BS ISO IEC 15961-2:2019 download.Information technology Data protocol for radio frequency identification (RFID) for item management.
The technology of radio frequency Identification (RFID) is based on non-contact electronic communication across an air interface, The structure of the bits stored on the memory of the RFID tag is invisible and accessible between the RFID tag and the interrogator only by the use of the appropriate air interface protocol, as specified in the appropriate part of ISO/IEC 18000. The transfer of data between the application and the interrogator in open systems requires data to be presented in a consistent manner on any RFID tag that is part of that open system. Application commands from the application and responses froni the interrogator also require being processed in a standard way. This is not only to allow equipment to be interoperable, but in the special case of the data carrier, for the data to be encoded on the RFID tag in one system implementation for It to be read at a later time in a completely different and unknown system implementation. The data bits stored on each RF1D tag need to be formatted in such a way as to be reliably read at the point of use if the RFID tag is to fulfil its basic objective.
Manufacturers of radio frequency identification equipment (interrogators, RFID tags, etc.) and the users of RFID technology require a standard-based data protocol for RFID for item management. ISO/IEC 15961 and ISO/IEC 15962 specify this data protocol, which is independent of any of the air interface standards defined in 1SQ/JCJ8tXQ. As such, the data protocol is a consistent component In the RFID system that may independently evolve to Include additional air interface protocols. The International Standards that comprise the data protocol are:
ISO/IEC 15961-1. which defines the transfer of data to and from the application, supported by appropriate application commands and responses;
— this document (ISO/IEC 15961-2), which defines the registration procedure of RFII) data constructs to ensure that the data protocol supports new applications, in a relatively straightforward manner, as they adopt RFI D technology. This can be achieved by the Registration Authority publishing regular updates of RFID Data Constructs Register that have been assigned, and as a means of incorporating these updates into the processes of ISO/IEC 15961-1:
— I&QjthC1S9613.. which defines the RFID data constructs and the rules that govern their use;
— ISO/IEC 15961-4. which defines the transfer of data associated with sensors and batteries to and from the application, supported by appropriate application commands and responses;
— ISO/IEC 15962, which specifies the overall process and the methodologies developed to format the
BS ISO IEC 15961-2 specifies the procedural requirements to maintain specific RFID data constructs. The data constructs are associated with managing open and closed applications that utilise RFID systems which conform to the data protocol defined in other parts of ISOJIEC 15961 and ISO/IEC 15962. and the air interface protocols of 1S/lEC_180Q0.
It also outlines the obligations of the Registration Authority and the application administrators, with respect to:
— the allocation of AFIs to particular applications defined by the application administrator;
— the allocation of data formats to particular applications defined by the application administrator;
— the registration of Root-OlDs, compliant with IS 1EC9B341. to any Unique Item Identifiers used in applications defined by the application administrator;
— the registration of Root-OlDs, compliant with ISO/1fC 9834-1. to any other data used in applications defined by the application administrator;
— the registration of various table-driven encoding schemes, compliant with ISO/IEC 15962.

3 Terms, definitions and abbreviated terms
Application Family Identifier
mechanism used in the data protocol and the air interface protocol to select a class of RFII) tags relevant to an application, or aspect of an application, and to ignore further communications with other classes of RFID tags with different identifiers
3.1.3
arc
specific branch of a hierarchical Object Identifier tree
Note I to entry: The top three arcs of Object Identifiers relevant to RFID, compliant with ISO/IEC 9834-1. are defined in ISO/IEC 15961-3.
3.1.4
data format
mechanism used in the data protocol to identify how Object Identifiers are encoded on the RFID tag, and (where possible) identify a particular data dictionary for the set of relevant Object Identifiers for a specific application
3.1.5
Object
well-defined piece of information, definition or specification which requires a name in order to identify its use in an instance of communication
3.1.6
Object identifier
value (distinguishable from all other such values) which is associated with an Object
3.1.7
Relative- 01 D
Object identifier comprising the remaining arc or arcs positioned after a common Root-OlD (for the
first and subsequent arcs)
Note Ito entry: The common Root-OlD is often implied by other data constructs and not encoded in the RFID tag.
3.1.8
Root-OID
4 User considerations of RFID data constructs
Data constructs shall be applied in accordance with Annex A to ensure that application standards are correctly structured. Furthermore, an understanding of the functions of the data construct rules is essential for application administrators to apply for the relevant registration as defined in Clause 5.
5 Application administrators
5.1 General considerations
The procedure for the requests for RFID data constructs shall be as follows.
a) Applications for RFID data constructs shall contain all of the elements necessary to fulfil the requirements specified in ISO/IEC 15961-3 for Application Family Identifiers, data formats, Unique Item Identifiers and other data objects (if relevant to the application).
b) Application forms shall be made available on request from the Registration Authority.
c) A separate application form should be submitted to the Registration Authority for every RFID data construct set requested.
d) Only applications that have been duly completed shall be acceptable for registration by the Registration Authority.
e) All applications shall be reviewed by the Registration Authority for the registration and the assignment of a set of RFID data constructs. The Registration Authority may request additional information where further clarification is needed.
f) All completed application forms containing the assigned RFID data constructs (AFI, data format. and any Object Identifier) assigned should be retained by the involved parties.
g) The Registration Authority should obtain evidence of the use of the assigned RFID data constructs in the open application environment relevant to the applicant within a reasonable timeframe, preferably within 12 months of the date of the assignment.
