient inventory operations), and the item attendant data should be encoded using ISO/IEC 15434 syntax. The RFID

37、encoding options are summarized in Sections 7, 8, and 9 of this Technical Report, and additional RFID-specific guidance is provided in Sections 10, 11, and the Annexes A through D 6 ISO/IEC 15434 application for high capacity AIDC media ISO/IEC 15434 is a transfer structure, syntax and coding of mes

38、sages and data formats when using high capacity AIDC media between trading partners, specifically between suppliers and recipients and, where applicable, in support of carrier applications such as bills of lading and carrier sorting and tracking; ISO/IEC 15434 includes encoded data: used in the ship

39、ping, receiving and inventory of transport units; contained within supporting documentation, in paper or electronic form, related to unit loads or transport packages; used in the sorting and tracking of transport units; used for the sorting and tracking of returnable transport items; used for the so

40、rting and tracking of products and product packages. To allow multiple data formats to be contained within a data stream, a two level structure of enveloping is employed. The outermost layer of the message is a Message Envelope that defines the beginning and end of the message. Within the Message En

41、velope are one or more Format Envelopes that contain the data (See Figure 2). Multiple formats in a single message should be employed only through trading partner agreements.

46、1980s, it became apparent that the need existed to encode more than simple product identity. Lot/batch and serial numbers, purchase order numbers, destination postal codes, country of origin and a unique license plate for the entity might all need to be encoded on a single label. Schemes in various

47、industries evolved until the cross-industry exchange of product forced standardization of tags, or prefixes, to identify the information encoded in the bar code. This gave rise to the standardization of Data Identifiers (DIs) and Application Identifiers (AIs), referred to as the semantics of an AIDC

48、 data structure, managed by ASC MH10 (DIs) and GS1 (AIs) as defined in ISO/IEC 15418. Over time, applications were developed for encoding the information on a shipping label into a single symbol, permitting the information to be read with a single scan. The ability to encode multiple data fields int

49、o a symbol created the requirement to know whether DIs or AIs were being read, where the various structures ended and others began, and when one would know that no more data followed. This gave rise to the standardization of data structures into messages, referred to as the syntax of an AIDC message, and was codified in ANS MH10.8.3 and later in ISO/IEC 15434.
