ISO 28560-2:2018 情報とドキュメント—ライブラリ内のRFID —パート2：ISO / IEC15962のルールに基づくRFIDデータ要素のエンコード | ページ 6

3.1

access method

component of the DSFID (3.8) that is responsible for declaring the ISO/IEC 15962 compaction and encoding rules on an RFID tag

3.2

air interface protocol

rules of communication between an RFID interrogator and the RFID tag of a particular type, covering: frequency, modulation, bit encoding, and command sets

3.3

application command

instruction issued from the application to the ISO/IEC 15962 data protocol processor in order to initiate an action or operation with the RFID tag(s) via the interrogator

3.4

AFI

application family identifier

mechanism used in the data protocol and the air interface protocol (3.2) to select a class of RFID tags relevant to an application, or aspect of an application, and to ignore further communications with other classes of RFID tags with different identifiers

3.5

arc

specific branch of an object identifier tree, with new arcs added as required to define a particular object

Note 1 to entry: The top three arcs of all object identifiers are compliant with ISO/IEC 9834-1, ensuring uniqueness.

3.6

data format

mechanism used in the data protocol to identify how object identifiers (3.11) are encoded on the RFID tag, and (where possible) identify a particular data dictionary for the set of relevant object identifiers for that application

Note 1 to entry: The data format declares the Root-OID (3.13) in an efficient manner, so that a complete object identifier (3.11) can be reconstructed for external communications.

3.7

data protocol process

implementation of the processes defined in ISO/IEC 15962, including data compaction, formatting, support of the command/response unit, and an interface to the tag driver

3.8

DSFID

data storage format identifier

code that consists of, at least, the access method (3.1) and data format (3.6)

3.9

digital vandalism

unauthorized modification of data on an RFID tag that either renders it unusable or falsely represents another identifier

3.10

metadata

type of data or information about data

Note 1 to entry: In the context of this document, metadata (3.10) can be the Relative-OID (3.12) in relation to the data, the precursor in relation to the compacted and encoded bytes, or the AFI (3.4) and DSFID (3.8) in relation to the data.

3.11

object identifier

value (distinguishable from all other such values), which is associated with an object

3.12

Relative-OID

particular object identifier (3.11) that constitutes the remaining arcs (3.5) after the Root-OID (3.13)

3.13

Root-OID

particular object identifier (3.11) that constitutes the first, second, and subsequent common arcs (3.5) of a set of object identifiers (hence the common root)

3.14

tag driver

implementation of the process to transfer data between the data protocol processor and the RFID tag
