National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organizatio

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, IS

    15、O and IEC 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

    16、 by the joint 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.

    18、Introduction The purpose of this International Standard is to define the datatype of an identifier for the purposes of identifying participants in learning, education and training. Participants may be users, teachers, agents, groups, organizations, institutions, etc. BSISO/IEC24703:2004INTENRATIONAL

    19、 TSANDADR IS/OIE30742 C:(4002E)1Information technology Participant identifiers 1 Scope This International Standard specifies the datatype of participant identifiers in learning, education and training. Security and protection of personal data associated with the use of a participant identifier is no

    20、t addressed in this standard. The naming policy, registration, and authentication of participant identifiers are outside the scope of this International Standard. NOTE There is a risk of improper access and misuse of personal and private data facilitated by the use of a participant identifier. It is

    21、 the responsibility of the implementer to ensure proper use of a participant identifier. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition

    22、of the referenced document (including any amendments) applies. ISO/IEC 2382-1, Information technology Vocabulary Part 1: Fundamental terms ISO/IEC 10646-1, Information technology Universal Multiple-Octet Coded Character Set (UCS) Part 1: Architecture and Basic Multilingual Plane ISO/IEC TR 10176, In

    23、formation technology Guidelines for the preparation of programming language standards ISO/IEC 11404, Information technology Programming languages, their environments and system software interfaces Language-independent datatypes 3 Terms and definitions For the purposes of this document, the terms and

    24、 definitions given in ISO/IEC 2382-1 and the following apply. 3.1 abstract character character of the ISO/IEC 10646-1 repertoire (UCS) that is independent of encoding 3.2 binding application or mapping from one framework or specification to another 3.3 datatype set of distinct values, characterized

    25、by properties of those values and by operations on those values 3.4 encoding bit and byte format and representation of information BSISO/IEC24703:2004ISO/IEC 24703:2004(E) 2 I SO/IE 4002 C All irhgts seredevr3.5 implementation-defined behaviour unspecified behaviour where each implementation documen

The policy of singularity or non-singularity of identifiers is outside the scope of this International Standard.

    29、ticipant identifier shall conform to the requirements specified in: Clause 5, Clause 6, Clause 7, at least one binding of Clause 8 and Clause 9. 5 Functionality A participant identifier shall represent a designator. NOTE More than one participant identifier may be associated with an individual parti

    30、cipant. A participant identifier shall be a printable text string that should facilitate transcription by humans. EXAMPLE A 10-character string of digits is easier to transcribe than a 256-character string of mixed-case Latin characters. 6 Conceptual model A participant identifier is a string of abs

    31、tract characters that is associated with a participant. Conceptually, the participant identifier is “opaque” in that the string contains no information itself, e.g., “35267901“ has no particular meaning. Some implementations and administrators may choose participant identifiers that convey informati

    32、on, e.g., “doe.john“, and some participant identifiers may contain even more information, e.g., “building2-doe.john“. BSISO/IEC24703:2004IS/OIE30742 C:(4002E) I SO/IE 4002 C All irhgts seredevr 3A participant identifier may be used in several contexts, such as being embedded into filenames, URLs, or

    33、 E-mail addresses. Within information technology systems that manage participant information, participant identifiers may be used to link repositories to provide common and/or consolidated identification methods. 7 Semantics 7.1 Components of a participant identifier A participant identifier shall c

    34、onsist of identifier segments separated by segment separators. An identifier segment shall consist of identifier characters from the abstract character set. A segment separator shall be implementation-defined, but the period character “.“ is recommended. 7.2 ISO/IEC 11404 datatype definition The fol

    35、lowing datatype, given in ISO/IEC 11404 notation, defines the participant identifier: characterstring(ISO/IEC-10646-1) The smallest permitted maximum length of a participant identifier shall be 50 abstract characters. NOTE The parameter “ISO/IEC-10646-1“ identifies that abstract character repertoire

    36、, not its encoding. 7.3 Allowable abstract characters The abstract characters of a participant identifier shall be limited to the following set. The characters are named by their 16-bit hexadecimal name within the Basic Multilingual Plane of UCS. This subset of abstract characters is based on ISO/IE

    37、C TR 10176. 7.3.1 Identifier characters The following are non-digit, non-special abstract characters: Latin: 0041-005A, 0061-007A, 00AA, 00BA, 00C0-00D6, 00D8-00F6, 00F8-01F5, 01FA-0217, 0250-02A8, 1E00-1E9B, 1EA0-1EF9, 207F Greek: 0386, 0388-038A, 038C, 038E-03A1, 03A3-03CE, 03D0-03D6, 03DA, 03DC,
