This part of ISO/IEC 11694
20、is specific to optical memory cards using the linear recording method. Characteristics which apply to other specific recording methods shall be found in separate International Standards. This part of ISO/IEC 11694 defines a logical structure to facilitate the interchange of data written to optical m
21、emory cards using the linear recording method. All numbers in this part of ISO/IEC 11694 are written in decimal notation unless otherwise specified. All multi-byte numbers in this part of ISO/IEC 11694 are placed in their respective data structures and written to the media in “little-endian” format.
22、 This format puts the least significant byte of the number first, followed by the more significant byte(s). All examples that show hexadecimal values corresponding to displayed characters use the ASCII character set. Characters written to cards according to this specification can use any desired cha
23、racter set, as long as the character set is specified in the corresponding tag document.

26、ards Linear recording method Part 4: Logical data structures 3 Terms and definitions For the purposes of this document, the terms and definitions given in ISO/IEC 11694-4 and the following apply. 3.1 application computer application program which writes to or makes use of the data read from an optic
27、al memory card Note 1 to entry: This also applies more generally to a system that makes use of the card or the way the card is used. 3.2 data element set of data bytes that is only useful in its entirety EXAMPLE A persons surname or a JPEG file containing a single image. 3.3 data file a stream of by
28、tes which is referenced by a single entry in the cards directory Note 1 to entry: A data file can contain either a single data item (associated with a single tag) or a TLV stream having multiple data items. 3.4 data item data element or well-defined set of data elements that is associated with a sin
29、gle tag, which defines its meaning and layout INTERNATIONAL ST ANDARD ISO/IEC 11694-5:2014(E) ISO/IEC 2014 All rights reserved 1BS ISO/IEC 11694-5:2014ISO/IEC 11694-5:2014(E) 3.5 data sector sector (as defined in ISO/IEC 11694-4) that contains all or part of a data file 3.6 directory structure used
30、to keep track of the presence and location of data on a random access storage media 3.7 directory sector sector on a random access media that contains directory information 3.8 layout specific sequence of bytes required in the data item Note 1 to entry: This is in contrast to the meaning of the data
31、 item, which describes its use. EXAMPLE A card can contain two JPEG “files”. The layout of these items is the same, but the meaning can be different. One can be a portrait of the card holder, and the other can be an image of the card holders fingerprint, for example. 3.9 little-endian format format
32、for defining the order of bytes in a multi-byte number Note 1 to entry: This format is sometimes referred to as “Intel” format. The first byte of a multi-byte number contains the least significant byte of the number, and the last byte contains the most significant byte of the number. EXAMPLE If the
33、decimal number 8765 (which is expressed as 223D in hexadecimal notation) is written out as a 16-bit quantity in little-endian format, the series of bytes containing the number is: 3D followed by 22. So the least significant byte (3D hex) is written out followed by the most significant byte (22 hex).
34、 3.10 logical track sequence of bytes, the length of which is the data capacity of a track, which make up part of a file EXAMPLE A file can have a length that exceeds the capacity of a single track on the card. In such a case, the file shall be broken up into several pieces, each of which shall be w
35、ritten to a different track on the card. The reading application shall put the pieces of the file back together after it has read all the tracks containing the file. Each of these “pieces” is considered a “logical track”, with the first piece containing the beginning of the file being counted as log
36、ical track zero. Most of the time, the logical tracks will be written to succeeding physical tracks, so if a file is written starting at physical track 8 for 2 tracks, logical track 0 occupies track 8 and logical track 1 occupies track 9. In some cases, a given logical track can be written twice, so
37、 it can be that the reading application finds logical track 0 at both physical tracks 8 and 9 and finds logical track 1 at physical track 10. In this case, the reader shall ignore the second copy of logical track 0 and paste the contents of tracks 8 and 10 together to form the original file. 3.11 me
38、aning use to which the data item can be put EXAMPLE The data associated with a given tag can have the meaning that it is a colour photograph of the head of the person to whom the card was issued. 3.12 physical track track on the optical memory stripe that is referenced by a physical track address as
39、 defined in ISO/IEC 11694-42 ISO/IEC 2014 All rights reservedBS ISO/IEC 11694-5:2014ISO/IEC 11694-5:2014(E) 3.13 public zone part of the optical stripe on the card that is accessible to all optical card drives Note 1 to entry: Optical memory cards can also contain a private zone that is accessible t
40、o only a specific set of card drives operated by the card issuer. 3.14 tag unique unsigned 16-bit number in the range 0 through 65535 (inclusive) that is used to identify a data item stored on the card Note 1 to entry: A single set of tags applies to any and all data stored in the pubic zone of an o
41、ptical memory card that conforms to this part of ISO/IEC 11694. 3.15 tag document document that completely describes both the meaning and the layout of one or more data items associated with a tag or a numerically contiguous group of tags Note 1 to entry: This document is created by the body which w
42、ishes to issue or update cards and is submitted to the tag issuing body for publication. An organization that desires to create or read and use the described data item(s) shall be able to do so by reading the tag document and any references incorporated in the tag document. 3.16 tag issuing body org
43、anization responsible for issuing tags to organizations which wish to issue or update cards complying with this part of ISO/IEC 11694 Note 1 to entry: The tag issuing body maintains a list of tags to ensure that each tag corresponds to a unique type of data item and publishes tag documents which des
44、cribe the meaning and layout of the data associated with each tag. It is proposed that HID Global be the tag issuing body for ISO/IEC 11694-5. 3.17 tag, length, value (TLV) data stream data storage structure that involves placing multiple data items in serial fashion on a storage medium and keeping
45、track of these items through a tag Note 1 to entry: The tag identifies the meaning and layout of the data, followed by the length of the data in bytes, followed by the value, which is the data itself. The last byte of the “value” part is then optionally followed by another TLV structure within the s
46、tream. The stream is terminated by a “tag” of zero. Although such a data stream is a serial entity, a random access technology can contain any number of such streams, and parts of a TLV stream can be read independently if desired. Each TLV data stream is contained in a file that is referenced by a s
47、ingle entry in the cards directory. 3.18 track physical location on an optical memory card that can contain one or more sectors Note 1 to entry: This term is the same as the term “physical track” and is defined in ISO/IEC 11694-4. 3.19 unique stamp unique 12-byte value that is created based on the t
48、ime of writing and the unique serial number of the optical memory card writing device Note 1 to entry: This stamp is used to identify two separate sectors as containing parts of the same data file. 4 General structure The purpose of this part of ISO/IEC 11694 is to allow for the interchange of data
49、on optical cards by specifying both the directory structure on the card and the method of identifying individual data ISO/IEC 2014 All rights reserved 3BS ISO/IEC 11694-5:2014ISO/IEC 11694-5:2014(E) elements that are written to the card. The directory provides a mapping between the identity of a data element and that elements location on the card. Tags are used to identify data elements both in their meaning and in the layout of the referenced data. This document defines the starting location of t
